流程型生產系統中變動轉運批模式架構與模式解之研究

在流程型生產系統中，批量分割(lot-splitting)或稱批量流(lot-streaming)能有效縮短總製造時間(makespan)，綜觀過去批量分割相關文獻，以「變動轉運批」最能有效縮短總製造時間。有鑑於此，本研究在多階製程之流程型生產系統下，以總製造時間為評估績效，針對單產品「變動轉運批模式」架構作一完整之探討，此架構考慮以下三個議題：(1)決定轉運站(2)決定批量轉變範圍(3)決定最佳之批量分割，同時根據此模式架構提出最佳解(optimal solution)與探索解(heuristic solution)。經模擬驗證本研究所提之探索解優於其它現存之變動轉運批探索解。

並列摘要

Variable sublot models have received a lot of attentions [4, 23]. In this research, a model structure for variable sublots is proposed and analyzed for a single product in a multi-stage flow shop environment. The structure contains three issues as follows: (1) Determine transferring machines, (2) Determine the corresponding reallocated lot streaming ranges, and (3) Determine the optimal lot streaming. Based on the three issues mentioned above, optimal lot streaming is discussed. For computational efficiency, a heuristic solution procedure for the variable lot streaming is proposed. The proposed heuristic procedure is tested and evaluated via simulation. The results show that this heuristic procedure is better than other existing variable lot streaming procedures.
