The dynamic facility layout problem (DFLP) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. In this paper a new optimization algorithm inspired from colonizing weeds, Invasi...

In this paper, a new algorithm for solving the single loop routing problem is presented. The purpose of the single loop routing problem(SLRP) is to find the shortest loop for an automated guided vehicle covering at least one edge of each department of a block layout. First it shown that this problem can be represented as a graph model. Then a meta-heuristic algorithm based on and colony system ...

The problem of designing new keyboards layouts able to improve the typ-ing speed of an average message has been widely considered in the literature ofthe Ergonomics domain. Empirical tests with users and simple optimizationcriteria have been used to propose new solutions. On the contrary, very fewpapers in Operations Research have addressed this optimization problem. Inthis ...

Reconfigurable Manufacturing Systems (RMS) are designed to cope with mass customization problem. Assembly (RAS) a variant of this RMS concept in the assembly field. One most crucial issues designing RAS is layout problem human safety considerations. This paper’s main motivation propose methodology determine efficient and safe arrangement facilities workshop. The objective twofold: (i) minimize ...

A layout plan for a manufacturing system that is designed without any facility constraints will most likely be infeasible when confronted with reality. Additionally, considering land available building industrial plants limited and its cost high, it necessary to investigate the planning of two multi-floor facilities. To address these shortages in scientific literature, we focus on double-floor ...
