摘要：生产排程方案的优劣对MTO型企业的生产效率影响较大。为缩短订单的平均处理时间、提高订单准交率，依托于约束理论（TOC）和“简化鼓－缓冲－绳子”（S-DBR）方法，通过计算产能负荷率识别内部瓶颈，以提高订单准交率为目标，构建了基于S-DBR方法的订单排程计划模型。设计排程问题的遗传算法，对遗传算法的个体编码、交叉和变异等操作进行处理，并以某电子产品生产车间为研究对象进行求解。结果表明，与传统人工排程相比，该方法能有效缩短生产周期、提高订单准交率。

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
