Advanced Logarithmic Aggregation Operators for Enhanced Decision-Making in Uncertain Environments

Decision-making plays a pivotal role across various domains, spanning from medicine to business management, impacting critical sectors like computer science, automotive industries, and robotics. It serves as a logical and comprehensive approach to selecting the most suitable option from a range of possibilities, enhancing the dependability and efficiency of emergency response efforts, and reducing casualties, ecological damage, and financial losses. Traditionally, decision-making was seen as a process where all data related to criteria and their weights were clear numerical values. However, in reality, decisions often occur in environments where goals and constraints are unclear or ambiguous. This ambiguity underscores the importance of decision-making frameworks that can handle uncertainty, vagueness, and imprecision common in real-world scenarios. These frameworks provide valuable resources for decision-makers facing intricate and unclear situations, offering a structured approach to evaluating alternatives and selecting the optimal course of action. By incorporating multiple criteria, decision-making processes become more robust and adaptable, enabling organizations and individuals to navigate complex challenges effectively. In essence, decision-making is not just about choosing between options; it's about strategically managing uncertainty and ambiguity to achieve desired outcomes across diverse fields and industries.

Zadeh's fuzzy set [1], a pivotal concept in fuzzy logic and mathematics, extends the conventional idea of a classical set. This theory provides a robust framework for addressing uncertainty and vagueness in a mathematical manner. Its notable contribution lies in its capacity to handle real-world problems across various domains by offering a more adaptable and nuanced approach to representing and reasoning with imprecise data and concepts. Unlike classical set theory, fuzzy set theory introduces the notion of partial membership, allowing elements to belong to a set to varying degrees. This flexibility proves invaluable when dealing with ambiguous or unclear information. Fuzzy sets have diverse applications in decision-making across fields such as computer science, finance, management science, investment decisions, business, natural science, healthcare, robotics, automotive industries, social science, human resources, medicine industries, engineering science, manufacturing and operations, information technology, public policy, environmental management, and more. The inclusion of membership degrees facilitates a more comprehensive understanding of the degrees of belongingness to a set, thereby enhancing its relevance across a multitude of disciplines. However, challenges may arise in cases involving both unsatisfactory and satisfactory information simultaneously.

Atanassov [2] significantly expanded the concept of fuzzy sets by introducing IFSs, which incorporate a non-membership function alongside the traditional membership function. This innovation, governed by the constraint that their sum should not exceed one, was designed to address uncertainties characterized by vagueness, doubt, and ambiguity. IFSs have proven versatile, finding applications across diverse domains such as expert systems, management, computer science, pattern recognition, decision-making, and risk assessment. Particularly valuable in scenarios demanding decisions amid uncertainty or ambiguity, IFSs offer a nuanced framework for navigating real-world situations marked by incomplete or hesitant information. The inclusion of the non-membership function in IFSs enriches the representation of complex, uncertain, and incomplete data, facilitating more effective information processing across various applications. This approach enables a comprehensive understanding and adept management of situations where traditional models might struggle to capture the intricate nature of uncertain and incomplete data.

Aggregation operators play a crucial role in decision-making problems, especially in the context of the IF environment. Researchers such as Xu and Yager [3], Yager [4], and Xu [5] have introduced various operators using IFNs. These operators are designed to consolidate and combine diverse pieces of information, facilitating effective decision-making in complex scenarios. The applications and advantages of these operators have been explained, showcasing their relevance in addressing real-world problems. Yager and Kacprzyk [6] have dedicated significant efforts to understanding the importance of operators tailored for IFNs, contributing to the development of fundamental roles. Zhao and Wei [7] and Wang and Liu [8], [9] have introduced innovative methodologies by incorporating Einstein's operational principles. Through their research, they have not only developed new aggregation operators, but also thoroughly examined their structural properties and applications. These inherent structural characteristics play a pivotal role in enhancing the efficiency of these operators within computational processes. The versatility of these operators is evident as they find applications across diverse fields, showcasing their adaptability and utility in addressing a wide range of challenges. Researchers such as Garg [10], [11], Xu et al. [12], Dahlman et al. [13], Yu and She [14], Kumar and Garg [15], and Garg [16] have significantly advanced the field by introducing pioneering concepts and innovative approaches in their respective studies. Their work has played a crucial role in broadening our comprehension of IF operators and their practical applications. Rahman et al. [17], Gou et al. [18], Nancy and Garg [19], Jamil et al. [20], Garg and Nancy [21], and Garg et al. [22] have significantly contributed by introducing versatile and broadly applicable approaches that encompass IFSs and IVIFSs. Their work involves the presentation of diverse and generalized methodologies, highlighting the valuable insights and advancements they have brought to the field. Induced aggregation operators are mathematical functions crucial for combining multiple inputs into a unified output based on specific rules. Their purpose is to capture the aggregation process, reflecting relationships and interactions among input elements. These operators play a pivotal role in decision-making, fuzzy logic, and data analysis, serving as essential tools for amalgamating and summarizing information from diverse sources. Their significance lies in their ability to facilitate the integration and synthesis of data, enabling more informed and nuanced outcomes in fields reliant on intricate information processing. Logarithmic aggregation operators, a subset of induced aggregation operators, are particularly important in decision-making processes. These operators use logarithmic functions to analyze and combine information from various sources or criteria. The use of logarithmic functions allows for a comprehensive consideration of a broad range of values while emphasizing the significance of key factors. This approach enhances the decision-making process by providing a balanced and nuanced perspective, taking into account the varying degrees of importance assigned to different elements. Rahman [23], Li and Wei [24], Rahman et al. [25], and Qiyas et al. [26], presented logarithmic techniques, namely LIFWAA, LIFOWAA, LIFEWAA, LIFEOWAA, LIFEHAA, LIFEWGA, LIFEOWGA, LIFEHGA, LIFWGA, LIFOWGA, CLIFEWGA, CLIFEOWGA, CLIFEHGA, CLIFEWAA, CLIFEOWAA, CLIFEHAA, LCWAA, LCOWAA, LCWGA, LCOWGA operators. These methods offer significant value in tackling certain decision-making problems. These techniques prove particularly effective in addressing specific challenges inherent to decision-making processes. Researchers consistently operate under the assumption that decision-makers possess pertinent knowledge concerning the information linked to the objects under evaluation. This foundational understanding underpins the efficacy of logarithmic aggregation approaches in navigating complex decision scenarios. Their utility becomes apparent in situations where precise knowledge plays a crucial role in arriving at informed decisions. Nevertheless, in practical scenarios, this assumption may not be universally applicable. Yu [27], [28], Ma and Zeng [29], as well as pioneered the concept of a confidence level and subsequently developed various methodologies grounded in this notion. They introduced innovative techniques that leverage confidence levels, contributing to the advancement of this approach in their respective works. These methods were carefully crafted to handle challenges that arise when decision-makers lack expertise in a particular domain. The objective is to present a systematic approach that acknowledges and manages uncertainties, promoting more informed and resilient decision-making. The strategies are particularly tailored for situations where decision-makers may not possess expert-level knowledge, providing a structured framework that enhances adaptability and effectiveness when dealing with intricate problems. Wei [30], [31], Su et al. [32], and Xu et al. [33] introduced various induced aggregation operators, such as the I-IFOWA, I-IFOWG, I-IFHA, I-IFHG, I-IFEOWA operators, respectively. These operators are designed to aggregate data in various ways, offering diverse approaches to combining information for analysis or decision-making purposes. Induced aggregation operators are specifically crafted to combine data in diverse ways, allowing for nuanced and comprehensive analysis. Each operator offers a distinct approach to data aggregation, catering to specific needs and objectives in various contexts.

