This paper deals with dynamic facility layout problem (DFLP) in a plant which is concerned determining the best position of machines during multi-period planning horizon. The material handling costs and rearrangement (MRC) are used to determine layout. In addition positions machines, details transportation such as type transporters sequence operations have direct effect on (MHC). Therefore, it ...

This paper presents ACO_GLS, a hybrid ant colony optimization approach coupled with a guided local search, applied to a layout problem. ACO_GLS is applied to an industrial case, in a train maintenance facility of the French railway system (SNCF). Results show that an improvement of near 20% is achieved with respect to the actual layout. Since the problem is modeled as a quadratic assignment pro...

For machining workshops that use automated guided vehicles (AGVs) for material handling and management, workstation layout AGV path are coupling factors affecting the cost (MHC). The multi-row is a typical pattern in many workshops, currently, there lack of studies on problem (MRLP) while taking into account path. This study established bi-objective optimization methodology integrating to minim...
