Several scholars defined the concepts of fuzzy soft set theory and their application on decision-making problem. Based on this concept, researchers defined the generalised fuzzy soft set and its applications. However, to the best of the author’s knowledge, the generalised fuzzy soft set has not been dealing with in the generalised fuzzy soft code set. In this paper, we introduce the notion of generalised fuzzy soft code set and its application.
The theory of fuzzy soft sets and its application, generalised fuzzy soft sets and fuzzy codes in different years were studied with various researchers. To derive a generalised fuzzy soft code set, we apply the concepts of generalised fuzzy soft set and a new view of fuzzy codes and its application. A new aspect of this paper is to introduce the definition of generalised fuzzy soft code sets and its application on medical diagnosis and decision-makings.
Generalised fuzzy soft code is the most powerful and effective extension of fuzzy soft sets that deal with the choice’s parameterized values. It is an extended model of fuzzy soft sets and a new mathematical tool with significant advantages for handling uncertain information and is proposed by combining the concept of fuzzy soft sets and fuzzy code sets. This paper introduces the concept of generalised fuzzy soft code and its properties.
In this study, we combine generalised fuzzy soft set and a different approach to coding theory to introduce generalisation of fuzzy soft codes. The paper also considers the relation between generalised fuzzy soft code and its application. We discussed the matrix representation of generalised fuzzy soft code. Furthermore, a demonstration example illustrates how the strategy could be effectively applied to various problems.

Zadeh (1965) established the notion of a “fuzzy set” as a way to represent a class of objects with different membership grades. A membership function, also known as a characteristic function, describes such a set, with each item’s membership degree ranging from 0 to 1. Molodtsov (1999) presented the theory of soft sets as a novel mathematical technique for handling uncertainties that are outside the scope of current mathematical techniques. In order to address complicated issues including ambiguity and uncertainty, Molodtsov created a universal mathematical tool that may be applied to both conventional and some modern mathematical methods. Fuzzy sets are conceptualized in a way that makes their methods intuitively clear. Maji, Biswas, and Roy (2003) developed the theory of soft sets. Gogoi, Kr. Dutta, and Chutia (2014) introduced an application of fuzzy soft set theory in day to day problems; Roy and Maji (2007) presented the application of fuzzy soft set theory to decision-making problems. Amudhambigai and Neeraja (2019) discussed a new view of fuzzy codes and its application. Ozkan and Mehmet (2002) introduced different approaches of fuzzy codes and their properties. Malik, Mordeson, and Nair (1992) defined the concept of a fuzzy generating set and describe the fuzzy subgroup which it generates and introduced the notion of a minimal fuzzy generating set. Ali et al. (2018) designed and develop a new class of linear algebraic codes defined as soft linear algebraic codes using soft sets. They also discussed some algebraic properties of soft codes. Garg and Arora (2018) describe the concept of generalized IFSS. Kong, Wang, and Wu (2011) studied the implementation of grey theory-based fuzzy soft sets in decision-making situations. Lin et al. (2018) a set of code words from the cyclic code are decoded using a binary parity-check matrix in a soft-joint manner. Gereme, Demamu, and Alaba (2023), Hamming distance of fuzzy codes and other features of binary fuzzy codes. (Lin et al. 2018) a novel coding technique for the Galois-Fourier transform domain that is intended for collective encoding and collective iterative soft-decision decoding of cyclic codes of prime lengths. Kamble (2017) examined the codes that emerged from soft sets and fuzzy sets, and using fuzzy linear space, explained the properties of fuzzy linear codes. Kim (2023) developed a fuzzy linear code description based on linear algebraic codes. Tsafack et al. (2018) established the concepts of fuzzy cyclic and linear codes over a Galois ring. Majumdar and Samanta (2010) established generalized fuzzy soft sets and investigated a few of their characteristics. It has been demonstrated that generalized fuzzy soft sets can be used to diagnose medical conditions and decision-making problem. Adde, Toro, and Jego (2012) examined linear block code of maximum likelihood soft-decision decoding. Dauda, Mamat, and Waziri (2015) an application of fuzzy soft sets based on a thorough theoretical analysis of the fundamental operations of soft sets and a definition of soft sets. Kané (2021) suggested a different method for figuring out the fuzzy optimal solution to a semi-fully fuzzy linear programming issue. Ali et al. (2023) discussed the generalized intuitionistic decision-theoretic rough set, a combination of intuitionistic fuzzy sets and decision-theoretic rough sets.
However, as far as the author’s awared, no studied pertaining to the fundamentals of generalised fuzzy soft code have been released. Thus, motivated by the formationed works, the current study seeks to introduce this idea. To derive a generalised fuzzy soft code and its properties, we integrate the concepts of a generalised fuzzy soft set (Majumdar and Samanta 2010) and a different approaches of coding theory (Ozkan & Mehmet 2002). A new aspect of this paper is to introduce and develop the definition and application of generalised fuzzy soft code by combining the concepts of fuzzy soft set and fuzzy codes. The definition and features of relations on generalised fuzzy soft codes are proposed.
The organization of this study as follows: Section 2 included fundamental notions and properties of preliminary concepts, Section 3, Generalised fuzzy soft code, and some of their characteristics, whereas, Section 4 takes into consider relation on generalised fuzzy soft codes and its application.
In this section, we review a few fundamental concepts that we utilize to get our outcomes.
Ozkan & Mehmet (2002) The notion is a q-ary code which is a collection of symbol sequences in which each symbol is chosen from a set of q different components. The set is sometimes referred to as the alphabet and is defined as the set