This paper draws inspiration from three separate ideas introduced in previous studies: the logarithmic concept [23], [24], [25], [26], the confidence concept [29], and the induced concept [30], [31], [32], [33]. Despite their relevance and potential synergies, prior research has, surprisingly, not attempted to integrate these three concepts. Our research focuses on merging three key concepts: the logarithmic concept, the confidence concept, and the induced concept. By integrating logarithmic aggregation operators within an inducing variable under a confidence level framework, we seek to capitalize on the strengths of all approaches, potentially offering fresh insights and better outcomes across various applications. The concept of an inducing variable is typically associated with decision-making scenarios involving uncertainty or when an additional influential factor needs consideration in the aggregation process. Our study stands out for its unique contribution to advancing existing methodologies by refining and expanding upon established models. Through this, we anticipate achieving enhanced performance and broader applicability in practical settings.

Utilizing real-world scenarios extensively, it not only affirms the efficacy of these operators but also offers valuable practical applications. This methodology not only validates the proposed operators but also emphasizes their significance in decision-making contexts.

The forthcoming paper is structured meticulously, comprising several sections that delve deeply into the intricacies of logarithmic operations and aggregation operators.

In Section 2, we lay down fundamental definitions that will underpin our subsequent investigations. This section serves as the groundwork upon which the rest of our research builds.

Moving on to Section 3, our focus shifts to elucidating the laws governing logarithmic operations. Here, we aim to provide a clear and concise presentation of these laws for a better comprehension of their application.

This thorough examination helps in understanding the behavior and characteristics of these operators. In Section 5, we present a novel emergency decision-making model, offering a fresh perspective on this critical subject matter. Our intent here is to shed light on a unique aspect of decision-making, particularly in situations of utmost importance. Section 6 is dedicated to demonstrating the practical utility of our proposed methods. Through an illustrative example, we employ various techniques to showcase how our approaches can be applied effectively in real-world scenarios. Following this, in Section 7, we conduct a comparative and sensitive analysis. This allows us to evaluate the efficacy and efficiency of our methods in comparison to existing approaches, thereby providing a deeper understanding of their strengths and limitations. In Section 8, the proposed techniques were subjected to experimental validation, where their effectiveness was rigorously assessed. Following this, in Section 9, a conclusive summary was provided, encapsulating the key findings and contributions of the research. This section serves to consolidate the outcomes of the study, offering a comprehensive understanding of the advancements made in the field.

In our research, we devised induced logarithmic operators that incorporate a confidence level. An inducing variable is a factor that directly impacts or triggers a particular outcome or phenomenon, eliciting a specific response within a system or process. The confidence level denotes the extent of certainty or trust in the accuracy of a result or decision, serving as a metric of reliability. Typically expressed as a percentage, it signifies the likelihood that the actual value falls within a specified range or interval, thereby indicating the level of confidence associated with the outcome.

