摘　　要：铸造的工序多,周期长,面向订单生产,信息化水平相对较低等特点,导致铸件生产工期管理困难、铸造企业按时交货率普遍较低,而目前学术界和企业界对此均缺乏良好的应对措施。本文分析了工期控制的意义,并将其划分为工期预警和工期预计两部分;提出了工期盈余期模型,该模型包括工艺盈余期和当前生产盈余期两部分;开发了工期预警和预计系统,并在某铸造企业应用。应用表明,该系统能明显改善企业的按时交货情况。With many processes,a long production cycle,making to order,relatively lower information level and so on,foundry enterprises have difficulty in managing duration of castings,and their on-time delivery rate is generally low,while there are no good corresponding measures in the academia and industry.This paper analyzed the significance of the duration control that was divided into two parts,namely the duration of early warning and prediction.A duration surplus model was proposed,which contained the technology surplus period and the current production surplus period.The system of the duration of early warning and prediction was developed and applied to a foundry enterprise.The application shows that the system could obviously improve on-time delivery of the enterprise.
