Abstract :
In this paper, the delivery concept of an automated guided vehicles (AGV) used in TFT-LCD production lines are analyzed using Axiomatic Design Theory (AD). The main purpose of this paper is to elaborate how AD helped identify the problems in the current AGV system and how we applied AD Theory to redesign for a new system. We discovered that functional requirements in the current system are strongly coupled by the design parameters. Moreover, system performance was highly dependent on unpredictable and uncontrollable events. Based on the analysis, possible design directions for a new material handling are presented.