Definition 1 [24]: Let $\quad I=\left\{\left\langle q, \gamma_I(q), \chi_I(q)\right\rangle \mid q \in \Re\right\} \quad$ is an $\quad \mathrm{IFS}, \quad \Re \quad$ is a $\quad$ universal $\quad$ set, and then $\log _r I=\left\{\left\langle q, 1-\log _r \gamma_I(q), \log _r\left(1-\chi_I(q)\right)\right\rangle \mid q \in \Re\right\}$ with $r \neq 1$ and $0 < r \leq \gamma \leq 1$. Membership and non-membership are denoted by $1-\log _r \gamma_I(q): \Re \rightarrow[ 0,1], \forall q \in \Re \rightarrow 1-\log _r \gamma_I(q) \in[ 0,1]$ and $1-\log _r \chi_I(q): \Re \rightarrow[ 0,1], \forall q \in \Re \rightarrow 1-\log _r \chi_I(q) \in[ 0,1] \quad$ respectively, $\quad$ under $\quad$ conditions: $0 \mathrm{p} 1-\log _r \chi_I(q)+\log _r\left(1-\chi_I(q)\right) \leq 1$.

When comparing two or more methods in research or data analysis, using score functions and accuracy functions can be valuable metrics. A score function, often referred to as a performance metric or evaluation measure, is a quantitative measure used to assess the quality or effectiveness of a model, algorithm, or method in various tasks, such as machine learning, optimization, or data analysis. The choice of a specific score function depends on the nature of the problem and the goals of the analysis. Accuracy is a specific type of score function that measures the correctness of predictions made by a model. In classification tasks, accuracy is often used and represents the ratio of correct predictions to the total number of predictions. It is a straightforward measure of overall model performance.

Definition 2 [3]: Let $\mathrm{h}=(\gamma, \chi)$, then its score and accuracy can be computed mathematically as: $s(\mathrm{h})=\gamma-\chi$ and $h(\mathrm{h})=\gamma+\chi$ respectively.

Definition 3 [3]: Let $\mathrm{h}_1$ and $\mathrm{h}_2$ be IFNs, then

i) If $s\left(\mathrm{h}_1\right) < s\left(\mathrm{h}_2\right)$, this show that $\mathrm{h}_1 < \mathrm{h}_2$

ii) If $s\left(\mathrm{h}_2\right) < s\left(\mathrm{h}_1\right)$, this show that $\mathrm{h}_2 < \mathrm{h}_1$

iii) If $s\left(\mathrm{h}_1\right)=s\left(\mathrm{h}_2\right)$, this show that $\mathrm{h}_1=\mathrm{h}_2$,

then we have some more conditions:

a) If $h\left(\mathrm{h}_1\right) < h\left(\mathrm{h}_2\right)$, this show that $\mathrm{h}_1 < \mathrm{h}_2$

b) If $h\left(\mathrm{h}_2\right) < h\left(\mathrm{h}_1\right)$, this show that $\mathrm{h}_2 < \mathrm{h}_1$

c) If $h\left(\mathrm{h}_1\right)=h\left(\mathrm{h}_2\right)$, this show that $\mathrm{h}_1=\mathrm{h}_2$.

Operational laws, particularly in the realm of mathematical operations and algebraic structures, are principles that dictate how specific operations behave. This paper focuses on logarithmic operational laws, which are mathematical rules governing the manipulation and simplification of logarithmic expressions. Logarithms, in this context, are mathematical functions depicting the exponent to which a certain base must be raised to produce a specified number. The developed laws in this study aim to elucidate the systematic procedures for handling and streamlining expressions involving logarithms.

Definition 4 [24]: Let $\mathrm{h}_j=\left(\gamma_j, \chi_j\right)(1 \leq j \leq 2)$ and a real number $\wp > 0$, then

$\text { i) } \quad \mathrm{h}_1+\mathrm{h}_2=\left(\frac{\gamma_1+\gamma_2}{1+\gamma_1 \gamma_2}, \frac{\chi_1 \chi_2}{1+\left(1-\chi_1\right)\left(1-\chi_2\right)}\right)$

$\text { ii) } \quad \mathrm{h}_1 \times \mathrm{h}_2=\left(\frac{\gamma_1 \gamma_2}{1+\left(1-\gamma_1\right)\left(1-\gamma_2\right)}, \frac{\chi_1+\chi_2}{1+\chi_1 \chi_2}\right)$

$\text { iii) } \quad \wp(\mathrm{h})=\left(\frac{(1+\gamma)^{\wp}-(1-\gamma)^{\wp}}{(1+\gamma)^{\wp}+(1-\gamma)^{\wp}}, \frac{2 \chi^{\wp}}{(2-\chi)^{\wp}+\chi^{\wp}}\right)$

$\text { iv) } \quad(\mathrm{h})^{\wp}=\left(\frac{2 \gamma^{\wp}}{(2-\gamma)^{\wp}+\gamma^{\wp}}, \frac{(1+\chi)^{\wp}-(1-\chi)^{\wp}}{(1+\chi)^{\S}+(1-\chi)^{\wp}}\right)$

$\text { v) } \quad \mathrm{h}_1 \cup \mathrm{h}_2=\left(\max \left\{\gamma_1, \gamma_2\right\}, \min \left\{\chi_1, \chi_2\right\}\right)$

$\text { vi) } \quad \mathrm{h}_1 \cap \mathrm{h}_2=\left(\min \left\{\gamma_1, \gamma_2\right\}, \max \left\{\chi_1, \chi_2\right\}\right)$

