From a conventional mathematical programming model, and in accordance with which fuzzification is used, several models of fuzzy mathematical programming problems can be obtained. This paper deals with the study of the optimality concept for (g,p)-fuzzified mathematical programming problems. An auxiliary parametric mathematical programming problem is presented which allows the above model to be ...

Designing a logistic network is a strategic and critical problem that provides an optimal platform for the effective and efficient supply chain management. In this research, we address the application of fuzzy sets to design a multi-product, multi-period, closed-loop supply chain network. The presented supply chain includes three objective functions: maximization of profit, minimization of deli...

Assembly lines are often indispensable in factories, and order to attain a certain level of assembly line productivity, multiple goals must be considered at the same time. However, these may conflict with each other, this is multi-objective balancing problem. This study considers four objectives, namely minimizing cycle time, number workstations, workload variance, workstation idle Since object...

Fuzzy goal programming has important applications in many areas of supply chain, logistics, transportation and shipping business. Business management complications, there exist interactions between the factors its components. The locomotive world trade is maritime transport approximately 90% products are transported by sea. Optimization operations a challenge order to provide technical, operati...
