摘要

家具工業之製程所需之加工零組件，有時相當多且富變化；大多數工廠為訂單式生產，因此對各種生產計劃之日程安排，如何能夠把握經濟性生產，並建立一套快速，準確的評核系統，日趨重要。由於16位元微電腦之應用日漸普遍，以培基（Basic）程式語言之計劃評核術RERT（Program Evaluation and Review Techniqne）程式處理家具生產之網路（Network）分析，能迅速獲得準確的結果。本研究選用生產較為普遍之咖啡桌為對象，在五家工廠分別進行標準工時測定，所得資料經程式分析結果，要徑路線為①→②→⑥→⑩→⑬→⑯→⑰→⑱→⑲，且以C廠之生產效率較高；網路分析之結果，將可提供管理者作最佳的日程設計。利用群組生產之方式，可使製程之餘裕等待時間減少，全程作業時間減少15.4%，而使生產效率提高16.0%之多。這些研究成果將可作為家具生產業者嘗試進行生產計劃擬定之參考，將使生產管理更趨合理而完善，提昇現有工廠之競爭力。

The process of furniture manafacturing involves many kinds of items, including subassemble and assemble operations. Most of them are intermittent processes and change the model so frequently. Therefore how to establish a rapid precise evaluation system for process control, and how to produce the Whole-parts economically are very important today. By the application of the Program Evalvation and Review Technigue (PERT) of the Basic program language, equipped with 16 Bits microcomputer, a rapid and precise result pertaining to the network analysis of furniture manufacturing can be obtained. Cocktail table is one of the most popular furniture items produced in Taiwan, so it was chosen as the investigating object in this study. The standard working time was measured by time study method in five different plants which produced cocktail table. Then input those data into 16 9its microcomputer for PERT analysis. After analysis of data the critical path is shown as follow: ①→②→⑥→⑩→⑬→⑯→⑰→⑱→⑲, and plant C was shown as the most efficient plant. From the results of network analysis, we can easily get the best solution of scheduling by using the efficiency evaluation technique. Using the group technology as a tool for process control, it was shown that the slack waiting time could be reduced while on the production line, whole working time could be decreased by 15.4%, thus it created the production efficiency up around 16.0%. The results of this study will provide a guideline for production planning when the manufacturer tries to initiate a furniture production plan: Due to these advantages, it would help us to establish a new rational and complete management system to improre the competitive ability of present plant.