$\text { vii) } \quad(\mathrm{h})^c=(\chi, \gamma)$

Theorem 1: Let $\mathrm{h}_j=\left(\gamma_j, \chi_j\right)(1 \leq j \leq 3)$ with $r_j \neq 1$ and $0 \mathrm{p} r_j \leq \min \left\{\gamma_j,\left(1-\chi_j\right)\right\} \leq 1$, then

i) $\quad \log _r \mathrm{h}_1+\log _r \mathrm{h}_2=\log _r \mathrm{h}_2+\log _r \mathrm{h}_1$

ii) $\quad \log _r \mathrm{h}_1 \times \log _r \mathrm{h}_2=\log _r \mathrm{h}_2 \times \log _r \mathrm{h}_1$

iii) $\quad\left(\log _r \mathrm{h}_1+\log _r \mathrm{h}_2\right)+\log _r \mathrm{h}_3=\log _r \mathrm{h}_1+\left(\log _r \mathrm{h}_2+\log _r \mathrm{h}_3\right)$

iv) $\quad\left(\log _r \mathrm{h}_1 \times \log _r \mathrm{h}_2\right) \times \log _r \mathrm{h}_3=\log _r \mathrm{h}_1 \times\left(\log _r \mathrm{h}_2 \times \log _r \mathrm{h}_3\right)$

Proof: This theorem comprises four components, but our focus will be on demonstrating the validity of parts (i, ii). The remaining portions of the theorem can be straightforwardly proven employing a similar approach.

i) Since, by using Definition 4, we have

$ \begin{aligned} & \log _r \mathrm{h}_1+\log _r \mathrm{h}_2 \\ & =\left(\left(1-\log_r \gamma_1, \log_r\left(1-\chi_1\right)\right)+\left(1-\log_r \gamma_2, \log _r\left(1-\chi_2\right)\right)\right) \\ & =\left(\frac{\left(1-\log _r \gamma_1\right)+\left(1-\log _r \gamma_2\right)}{1+\left(1-\log _r \gamma_1\right)\left(1-\log _r \gamma_2\right)}, \frac{\log _r\left(1-\chi_1\right) \log _r\left(1-\chi_2\right)}{1+\left(1-\log _r\left(1-\chi_1\right)\right)\left(1-\log _r\left(1-\chi_2\right)\right)}\right) \\ & =\left(\frac{1-\log _r \gamma_2+1-\log _r \gamma_1}{1+\left(1-\log _r \gamma_2\right)\left(1-\log _r \gamma_1\right)}, \frac{\log _r\left(1-\chi_2\right) \log _r\left(1-\chi_1\right)}{1+\left(1-\log _r\left(1-\chi_2\right)\right)\left(1-\log _r\left(1-\chi_1\right)\right)}\right) \\ & =\log _r \mathrm{h}_2+\log _r \mathrm{h}_1 \end{aligned} $

ii) Again, by using Definition 4, we have

$ \begin{aligned} & \log _r \mathrm{h}_1 \times \log _r \mathrm{h}_2 \\ & =\left(\left(1-\log _r \gamma_1, \log _r\left(1-\chi_1\right)\right) \otimes\left(1-\log _r \gamma_2, \log _r\left(1-\chi_2\right)\right)\right) \\ & =\left(\frac{\log _r\left(1-\gamma_1\right) \log _r\left(1-\gamma_2\right)}{1+\left(1-\log _r\left(1-\gamma_1\right)\right)\left(1-\log _r\left(1-\gamma_2\right)\right)}, \frac{\left(1-\log _r \chi_1\right)+\left(1-\log _r \chi_2\right)}{1+\left(1-\log _r \chi_1\right)\left(1-\log _r \chi_2\right)}\right) \\ & =\left(\frac{\log _r\left(1-\gamma_2\right) \log _r\left(1-\gamma_1\right)}{1+\left(1-\log _r\left(1-\gamma_2\right)\right)\left(1-\log _r\left(1-\gamma_1\right)\right)}, \frac{1-\log _r \chi_2+1-\log _r \chi_1}{1+\left(1-\log _r \chi_2\right)\left(1-\log _r \chi_1\right)}\right) \\ & =\log _r \mathrm{h}_2 \times \log _r \mathrm{h}_1 \end{aligned} $

Thus, the proof is completed.

Theorem 2: Let $\mathrm{h}_j=\left(\gamma_j, \chi_j\right)(1 \leq j \leq 3)$ with $r_j \neq 1$ and $0 < r_j \leq \min \left\{\gamma_j,\left(1-\chi_j\right)\right\} \leq 1$, then

i) $\quad \log _r\left(\mathrm{h}_1 \cup \mathrm{h}_2\right) \cap \log _r \mathrm{h}_2=\log _r \mathrm{h}_2$

ii) $\quad \log _r\left(\mathrm{h}_1 \cap \mathrm{h}_2\right) \cup \log _r \mathrm{h}_2=\log _r \mathrm{h}_2$

iii) $\quad \log _r\left(\mathrm{h}_1 \cup \mathrm{h}_2\right) \cap \log _r \mathrm{h}_3=\log _r\left(\mathrm{h}_1 \cap \mathrm{h}_3\right) \cup \log _r\left(\mathrm{h}_2 \cap \mathrm{h}_3\right)$

iv) $\quad \log _r\left(\mathrm{h}_1 \cap \mathrm{h}_2\right) \cup \log _r \mathrm{h}_3=\log _r\left(\mathrm{h}_1 \cup \mathrm{h}_3\right) \cap \log _r\left(\mathrm{h}_2 \cup \mathrm{h}_3\right)$

