This paper describes the evolution of a production planning system (PPS) from a simple work sequence generation tool to a useful, sustained
scheduling system. Three stages of evolution are described. In the first stage, a Gantt chart sequencing tool was converted to a scheduler’s
information system. This change was driven by the need to support the scheduler’s daily task. The second stage of evolution was caused by an
MRP–ERP conversion. The integration and conversion increased overhead and complexity in the job task and hence the tool, including the
transformation of the previously integrated dispatching/scheduling task into separate dispatching and scheduling activities. The third stage of
evolution has been small continuous improvements driven by management reporting requirements. PPS was developed in 1996 and has been fully
operational since January 1997. Two major insights are discussed in this paper: the implications of supporting the scheduling task versus work
sequence generation, and the software design requirements for evolutionary change as the software is used in an ever-changing situation.

Answer 1

本文介绍了演化一条生产规划系统（聚苯硫醚） ，从一个简单的工作序列生成工具，以一个有用的，持续
调度系统。三个阶段的演进，都是形容。在fi道路安全组第三阶段则是甘特图测序工具被改建为调度的
信息系统。这一变化是由需要，以支持调度的日常工作。第二个阶段的演变而造成了
中mrp - erp的转换。整合和成果转化的增加开销和复杂性在就业工作，因此，工具，其中包括
转型以前综合调度/调度任务，纳入单独的调度和调度活动。第三阶段
演变已小，不断提升带动管理报告的要求。聚苯硫醚是发达国家在1996年，并已充分
业务自1997年1月。两个主要的见解进行了论述：所涉支持调度任务银两工作
序列生成，然后用软件设计要求进化改变，因为该软件是用在一个不断发展变化的形势。
