Abstract

在自動化生產系統之中,能夠有效率地將必須的物料搬運至確切的地點,對系統所表現出來的績效有相當深刻的影響 吾人將在此研究多載量無人搬運車(AGV)在自動化生產系統的影響.傳統上,研究AGV系統的文獻大多是考慮單載量AGV系統(Unit-Load AGVs),當工廠需要較高的產出率時,為了滿足系統內大量工件的運送需求,有三個方法可以做為決策的參考:第一是增加AGV的速度,可是增加AGV速度,就安全理由而言,並不是一個可行的方式;第二為增加AGV的數量,雖然增加AGV數量是可增其負載的數量,但在傳統網路式佈置上,會使交通壅塞和碰撞問題更惡化;最後是增加AGV的負載量,即是使用多載量AGV系統(Multi-Load AGVs),增加負載量可改善車輛的使用率,以滿足運送需求並提高產出率。 因此吾人將以多載量無人搬運車作為自動化生產系統中的搬運工具,並且針對不同的載取派車法則(Dispatching Rule)及運送派車法則之組合下的設計,期望求得一個最佳化的法則組合,使多載量無人搬運車系統能發揮最良好的績效。 以下對載取派車法則與負載派車法則作簡單的說明: 1載取派車法則: 一台多載量AGV若決定其下一個主要作業為載取作業後,它立即會遇到的問題是該前往那個工作站載取工件,因此載取派車法則即為AGV用來判斷該往何處撿取工件的法則。 2.運送派車法則: 運送派車法則則是在無人搬運車在有承載工件的狀況下,決定出目前無人搬運車上所負載的工件中,哪一個工件必須優先送至下一個工作站。 In manufacturing system , it is very important to have a efficient material handling system , Tompkin and White(1984)ever point out that the cost of material handling is 20% to 50% of while manufacture operation. For this reason , we hope to design a good material handling system which can help to reduce the cost of manufacturing cost , we use AGV (Automated Guided Vehicle) to be transporting tools in our environment and control AGV with different rule included three dispatching or transporting choosing rules ,five dispatching rules ,eleven transporting rules. Finally ,we use simulation tool to show the results of combination of different kind of rules ,and hope to find the best combination.
