Introduction
Fuzzy logic is a powerful problem-solving method that encompasses estimation, classification, and decision-making [1]. It is based on fuzzy set theory, which is a generalization of classical set theory [2]. Fuzzy logic is known for its ability to handle incomplete and imprecise information, making it a more stable and flexible method compared to traditional logic [3]. This approach is particularly useful in various applications such as decision-making for sustainable transport [4], control systems for processes like distillation [5], and even in the field of health care for making value-laden choices [6]. Additionally, fuzzy logic has been applied in diverse areas such as corporate sustainability [3], accounting conservatism [7], and investment project assessment for sustainable development [8]. Despite its strengths, there have been concerns about the reliability of fuzzy logic, particularly in handling vagueness in language [9]. However, research has shown that when the available information for system modeling is imprecise and incomplete, fuzzy logic provides an excellent framework for system design [10]. Overall, fuzzy logic has proven to be a valuable tool in handling uncertainty and imprecision in various decision-making and control systems, making it a versatile and widely applicable method in diverse fields.

Understanding Fuzzy Logic
Fuzzy logic is an approach to problem-solving that deals with incomplete and imprecise information, making it a valuable tool in various applications. It is based on fuzzy set theory, which is a generalization of classical set theory, and allows for the handling of vague and uncertain information. Fuzzy logic is known for its ability to handle imperfect knowledge and quantify imprecise information, making it a flexible and stable method for decision-making and control systems. This approach has been widely applied in diverse fields such as cognitive wireless communications, heart disease diagnosis, power quality enhancement, and even in the development of autonomous navigation for mobile robots. Fuzzy logic provides a framework for asking human-like curiosity-driven questions over data and allows for the communication and understanding of large-scale visualization. It has also been used in the development of controllers for various systems, such as fluid level control, bioreactor processes, and power plant temperature monitoring and control. Fuzzy logic has been found to be robust but computationally intensive, and it has been applied to solve a wide range of problems, from image classification to test case prioritization in software engineering. Overall, fuzzy logic’s ability to handle uncertainty and imprecision makes it a versatile and widely applicable method in diverse fields, providing an efficient and effective approach to problem-solving[11].
Fuzzy Logic in Advanced Technology
The application of fuzzy logic is widespread across various advanced fields. In medicine, fuzzy logic is utilized for diagnosis due to the uncertainty and imprecision involved in ailment diagnosis. It is also employed in the development of cryptographic and steganographic techniques for selecting the best key and password and issuing random numbers from a Pseudo-Random Number Generator (PRNG). Additionally, fuzzy logic is applied in psychology for analyzing the psychology of adolescents using fuzzy logic analysis. In the field of music, it is used for creating music due to its importance in handling uncertain inputs. Moreover, fuzzy logic plays a vital role in image processing to deal with the lack of quality of an image or its imprecise nature. In robotics, an advanced fuzzy potential field method for mobile robot obstacle avoidance is proposed, demonstrating the application of fuzzy logic in this field. Additionally, fuzzy logic is used in geophysics for data inversion by clustering techniques to estimate the subsurface layer model. These examples illustrate the diverse and crucial role of fuzzy logic in addressing complex problems in various advanced fields[12-17].