Proof: This theorem consists of ten parts, but our attention will be directed towards proving the accuracy of parts (i, ii). The other aspects of the theorem can be easily demonstrated using a similar method. Therefore, applying Definition 4, we can express the following:

i) Since, by using Definition 4, we have

$ \begin{aligned} & \log _r\left(\mathrm{h}_1 \cup \mathrm{h}_2\right) \cap \log _r \mathrm{h}_2 \\ & =\log _r\left(\max \left\{\gamma_1, \gamma_2\right\}, \min \left\{\left(1-\chi_1\right),\left(1-\chi_2\right)\right\}\right) \cap \log _r\left(\gamma_2,\left(1-\chi_2\right)\right) \\ & =\log _r\left(\min \left\{\max \left\{\gamma_1, \gamma_2\right\}, \gamma_2\right\}, \max \left\{\min \left\{\left(1-\chi_1\right),\left(1-\chi_2\right)\right\},\left(1-\chi_2\right)\right\}\right) \\ & =\log _r\left(\gamma_2,\left(1-\chi_2\right)\right) \\ & =\log _r \mathrm{h}_2 \end{aligned} $

ii) By using Definition 4, we have

$ \begin{aligned} & \log _r\left(\mathrm{h}_1 \cap \mathrm{h}_2\right) \cup \log _r \mathrm{h}_2 \\ & =\log _r\left(\min \left\{\gamma_1, \gamma_2\right\}, \max \left\{\left(1-\gamma_1\right),\left(1-\gamma_2\right)\right\}\right) \cup \log _r\left(\gamma_2,\left(1-\gamma_2\right)\right) \\ & =\log _r\left(\max \left\{\min \left\{\gamma_1, \gamma_2\right\}, \gamma_2\right\}, \min \left\{\max \left\{\left(1-\gamma_1\right),\left(1-\gamma_2\right)\right\},\left(1-\gamma_2\right)\right\}\right) \\ & =\log _r\left(\eta_2,\left(1-\gamma_2\right)\right) \\ & =\log _r \mathrm{h}_2 \end{aligned} $

iii) Again, by using Definition 4, we have

$ \begin{aligned} & \log _r\left(\mathrm{h}_1 \cup \mathrm{h}_2\right) \cap \log _r \mathrm{h}_3 \\ & =\log _r\left(\max \left\{\gamma_1, \gamma_2\right\}, \min \left\{\left(1-\chi_1\right),\left(1-\chi_2\right)\right\}\right) \cap \log _r\left(\gamma_3,\left(1-\chi_3\right)\right) \\ & =\log _r\left(\min \left\{\max \left\{\gamma_1, \gamma_2\right\}, \gamma_3\right\}, \max \left\{\min \left\{\left(1-\chi_1\right),\left(1-\chi_2\right)\right\},\left(1-\chi_3\right)\right\}\right) \\ & =\log _r\left(\mathrm{h}_1 \cap \mathrm{h}_3\right) \cup \log _r\left(\mathrm{h}_2 \cap \mathrm{h}_3\right) \end{aligned} $

Thus, the proof is completed.

Logarithmic aggregation operators offer several advantages in decision-making processes. Firstly, they accommodate a wide range of input values, allowing for the integration of diverse data sets with varying scales. Secondly, they effectively handle extreme values, preventing them from disproportionately influencing the final outcome. Additionally, logarithmic aggregation operators maintain the multiplicative property, ensuring consistency in their application across different contexts. Moreover, they facilitate intuitive interpretation, as the logarithmic scale aligns with human perceptions of relative differences. Lastly, these operators promote robustness by reducing the impact of uncertainties or inaccuracies in the data, leading to more reliable decision outcomes. We present two novel techniques: the I-CLIFEOWGA operator and the I-CLIFEHGA operator. Notably, the I-CLIFEHGA operator represents a more comprehensive iteration of the I-CLIFEOWGA operator, incorporating additional elements, methods, or rules beyond simple averaging. Our analysis will delve into each operator, providing detailed insights along with illustrative examples to elucidate their structural nuances. We will specifically explore fundamental characteristics like monotonicity, idempotency, and boundedness inherent in these operators. These traits are pivotal in the decision-making process, offering a foundational understanding of how these aggregation methods contribute to the overall decision-making framework.

Definition 5: Let $\left(\ell_j,\left\langle\mathrm{h}_j, \phi_j\right\rangle\right)(j \leq n)$ be a finite family of IFNs, with their corresponding weights $\xi=\left(\xi_1, \xi_2, \ldots, \xi_n\right)$ with certain limitations, such as their sum is less than one or equal to one; let $\mathrm{h}_j \in\left\langle\mathrm{h}_j, \phi_j\right\rangle$ be the ordered pair of IFEOWG where the $\mathrm{j}^{\text {th}}$ largest value is known as the order inducing variable, with $\mathrm{h}_j \in\left\langle\mathrm{h}_j, \phi_j\right\rangle$ and $\mathrm{h}_j(1 \leq j \leq n)$ as the IF arguments. Then the I-CLIFEOWGA operator can be expressed mathematically as:

