Material handling is critical in many facilities and manufacturing systems such as seaports, warehouse, TFT-LCD fabs, and semiconductor fabs. Among automatic material handling systems, AGVs is the most common because AGVs adapt easily to layout routes. Therefore, a lot of companies have utilized AGVs for material handling. Dispatching rule is essential to AGV’s transportation capability. Therefore, this study focuses on developing dispatching rules to dispatch AGVs. Three dispatching rules are developed for three different systems in this study. First, a Fuzzy Logic Control (FLC) is proposed for dispatching AGVs in a job shop environment. Second, a clustering-based method is proposed to solve two sub-problems of dispatching multiple-load AGVs, which are defined by Ho and Chien (2006), simultaneously. Third, a Fuzzy-Based Dynamic Bidding (FBDB) method is developed for dispatch AGVs to reduce the negative impact brought by hot lots in a TFT-LCD fab. Computer simulation is used to examine the proposed methods, and the superiority of the proposed methods is given by analyzing the results. Ying-Chin Ho 何應欽 2012 學位論文 ; thesis 95 en_US |
