| Summary: | 碩士 === 國立中央大學 === 工業管理研究所 === 102 === In the past, most of the research in facility layout was focus on the closed-loop layout and linear layout. There was few study focus on “ladder layout,” even it is also one of the popular layout types in FMS. Therefore, a systematical procedure of building up the ladder layout is proposed in this study.
In the first stage, the similarity coefficient method is used to find out the best result of machine grouping. In the second stage, this study uses the technique of the flow line analysis, FLA, to arrange the machine groups. Then, a mathematic model is proposed to adjust the final point location of the each machine in its ladder level. In the end of the first two stages, the tabu search , TS, is introduced to improve the initial solution of each stage. There are four similarity coefficients and two clustering algorithms in the first stage and three heuristics in the second stage. All the combinations of the methods are experimented in FMS environment to show its performance and compared with the ones without improvement.