$\text {I-CLIFEOWGA}_{\xi}\left(\left\langle \ell_1,\left(\mathrm{h}_1,{ }\phi_1\right)\right\rangle, \ldots,\left\langle \ell_n,\left(\mathrm{h}_n,{ }\phi_n\right)\right\rangle\right)$

\[ = \left\{ \begin{array}{c} \left( \frac{2 \prod_{j=1}^n \left(1-\log_r \gamma_{\tau(j)}\right)^{\phi_j \xi_j}} {\prod_{j=1}^n \left(1+\log_r \gamma_{\tau(j)}\right)^{\phi_j \xi_j} + \prod_{j=1}^n \left(1-\log_r \gamma_{\tau(j)}\right)^{\phi_j \xi_j}}, \frac{\prod_{j=1}^n \left(1+\log_r (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j} - \prod_{j=1}^n \left(1-\log_r (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j}} {\prod_{j=1}^n \left(1+\log_r (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j} + \prod_{j=1}^n \left(1-\log_r (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j}} \right) \\ \text{where } r \neq 1 \text{ and } 0 < \frac{1}{r} \leq \min \left\{\gamma_{\tau(j)}, (1-\chi_{\tau(j)})\right\} \leq 1, \\ \left( \frac{2 \prod_{j=1}^n \left(1-\log_{\frac{1}{r}} \gamma_{\tau(j)}\right)^{\phi_j \xi_j}} {\prod_{j=1}^n \left(1+\log_{\frac{1}{r}} \gamma_{\tau(j)}\right)^{\phi_j \xi_j} + \prod_{j=1}^n \left(1-\log_{\frac{1}{r}} \gamma_{\tau(j)}\right)^{\phi_j \xi_j}}, \frac{\prod_{j=1}^n \left(1+\log_{\frac{1}{r}} (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j} - \prod_{j=1}^n \left(1-\log_{\frac{1}{r}} (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j}} {\prod_{j=1}^n \left(1+\log_{\frac{1}{r}} (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j} + \prod_{j=1}^n \left(1-\log_{\frac{1}{r}} (1-\chi_{\tau(j)})\right)^{\phi_j \xi_j}} \right) \\ \text{where } r \neq 1 \text{ and } 0 < \frac{1}{r} \leq \min \left\{\gamma_{\tau(j)}, (1-\chi_{\tau(j)})\right\} \leq 1 \end{array} \right. \]

Theorem 3: Let $\left(\ell_j,\left\langle\mathrm{h}_j, \phi_j\right\rangle\right)(1 \leq j \leq n)$ be IFNs and confidence level $\phi_j(1 \leq j \leq n)$, then the following four properties hold:

1) Commutatively: Assuming a collection of two tuples, such as $\left(\ell_j^*,\left\langle\mathrm{h}_j^*, \phi_j^*\right\rangle\right)(1 \leq j \leq n)$, then

where, $\left( \ell_j^*,\left\langle\mathrm{h}_j^*, \phi_j^*\right\rangle\right)(1 \leq j \leq n)$ is the rearrangement and reordering of $\left( \ell_j,\left\langle\mathrm{h}_j, \phi_j\right\rangle\right)(1 \leq j \leq n)$

2) Idempotency: Let $\left( \ell_j,\left\langle\mathrm{h}_j, \phi_j\right\rangle\right)(1 \leq j \leq n)=\mathrm{h}$ with $\phi_1=\phi_2=\ldots=\phi_n=\phi$, then

3) Boundedness: Assuming $\left(\ell_j,\left\langle\mathrm{h}_j, \phi_j\right\rangle\right)(1 \leq j \leq n)$ with $\mathrm{h}_{\max }=\left(\max _j\left\{\phi_j \gamma_j\right\}, \min _j\left\{\phi_j \chi_j\right\}\right)$

and $\mathrm{h}_{\min }=\left(\min _j\left\{\phi_j \gamma_j\right\}, \max _j\left\{\phi_j \chi_j\right\}\right)$, then the following holds.

4) Monotonicity: If $\left\langle \ell_j^*,\left(\mathrm{h}_j^*, \phi_j^*\right)\right\rangle$ is another collection IFNs, with $\gamma_j \leq \gamma_j^*$ and $\chi_j \geq \chi_j^*$, then

Example 1: Assuming five values, such as: $\mathrm{h}_1=\langle 0.20,(0.40,0.50), 0.50\rangle, \mathrm{h}_2=\langle 0.40,(0.40,0.50), 0.40\rangle$, $\mathrm{h}_3=\langle 0.50,(0.40,0.40), 0.70\rangle, \mathrm{h}_4=\langle 0.60,(0.50,0.30), 0.60\rangle, \mathrm{h}_5=\langle 0.80,(0.60,0.20), 0.80\rangle$ whose weights are $\xi=(0.1,0.2,0.2,0.2,0.3)$ and $r=0.2$. Next, we need to arrange these values according to the inducing variable:

$\mathrm{h}_5=\langle 0.80,(0.60,0.20), 0.80\rangle$,

$\mathrm{h}_4=\langle 0.60,(0.50,0.30), 0.60\rangle$,

$\mathrm{h}_3=\langle 0.50,(0.40,0.40), 0.70\rangle$,

$\mathrm{h}_2=\langle 0.40,(0.40,0.50), 0.40\rangle$,

$\mathrm{h}_1=\langle 0.20,(0.40,0.50), 0.50\rangle$.

Then, we have the new arrangement as:

$\mathrm{h}_{\tau(1)}=\langle 0.80,(0.60,0.20), 0.80\rangle$,

$\mathrm{h}_{\tau(2)}=\langle 0.60,(0.50,0.30), 0.60\rangle$,

$\mathrm{h}_{\tau(3)}=\langle 0.50,(0.40,0.40), 0.70\rangle$,

$\mathrm{h}_{\tau(4)}=\langle 0.40,(0.40,0.50), 0.40\rangle$,

$\mathrm{h}_{\tau(5)}=\langle 0.20,(0.40,0.50), 0.50\rangle$.

