车间管理与控制重用类库的实现

面向对象的思想几乎涉及到计算机应用的各个领域，软件重用的研究当然不例外。软件的重用正从传统面向过程的部件重用（ＲｅｕｓａｂｌｅＣｏｍｐｏｎｅｎｔ）向类重用转移。要对类进行重用，就必须对已设计好的类有效的管理。因而，建立面向特定领域适合的重用的类库就显得尤为重要。本文在探讨重用类库的结构及管理的基础上，以车间管理与控制为应用领域，分析了其中类及类间的关系，以大型数据库ＯＲＡＣＬＥ为工具，实现了类库的管理。

Development of a Reusable Class Library for SFC

The concept of the object orient is so popular that almost all fields of the computer applications are involved, the research of reusable software filed is not an exception. The traditional way to develop software is oriented, the research of reusable software concentrated on the reusable component (a component oriented a special process), now it focuses on Object or Class. Only when we manage the object (Class) which has already well developed can we reuse it, so it is important to build a class library suited for reusing . The structure of a class library is analyzed firstly, then the basic function of the management of the class library is presented, finally, the realization on the class library using the Oracle database is introduced. And workshop management and control are presented, as an application domain.
