摘要

製造業為朝智慧工廠發展，以物聯網技術概念為基礎，發展出適合於工廠製造的網路實體整合系統，在未來的無人工廠，透過無線通訊設備，整合工廠內的無人搬運車與其他搬運設備，滿足生產所需的物料搬運。無人搬運車具有多種不同的控制方法以及各式各樣的硬體設備，企業必須按照自身的生產環境發展合適的無人搬運車系統，才能與同業競爭，從而達到永續經營的目標。
本研究目的在於結合網路實體整合系統概念與無人搬運車的控制方法，設計無人搬運車派車系統，以搬運車為主體進行搬運工作的協調與指派。本研究透過系統模擬的方法驗證所提出之無人搬運車派車系統，並透過實驗設計方法，探討在不同實驗環境下系統對各項績效指標的影響。結果顯示，本研究所提出的無人搬運車派車系統在工件平均等候搬運車時間以及搬運車平均利用率兩項指標有顯著且較佳的績效。進行多變異數分析，顯示本研究所提出的無人搬運車派車系統，對於各項績效指標的影響都為顯著。

Based on the concept of Internet of Technology, manufacturing companies have developed own suitable cyber-physical systems (CPS) towards the goal of smart factory. In the future factory, automated guided vehicle (AGV) and other transportation equipment will be integrated with wireless communication equipment, and this system will quickly fulfill the production needs. There are a variety of control methods and hardware equipment for AGVs, a company should develop a system according to its own production environment, and then the company may compete with other companies. Thereby the company could succeed in its field.

The purpose of this study is to design of an AGV dispatching system with combining the concept of CPS and dispatching rules of AGV, and the dispatching and coordination tasks in this system is AGV oriented. System simulation method was applied to verify the performances of the designed AGV dispatching system under different factor conditions with experimental designs. From simulation and ANOVA results, the performances of the designed system in average waiting time for AGV service and average utilization rate of AGV were statistically significant and better then another system. The results of MANOVA showed that the designed system were statistically significant in several performance indices.