$\begin{aligned} & \prod_{j=1}^5\left(1-\log _r\left(1-\chi_\tau(1)\right)\right)^{\phi_j \xi_j}=\left(1-\log _{0.2}(1-0.20)\right)^{0.80 \times 0.1}\left(1-\log _{0.2}(1-0.30)\right)^{0.60 \times 0.2} \\ & \left(1-\log _{0.2}(1-0.40)\right)^{0.70 \times 0.2}\left(1-\log _{0.2}(1-0.50)\right)^{0.40 \times 0.2}\left(1-\log _{0.2}(1-0.50)\right)^{0.50 \times 0.3} \\ & =0.798\end{aligned}$

$\begin{aligned} & \prod_{j=1}^5\left(1+\log _r\left(1-\chi_\tau(j)\right)\right)^{\phi_j \xi_j}=\left(1+\log _{0.2}(1-0.20)\right)^{0.80 \times 0.1}\left(1+\log _{0.2}(1-0.30)\right)^{0.60 \times 0.2} \\ & \left(1+\log _{0.2}(1-0.40)\right)^{0.70 \times 0.2}\left(1+\log _{0.2}(1-0.50)\right)^{0.40 \times 0.2}\left(1+\log _{0.2}(1-0.50)\right)^{0.50 \times 0.3} \\ & =1.168\end{aligned}$

Next, using the I-LIFEOWGA operator, we have

$\text{I-CLIFEOWGA}_{\xi}\left(\left\langle \ell_1,\left(\mathrm{h}_1, \phi_1\right)\right\rangle,\left\langle \ell_2,\left(\mathrm{h}_2, \phi_2\right)\right\rangle, \ldots,\left\langle \ell_5,\left(\mathrm{h}_5, \phi_5\right)\right\rangle\right)$

$\left(\frac{2 \prod_{j=1}^n\left(1-\log _r \gamma_\tau(j)\right)^{\phi_j \xi_j}}{\prod_{j=1}^n\left(1+\log _r \gamma_{\tau(j)}\right)^{\phi_j \xi_j}+\prod_{j=1}^n\left(1-\log _r \gamma_{\tau(j)}\right)^{\phi_j \xi_j}}, \frac{\prod_{j=1}^n\left(1+\log _r\left(1-\chi_\tau(j)\right)\right)^{\phi_j \xi_j}-\prod_{j=1}^n\left(1-\log _r\left(1-\chi_\tau(j)\right)\right)^{\phi_j \xi_j}}{\prod_{j=1}^n\left(1+\log _r\left(1-\chi_\tau(j)\right)\right)^{\phi_j \xi_j}+\prod_{j=1}^n\left(1-\log _r\left(1-\chi_\tau(j)\right)\right)^{\phi_j \xi_j}}\right)\\=\left(\frac{2(0.663)}{1.260+0.663}, \frac{1.168-0.798}{1.168+0.798}\right)\\=(0.689,0.188) $

Definition 6: Let $\left(\ell_j,\left\langle\mathrm{h}_j, \phi_j\right\rangle\right)(j \leq n)$ be IFNs, then the I-CLIFEHAGA operator can be mathematically expressed as:

$\text{I-CLIFEHGA}_{\zeta, \xi}\left(\left\langle \ell_1,(\mathrm{h}_1, \phi_1)\right\rangle,\left\langle \ell_2,(\mathrm{h}_2, \phi_2)\right\rangle, \ldots, \left\langle \ell_n,(\mathrm{h}_n, \phi_n)\right\rangle\right)$

\[ = \left\{ \begin{array}{c} \left(\frac{ 2\prod_{j=1}^n\left(1-\log_{r}\dot{\gamma}_{\tau(j)}\right)^{\phi_j \xi_j} }{ \prod_{j=1}^n\left(1+\log_{r}\dot{\gamma}_{\tau(j)}\right)^{\phi_j \xi_j} + \prod_{j=1}^n\left(1-\log_{r}\dot{\gamma}_{\tau(j)}\right)^{\phi_j \xi_j} }, \frac{ \prod_{j=1}^n\left(1+\log_{r}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} - \prod_{j=1}^n\left(1-\log_{r}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} }{ \prod_{j=1}^n\left(1+\log_{r}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} + \prod_{j=1}^n\left(1-\log_{r}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} } \right)\\ \text{where } r \neq 1 \text{, and } 0 < r \leq \min \left\{\dot{\gamma}_{\tau(j)},\left(1-\dot{\chi}_{\tau(j)}\right)\right\} \leq 1, \\ \left( \frac{ 2\prod_{j=1}^n\left(1-\log_{\frac{1}{r}} \dot{\gamma}_{\tau(j)}\right)^{\phi_j \xi_j} }{ \prod_{j=1}^n\left(1+\log_{\frac{1}{r}} \dot{\gamma}_{\tau(j)}\right)^{\phi_j \xi_j} + \prod_{j=1}^n\left(1-\log_{\frac{1}{r}} \dot{\gamma}_{\tau(j)}\right)^{\phi_j \xi_j} }, \frac{ \prod_{j=1}^n\left(1+\log_{\frac{1}{r}}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} - \prod_{j=1}^n\left(1-\log_{\frac{1}{r}}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} }{ \prod_{j=1}^n\left(1+\log_{\frac{1}{r}}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} + \prod_{j=1}^n\left(1-\log_{\frac{1}{r}}\left(1-\dot{\chi}_{\tau(j)}\right)\right)^{\phi_j \xi_j} } \right) \\ \text{where } r \neq 1\text{, and } 0 < \frac{1}{r} \leq \min \left\{\dot{\gamma}_{\tau(j)},\left(1-\dot{\chi}_{\tau(j)}\right)\right\} \leq 1 \end{array} \right. \]

