软件开发方法的几种过程模型研究

Study on Some Processing Models in Software Developing Method

良好的软件开发过程模型，对高效率、高质量和低成本地开发软件，具有重要的指导意义。本文介绍了软件过程模型的构造和特点．并从最传统的线性顺序过程开始，对瀑布模型、原型模型、演化模型、螺旋模型、RAD模型等模型的结构、特点作了具体的分析。

It is significant to the software development to create a favorable software developing processing model, which can improve efficiency and quality and lowness of the software development. This paper introduces the structure and haracteristic of software processing model simply and especial analyzes the structures and characters of some processing models waterfall model, prototype model, evolutionary model, spiral model, RAD model and etc beginning from traditional linear sequential process.
