This paper investigates a multi-period rectilinear distance 1-center location problem considering a line-shaped barrier, in which the starting point of the barrier follows the uniform distribution function. In addition, the existing points are sensitive to demands and locations. The purpose of the presented model is to minimize the maximum barrier distance from the new facility to the existing ...

We study various models for the one-dimensional multi-stage facility location problems with transient agents, where a agent arrives in some stage and stays number of consecutive stages. In problems, we need to serve each one their stages by determining at stage. first model, assume there is no cost moving across focus on optimal algorithms minimize both social objective, defined as total distan...

The unequal area facility layout problem (UA-FLP) refers to the reasonable arrangement of a certain number facilities in given area. should satisfy constraints and optimize optimization objectives as far possible. In this paper, method combining improved lowest horizontal line particle swarm algorithm is proposed solve UA-FLP, which achieves multi-objective material handling cost, adjacent valu...

This paper addresses optimization of multi-objective facility layout problem. Facility layout plays a key role for companies, and it is an inseparable part of the manufacturing system design process. Traditionally there are two approaches to the facility layout problem. One is the quantitative approach aiming at minimizing the total material handling cost and another is qualitative approach aim...
