【摘要】 如何解决大型的复杂软件的可靠性及一致性问题是降低软件开发成本的关键。由此应运而生了许多计算机辅助软件工程(CASE)系统。本文将介绍我室汉化成功的大型软件工具CPSL/CPSA(Chinese Problem Statement Language/Chinese Problem Statement Ana-lyzer)系统,并摘要介绍如何应用该系统来描述一个目标系统。 CPSL/CPSA系统应用于软件生命周期的需求分析及设计阶段,其特点在于它提供了一个与自然语言类似的需求规范描述语言来描述目标系统,并具有对目标系统的描述进行分析、修改的能力,输出分析报告及自动生成文档。该系统应用于北京市蔬菜公司经济 信息管理系统的分析和设计,及石油部油藏模拟软件系统的分析、设计和文档生成,收到良好的效果。更多还原

【Abstract】 A key factor of reducing software development cost is how to improve the reliability and consistency of large and complicated software. Many CASE tools have emerged. This paper presents a large CASE tool called CPSL / CPSA (Chinese Problem Statement Language/ Chinese Problem Statement Analyzer) which was developed as a Chinese version of PSL / PSA. The paper also describes an example of using CPSL / CPSA in a target application.CPSL/CPSA has been used successfully in the "Computer-aided Economics and Information Management System" of Beijing Vegetable Corporation and the "Oil-deposition Simulation Software"of the Ministry of Petroleum of China.更多还原
