| Summary: | 碩士 === 國立高雄應用科技大學 === 工業工程與管理系碩士班 === 95 === The golf club is fashionable sport apparatus that is used extensively, and the basic structure of a golf product includes the golf head, ferrule, golf shaft and the grip. The golf head, striking golf balls straight, is the most important part of a golf product, and its shape design, manufacturing methods and materials will influence the quality and cost of the golf product directly. At present, The golf head is mostly made of titanium, the manufacturing methods of golf heads mainly focus on precision casting. It goes several procedures that include metal pattern manufacturing, wax pattern injection, overhaul wax shells, wax tree assemble、slurry dip, dewaxing, casting, heat treatment, raw product modifying , polishing, art designing and packing. During the complicated productions, the relationship of every job flow might not be controlled correctly due to improper job flows, and might result in resource wasting, production cost increasing, production flows locking and business benefits decreasing because some working requirements and limited resources can’t be used efficiently.
The research object of this study is based on the production flows of a golf products manufacturing factory in southern Taiwan. During the procedure of golf club production, the system is due to improper processing procedure, mistake of mutual resource or planning schedule that result in productive procedure holding up, producing non-smoothly and delaying phenomenon. It uses step oriented transition Petri Nets, timed Petri Nets and continuous Petri Nets making a way of hybrid Petri Nets to carry out briefly description and detection, discusses the continuity, cyclic time and efficiency of production operation. That can monitor the production via Petri Nets with the production time of wax shells work station & cast work station of casting plant, eliminates unnecessarily wasting time, increases production efficiency and decreases production cost, and finds out the relationship of every working activity by the character of Petri Nets drawings to discuss the system efficiency. The precise casting procedure of golf club can be improved by Petri Nets drawings analysis. The productive efficiency of every golf wax tree assemble can be increased by 14.8%, every productive efficiency of raw product of golf club can be improved by 15.78%. That shortens the procedural time and reduces the productive cost.