In the context of vector representation, assuming two vectors $\lambda=\left(\lambda_1,\lambda_2, \ldots, \lambda_r\right)$ and $\xi=\left(\xi_1, \xi_2, \ldots, \xi_n\right)$. These vectors are associated with specific elements or entities, each having a corresponding vector representation. Additionally, there are weighted vectors, which can be represented as combinations of these associated vectors. The conditions for these vectors are as follows: both must belong to the closed interval $[ 0,1]$, meaning that each component of the vectors must fall within the range of 0 to 1 , inclusive. Furthermore, the sum of he components in both vectors must equal one. In simpler terms, the maximum value $\dot{h}_{\tau(j)}$ in the equation $\dot{h}_{\tau(j)}=n \lambda_j \mathrm{h}_j$ is influenced by a parameter called $n$. This parameter, referred to as the balancing coefficient, is a positive number. Essentially, the value of $\dot{h}_{\tau(j)}=n \lambda_j \mathrm{h}_j$ is determined and constrained by the value assigned to the parameter $n$. In essence, the balancing coefficient plays a crucial role in shaping the outcome of the equation, ensuring its effectiveness.

If $\lambda=\left(\lambda_1, \lambda_2, \ldots, \lambda_n\right)$ approaches to $\left(\frac{1}{n}, \frac{1}{n}, \ldots, \frac{1}{n}\right)$, then $\left(n \lambda_1\mathrm{h}_1, n \lambda_2\mathrm{h}_2, \ldots, n \lambda_n \mathrm{h}_n\right)$ approaches to $\left(\mathrm{h}_1, \mathrm{h}_2,\ldots, \mathrm{h}_n\right)$. In the IFEOWG system, the order-inducing variable is the element in the ordered pair $\mathrm{h}_j \in\left\langle\mathrm{h}_j, \phi_j\right\rangle$ that has the jth largest value. This specific variable plays a crucial role in shaping the overall sequence or ranking within the system. It significantly affects the prioritization process, contributing to the assessment of importance or weight in decision-making.

Decision-making is a systematic and methodical process that starts with recognizing a problem or seizing an opportunity. It involves gathering relevant information, analyzing available alternatives, and ultimately selecting the most suitable course of action. This structured approach is essential for individuals or organizations to make informed and rational decisions. This research focuses on decision-making processes dealing with complex polytopic fuzzy information, introducing techniques specifically designed for handling intricate data sets. These techniques are represented by operators, each serving a specific purpose. The paper emphasizes two significant operators: the I-CLIFEOWGA operator and the I-CLIFEHGA operator. These operators are tailor-made to address the complexities associated with intuitionistic fuzzy information, presenting unique strategies for decision-making in this specialized context. Let $\mathcal{B}=\left\{\mathcal{B}_1, \mathcal{B}_2, \ldots, \mathcal{B}_m\right\}$ be a finite set of $m$ alternatives. These could be different options, choices, or solutions that you are considering. $\partial=\left\{\partial_1, \partial_2, \ldots, \partial_n\right\}$ be a set of $\boldsymbol{n}$ criteria. These criteria represent the different factors or attributes that you will use to evaluate and compare the alternatives. Criteria could include things like cost, performance, reliability, etc., with a weighted vector $\partial=\left(\partial_1, \partial_2, \ldots, \partial_m\right)$. Let $E=\left\{E_1, E_2, \ldots, E_k\right\}$ be a set of decision-makers whose weighted vector is $\xi=\left(\xi_1, \xi_2, \ldots, \xi_n\right)$.

Step 1: In the first stage, the goal is to organize the information given by decision-makers in an intuitionistic, fuzzy environment. This involves using fuzzy numbers to capture the uncertainties and imprecisions inherent in the decision-makers' inputs. The objective is to develop a thorough and adaptable representation that considers the nuanced nature of the information provided by decision-makers.

Step 2: In the second phase, the goal is to form a unified matrix by merging distinct matrices through designated operations such as addition, subtraction, multiplication, or other pertinent actions, depending on the context. The value of each element in the resulting matrix is determined by executing the specified operation on the corresponding elements from the initial matrices.

Step 3: In the third step, the focus is once again on applying the suggested techniques or aggregation operators to calculate preference values. This step involves utilizing the proposed methods to evaluate and determine the preference levels for each option. The goal is to obtain a comprehensive set of preference values that will aid in making the best selection from the available choices. This process ensures that all relevant criteria and considerations are considered, providing a solid foundation for the final decision-making process.

Step 4: In the fourth step of the process, the objective is to give numerical scores to preferences, considering their significance in a specific context. This requires assessing and assigning values to preferences, allowing for a meaningful comparison and ranking. The aim is to create a quantifiable representation of how each preference influences the overall decision-making process within the given scenario.

Step 5: During the fifth step of the process, the focus is on assessing and sorting items according to the scores they've been assigned. The objective is to identify the item with the highest score, ultimately selecting or prioritizing it at the top of the ranking. This stage involves a detailed review of the given scores to make informed decisions about the order in which items are addressed or given priority.

Step 6: End of the algorithm.

Logarithmic aggregation operators are mathematical tools utilized in aggregating functions to combine values using logarithmic operations. They find applications across diverse fields like computer science, data analysis, and signal processing. These operators prove especially handy when dealing with multiplicative relationships, as they convert products into sums, thereby simplifying calculations. Their significance lies in decision-making processes where non-linear relationships are involved. Logarithmic aggregation operators help in normalizing scale differences, handling sensitivity towards extreme values, aligning with human perception, and offering flexibility in modeling various decision scenarios.
