近年來在彼此競爭激烈的大環境下,為了要達到降低生產成本和增加獲利能力,企業紛紛在生產流程、生產管理、人事、行銷等議題不斷精進,但是對於廠址選擇以及設施佈置卻是企業最早需要面對到的問題。隨著時間的改變,早期設施佈置問題都著重在相等部門面積上,而近代學者所探討的問題已逐漸轉向不等部門面積和不規則部門形狀,但是其廠房形狀設定絕大部分均為矩形,在實際廠房佈置上卻存在不合理的地方。因此本研究在此將對不規則廠房形狀的限制條件下進行設施佈置規劃,並以物料搬運成本最小化的計量資料為目標函數,以了解在廠房邊界的限制下部門佈置的方法。最後,在實際執行最佳化佈置時,本研究利用三種空間填滿曲線案例(X-Y混合掃描、X方向掃描、Y方向掃描)進行不規則廠房之案例分析,其結果顯示案例二(X方向掃瞄)、 案例三(Y方向掃描)在物料搬運成本上和案例一(X-Y混合掃描)相比降低了13.7%。
In recent years, enterprises always reinforce the portions of production process, human resource and marketing to reach the reduction of the cost and increase of the profit in the competitive environment. Facilities layout is the first problem that enterprise will meet. As the time changes, early facilities layout problems focus on equal area of departments, but recent researches turn to problems of unequal area of departments and irregular shape of departments gradually. In this research, facilities layout will focus on irregular shape of the plant, and set total material handing cost as the objective function. This research uses three cases of space filling curves in order to analyze the irregular shape facilities layouts. The result unveil the result that the total material handing cost of case2(X-oscillatory) and case3(Y-oscillatory) is lower than case1(XY-oscillatory) by 13.7%.
