程控交换软件设计的一种新方法

A New Approach to the Design of SPC Switching System Software

介绍程控交换软件面向对象设计（ＯＯＤ）方法的原理、特点、关键技术和原型实现。重点阐述并发对象的概念以及如何构造实时系统的并发对象模型，同时讨论对象划分、软件工程设计方法和ＣＡＳＥ（计算机辅助软件工程）工具选择等问题。

An introduction is given to the principle,features,key techniques and prototype implementation concenning the object-oriented design(OOD)approach to SPC switching systems. Emphasis is placed on the concept of coucurrent object and the modeling of realtime system concurrent objects. Object partition, software engineering design methods and CASE (computer-aided software engineening) tool selection are also discussed.
