摘要：生產排程方案的優劣對MTO型企業的生產效率影響較大。為縮短訂單的平均處理時間、提高訂單準交率，依托于約束理論（TOC）和“簡化鼓－緩沖－繩子”（S-DBR）方法，通過計算產能負荷率識別內部瓶頸，以提高訂單準交率為目標，構建了基于S-DBR方法的訂單排程計劃模型。設計排程問題的遺傳算法，對遺傳算法的個體編碼、交叉和變異等操作進行處理，并以某電子產品生產車間為研究對象進行求解。結果表明，與傳統人工排程相比，該方法能有效縮短生產周期、提高訂單準交率。

關鍵詞：TOC；S-DBR；生產排程

Abstract：The quality of production scheduling scheme has a great impact on the production efficiency of MTO enterprises. In order to shorten the average order processing time and improve the order delivery rate, relying on the Theory of Constraint (TOC) and the “Simple Drum-Buffer-Rope” (S-DBR) method, the internal bottleneck is identified by calculating the capacity load rate, and the order scheduling model based on S-DBR method is constructed to improve the order delivery rate. In this paper, a genetic algorithm for scheduling problem is designed, the individual coding, crossover and mutation of genetic algorithm are processed, and an electronic product production workshop is taken as the research object to find the solution. The results show that compared with traditional manual scheduling, this method can effectively shorten the production cycle and improve the order delivery rate.

Key words：TOC；S-DBR；production scheduling
