Improved Multi-objective PSO for Semi-desirable Facility Location Problem

Evolutionary optimization algorithms have been used to solve multiple objective problems. However, most of these methods have focused on search a sufficient Pareto front, and no efforts are made to explore the diverse Pareto optimal solutions corresponding to a Pareto front. Note that in semi-obnoxious facility location problems, diversifying Pareto optimal solutions is important. The paper the...

Solving the semi-desirable facility location problem using bi-objective particle swarm

In this paper, a new model for the semi-obnoxious facility location problem is introduced. The new model is composed of a weighted minisum function to represent the transportation costs and a distance-based piecewise function to represent the obnoxious effects of the facility. A single-objective particle swarm optimizer (PSO) and a bi-objective PSO are devised to solve the problem. Results are ...

An-Approach to Solve a Bi-Objective Un-Capacitated Facility Location Problem

A Cultural Algorithm Applied in a Bi-Objective Uncapacitated Facility Location Problem

Cultural Algorithms (CAs) are one of the metaheuristics which can adapt in order to work in multi-objectives optimization environments. On the other hand, Bi-Objective Uncapacitated Facility Location Problem (BOUFLP) and particularly Uncapacitated Facility Location Problem (UFLP) are a well know problems in literature. However, a few articles have worked in the sense of applied evolutionary mul...
