摘　　要：订单式生产(Make To Order,MTO)人工作业系统(Manual Operation System,MOS)是我国中小制造企业广泛采用的生产系统模式。在MTO/MOS中,产品的质量水平与工人技能水平、工作态度、身心状态及公司激励、惩罚机制等密切相关。实际中,产品的生产需要经过部分人工工序。受人的技能等因素的影响,生产过程可能会产生一定比例的不合格半成品。考虑当各阶段的合格率分别为常数、服从离散随机分布、服从连续随机分布时,对其计划投产量及生产成本进行建模、求解及优化决策。理论及算例分析表明,当不同分布下同阶段合格率均值相等时,各阶段计划投产量及生产成本在连续随机分布下是最大的,而当合格率为常数时是最小的。对于离散随机分布,当其方差越大时,对应的计划投产量及生产成本也越高。MTO（Make-to-Order）and MOS（Manual Operation System）is the general production system mode of the small and medium manufacturing enterprises.About the production system,product quality closely relats to the worker skills,work attitude,work status,incentive and punishment mechanisms etc.In practice,several processes are mainly operated by men.Because of the influence of persons’ skills and so on,a certain amount of failed semi-finished products are likely to be produced.It considers when the qualified rate of each stage is constant,subjecting to random discrete distribution or continuous distribution,how to solve the problem of planning input quantities and corresponding costs of each stage with modeling and optimization decisions.The theory and numerical analysis shows that,as the qualified rates of the same stage under different distribution are equal,the planning input quantities and corresponding costs are maximum when the distribution is continuous,they are minimum while the qualified rates are constant.For the discrete distribution,as the variance is greater,the planning input quantities and corresponding costs is higher.
