摘要

在多樣少量的產品需求環境下，生產系統中，單元製造為一不錯之選擇。在單元製造的分群研究裡，先考量產品與機器的關連性，進而考量訂單及機器使用率，再來考量單元內與間的佈置；然而同時考量單元的形成與單元間的佈置是較少的，此現象引起本研究的動機。
本研究擬建構一多期動態訂單與多行單元形成之生產佈置最佳成本模式，在多期需求變動環境下，考慮零件單元間與單元內搬運成本、機器固定成本、製造成本及重置成本，求解過程同時考量零件與機器的群聚形成及製造單元間的佈置最佳化。另在製造單元數量3、4與5三個範例驗證比較過程中，皆得到較低成本的機台選擇及佈置結果。最後，本研究針對零件搬運成本、零件批量大小、機器固定成本、機器製造成本與機器可用時間等進行參數之敏感度分析。相信本研究的成果能做為工廠在變動訂單環境下，單元間佈置最佳化之參考。

Cellular manufacturing systems are one of well-known and efficient approaches for the production environment with high variety and low volume products. In the clustering research, people first consider the correlation between product and machine, then consider the order and machine utilization, and then intra-cell and inter-cell layout, but there are few researches to consider cell formation and inter-cell layout simultaneously.
This research developed an optimization cost model of production layout with multi-period dynamic demand and multi-row. Under this dynamic demand environment, we considered intra-cell and inter-cell handling cost, machine fixed cost, machine manufacturing cost, and machine relocation cost. Besides, we verified the results in the case of three, four and five cells and got the lower cost of machine selection and layout, respectively. Finally, we had parameters sensitivity analysis with material handling cost, batch size, machine fixed cost, machine manufacturing cost, and machine available time. We believe that the results found in this study can be served as a reference for the optimization of inter-cell layout in the factory under the dynamic demand environment.
