one of important problems in supply chains management is supplier selection. in a company, there are massive data from various departments so that extracting knowledge from the company’s data is too complicated. many researchers have solved this problem by some methods like fuzzy set theory, goal programming, multi objective programming, the liner programming, mixed integer programming, analyti...

The objective of the paper is to deal with a kind of possibilistic linear programming (PLP) problem involving multiple objectives of conflicting nature. In particular, we have considered a multi objective linear programming (MOLP) problem whose objective is to simultaneously minimize cost and maximize profit in a supply chain where cost and profit coefficients, and related parameters such as av...

Recently, the economic crisis has resulted in instability in stock exchange market and this has caused high volatilities in stock value of exchanged firms. Under these conditions, considering uncertainty for a favorite investment is more serious than before. Multi-objective Portfolio selection (Return, Liquidity, Risk and Initial cost of Investment objectives) using MINMAX fuzzy goal programmin...

Recently fuzzy interval flexible linear programs have attracted many interests. These models are an extension of the classical programming which deal with crisp parameters. However, in most real-world applications, nature parameters decision-making problems is generally imprecise. Such uncertainties can lead to increased complexities related optimisation efforts. Simply ignoring these considere...

The aim of this work is to establish a new methodology tackle the multi-objective transportation problems [MOTP] in Fermatean fuzzy environment that can deal with all parameters possess conflicting nature. In our research work, we developed score function context fermatean nature for converting data into crisp help technique. Then, introduced an algorithm-based methodology, i.e., Fuzzy Programm...

Abstract Electronic countermeasure (ECM) has become one of the most significant factors in modern warfare, course combat, electronic jamming allocation tasks need to be flexibly adjusted with change combat stage, which puts forward higher requirements for modeling and solution method this kind problems. To solve ECM dynamic weapon target assignment (ECM-DWTA) problem, a hybrid multi-target bi-l...
