订货生产式企业作业任务交货期决策研究

分析了工序时间的随机性特征及其对任务完工期的影响及作业任务交货期决策的重要性，确定任务交货期的方式，指出在工序时间随机性特征条件下，任务交货期应为一个区间，建立了以损失费用最小化为目标的最优交货期时区模型、最优最早交货期模型、最优完工时间偏差控制模型，采用计算机迭代法验证了上述各模型的有效性。

Due-Date Assignments for Make-to-Order Enterprises

This paper analyzes the stochastic features of operation,and its effects on completed time of job.Also the paper discusses the importance of due-date assignment and methods to predict completed time of job.On condition of stochastic features of operation,the due-date is a period of time.For the purpose of minimizing the cost of job,the paper develops some optimization decision-making models,such as the model of due-date of job,earliest due-date of job and standard variance of processing time control.The validity of those models is proved by computer iterative method.
