摘要： 为了实现制造控制系统软件的有效重用,提出了制造控制系统软件构件的描述模型,保证软件构件描述与可执行代码之间的一致性。通过领域分析,将制造控制系统的软件构件接口与实现分离,信息与功能分离,构件之间通信通过独立的数据对象实现,消除了软件构件之间的网状调用关系,简化了应用软件结构和软件设计,提高了软件的可重用性和重用效率。

Abstract: In order to achieve an effective reuse of manufacturing controlling software, the paper proposes a description model for software component. It maintains the consistency of software specification and executive code. On the basis of domain analysis, software component interface and implementation are separated. The function and information are also separated. Communications between software components are fulfilled in manner of self-help data objects. The netlike call between components thus can be avoided. It could be predigested to design an application software system based on components. The components thus are more reusable.
