摘　　要：软件开发模型是对整个软件开发活动的总结,明确了开发活动步骤,用于指导软件开发。通过对瀑布模型、原型模型、增量模型和螺旋模型的研究,针对其局限性进行分析,发现其中缺陷,并提出一种新的软件开发模型——组合模型。该模型以增量模型为基本框架,添加了风险分析、专家知识库以及与测试有关的基本信息。将该模型在项目中验证,结果表明,该模型开发周期短,需要人力少,有效提高了软件开发效率,节省了大量人力、物力资源。The software development model is a summary of the entire software development activity.It clearly represents the various steps in the development activities and it guides the development of the software.Through analyzing the four traditional software development models-waterfall model,prototype model,incremental model and spiral model,especially for their limitations,the paper aims at the defects and puts forward a new software development model-portfolio model.This model takes the incremental model as the basic framework,adds basic information such as risk analysis,expert knowledge base,and test related content,and then applies the model to specific projects for verification.Practice shows that this kind of development model is feasible,and has a short development cycle and requires less manpower.It does effectively improve the efficiency of software development and saves vast human and material resources.
