We develop an algorithm for the solution of multiobjective linear plus fractional programming problem (MOL+FPP) when some of the constraints are homogeneous in nature. Using homogeneous constraints, first we construct a transformation matrix T which transforms the given problem into another MOL+FPP with fewer constraints. Then, a relationship between these two problems, ensuring that the solu...

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...

Facility layout planning is an indispensable part of the manufacturing and service operations. In literature, there are two main different approaches for solution facility problem: While first one aims to minimize both total transportation assignment costs in a quantitative way, second maximize closeness relationship more qualitative way. this study, we use these model multi-objective optimizat...

In this paper fully fuzzy linear programming (FFLP) problem with both equality and inequality constraints is considered where all the parameters and decision variables are represented by non-negative trapezoidal fuzzy numbers. According to the current approach, the FFLP problem with equality constraints first is converted into a multi–objective linear programming (MOLP) problem with crisp const...
