The introduced AGVS is dispatched by input and output thresholds imposed on the input and output queues of work stations. Threshold values are computed based on process time. The physical states of queues are detected by sensing devices and compared with thresholds to dispatch vehicles. Methematical model is defined to calculate required number of vehicles. Three guided-path models of AGVS are introduced: chessboard unidirectional, tandem bi-directional, and cyclic bidirectional guided-path models. Simulation models are established to perform system simulation for performance evaluation. Vehicle number is updated by analyzing the simulation results. Moreover, based on the performance evaluation, the best guided-path model should be adopted for actual system implementation.application/pdf88583 bytesapplication/pdfzh-TW國立臺灣大學工業工程學研究所無人搬運車及時生產拉式策略輸出入界限值系統模擬JITAGVSPull strategyThreshold valuesInventory及時生產環境下具輸出入界限值之無人搬運車系統規劃研究A Threshold Value Embedded Automated Guided Vehicle System for JIT Manufacturingreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/4169/1/872213E002033.pdf