Where each p i in . The elements of are referred to as words or vectors.
Ozkan & Mehmet (2002) Let us assume that has as a code word. The relative weight of a code word denoted as

(Amudhambigai and Neeraja 2019) For any fuzzy code , the complement is is calculated by subtracting from 1 the relative weight of each member of .
(Kong, Wang, and Wu 2011) Consider the idea of a set of parameters represented by and be the notion of a starting universe of items. be represents the power set of and . A pair is a soft set over if and only if is a mapping given by
In other words, the soft set is a parameterized family of subjects from the set U.
Consider the set of elements of the set , or the set of approximate components of the soft set, where can be arbitrary, some of which can have nonempty intersection, and some of which can be empty. This applies to every F (e) from this family for e in . where the attributes, traits, or properties of objects are usually the arguments. We might consider Zadeh’s fuzzy set as a subset of the soft set. Given a fuzzy set , its membership function is , that is, μ A is a mapping from into that is

A generalised fuzzy soft set (in short GFSS) over the soft universe is then denoted by . Here, for every parameter , showed both the degree of belongingness that represents and the degree of belongingness of the elements of in

If and represent any GFSC over a shared soft universe , then the following result is hold:
The proof follows directly from the definition.

The following illustrates how this generalized fuzzy soft code relation is used in a decision-making problem. Assume there are four computers in the universal set

In order to identify the optimal computer, we first identify the greatest numerical grade indicated by the parenthesis in each column, with the exception of the final row, which represents the computer’s grade of belongingness in relation to each set of parameters. Now, the total of the products of these numerical grades with the associated values of is used to calculate each of these computers’ scores. That is the desired computer, the one with the greatest score. We do not take into account the computers’ numerical grades in relation to the pair as both the parameters are same.
Hence, score

The company will then choose the computer that scored the highest, and they will purchase that computer

In fact, in this study, we introduced binary fuzzy soft code and its properties, and an application of Generalised fuzzy soft code has been presented. This study will serve as an introduction for future researchers who will work in this area. Furthermore, we can develop the study of Generalised interval-valued fuzzy soft codes; generalised intuitionistic fuzzy soft codes; Generalised interval-valued intuitionistic fuzzy soft codes and other related topics, are possible in future works.
