本研究係以電腦模擬應用於家具製程之改善，期能應用電腦科技於家具製造業，提升產業之效能，增加競爭力。研究中以製造中小學課桌椅之工廠為對象，先進行時間研究，分析其製程及工時，進而建立基本模擬模型，找出原製造流程之瓶頸，並提出改善製造流程，加以模擬，求得改善之成效。
綜合實驗結果簡述如下：
一、由馬錶測時法研究結果，課桌之加工標準時間為為23分44秒、課椅為26分50秒。
二、綜合各項改善方案可得，該工廠加工之主要瓶頸為榫孔及倒角處，經合併二相同尺寸之榫孔鑽鑿於雙軸角鑿機及增加倒角加工之人力，均可顯著提升產量。
三、「桌後腳1-1」之製造流程經工廠實際改善驗證之結果，與本實驗模擬所得結果相符。
應用電腦模擬，確定家具製程之瓶頸，並藉電腦快速運算能力，將不同家具製程之機械配置、工時進行模擬，可獲致良好效果；由研究結果可證實：模擬程式應用於家具生產流程之改變，具有足夠之信賴性，並可代表實際之結果；適當之生產線流程規劃是可以達成增加產量、減少成本之功效。

The main purpose of this study is to apply computer simulation to the improvement of furniture manufacturing process, with the expectation that we can apply computer technology to furniture manufacturing industry to promote the efficiency of production, and increase the competition ability. The object of this study is the furniture factories making desks and chairs for primary and high school. At first, we carried out the time study, analyzed the manufacturing flow chart and working-hour, and then built up the basic simulation model to find out the bottleneck of the original manufacturing flow chart, and brought up a better flow chart to simulate in order to achieve improvement. The experimental results are summarized as follows:
1.The result of time study by stopwatch method was the standard process time of a school desk was 23 min 44 sec, a school chair was 26 min 50 sec.
2.By synthesizing each improvement program we could get that: the major bottleneck of process in the factory was tenon hole and sanding angle, and we combined the two same tenon holes in a double-end mortiser and increased the manpower to sanding angle. Both of them could promote the efficiency of production.
3.The real factory operation result of the manufacturing flow chart “TBL1-1” was the same as the result of our simulation.
By applying computer simulation we could decide the bottleneck of the operation flow chart, and by the high-speed operation ability of computer, we could input different machine configuration of furniture manufacture to simulate the real operation in order to get better results; it could be proved by this study: it was reliable to apply simulation to furniture manufacture, which it reflected the real situation; the suitable operation flow chart could increase the efficiency of production and cut down the cost.
