This paper sustains a sound mathematical and computing background. In this paper, the software-based approach for solving intuitionistic fuzzy solid assignment problem (IFSAP) is presented. The IFSAP is formulated and it is solved by using Lingo 17.0 software tool. Theorems related to IFSAP is proved. The IFSAP and its crisp solid assignment problem both are solved at a time and their optimal solution is obtained. In addition, the optimal objective values of both the IFSAP and its crisp solid assignment problem (SAP) are estimated with the help of substituting the optimal solution(s) to their respective decision variables in the objective functions. Some new and important results are proposed. To illustrate the efficiency of the proposed method the numerical example is presented. The reliability of the proposed results are verified by using the numerical example. Strengths and weakness of the paper is mentioned. The novelty of the analysis is given into a coherent, concise, and meaningful manner of analysis. Social issue (real-life problem) is converted into a mathematical model and it is solved by the proposed method. At the end, the advantages of the proposed algorithm is explained.

Fuzzy Assignment problems

Profile image of Mohamed Muamer

In this paper, we deal with solving a fuzzy Assignment Problem (FAP), in this problem C denotes the cost for assigning the n jobs to the n workers and C has been considered to be triangular fuzzy numbers. The Hungarian method is used for solving FAP by using ranking function for fuzzy costs. A numerical example is considered by incorporating a fuzzy numbers into the costs.

To solve the problems of Engineering and Management Science Generalized Assignment Problem (GAP) plays a very important role. The GAP is a classical example of a difficult combinatorial optimization problem that has received considerable attention over the years due to its widespread applications. In many instances it appears as a substructure in more complicated models, including routing problems, facility location models, knapsack problems, computer networking applications etc. Recently, Fuzzy Generalized Assignment Problem (FGAP) became very popular because in real life, data may not be known with certainty. So, to consider uncertainty in real life situations fuzzy data instead of crisp data is more advantageous. In this paper, cost for assigning the j-th job to the i-th person is taken as triangular fuzzy numbers. Further we have put a restriction on the total available cost which makes the problem more realistic and general. The problem is solved by modified Fuzzy Extremum Diff...

This paper presents an assignment problem with fuzzy costs, where the objective is to minimize the cost. Here each fuzzy cost is assumed as triangular or trapezoidal fuzzy number. Yager’s ranking method has been used for ranking the fuzzy numbers. The fuzzy assignment problem has been transformed into a crisp one, using linguistic variables and solved by Hungarian technique. The use of linguistic variables helps to convert qualitative data into quantitative data which will be effective in dealing with fuzzy assignment problems of qualitative nature. A numerical example is provided to demonstrate the proposed approach.

I n the literature, there are various methods to solve assignment problems in which parameters are represented by triangular or trapezoidal fuzzy numbers. This paper presents an assignment problem with fuzzy costs, where the objective is to minimize the cost. Here each fuzzy cost is assumed as trapezoidal fuzzy number. A new ranking method has been used for ranking the fuzzy trapezoidal numbers. The fuzzy assignment problem has been transformed into a crisp one using ranking function and solved by branch and bound method. A numerical example is provided to demonstrate the proposed approach.

In this paper, we investigate an assignment problem in which cost coefficients are triangular intuitionistic fuzzy numbers. In conventional assignment problem, cost is always certain. This paper develops an approach to solve an intuitionistic fuzzy assignment problem where cost is not deterministic numbers but imprecise ones. Here, the elements of the costs (profits) matrix of the assignment problem are triangular intuitionistic fuzzy numbers. Then its triangular shaped membership and non-membership functions are defined. A new ranking procedure which can be found in [4] and is used to compare the intuitionistic fuzzy numbers so that an Intuitionistic Fuzzy Hungarian method may be applied to solve the intuitionistic fuzzy assignment problem. Numerical examples show that an intuitionistic fuzzy ranking method offers an effective tool for handling an intuitionistic fuzzy assignment problem.

    Subsections 2.4- 2.13 present the fuzzy arithmetic. Section 3 represents the formulation of FAP. Section 4 is devoted to present the proposed extended Hungarian method to FAP. In Section 5, two problems on fuzzy assignment problems are solved to demonstrate the efficiency of the proposed method. Finally, Section 6 presents the concluding remarks.

  21. [PDF] Solution of Generalized Fuzzy Assignment Problem with Restriction

    Cost for assigning the j-th job to the i-th person is taken as triangular fuzzy numbers and put a restriction on the total available cost which makes the problem more realistic and general. To solve the problems of Engineering and Management Science Generalized Assignment Problem (GAP) plays a very important role. The GAP is a classical example of a difficult combinatorial optimization problem ...

  22. (PDF) Fuzzy Assignment problems

    In conventional assignment problem, cost is always certain. This paper develops an approach to solve an intuitionistic fuzzy assignment problem where cost is not deterministic numbers but imprecise ones. Here, the elements of the costs (profits) matrix of the assignment problem are triangular intuitionistic fuzzy numbers.
