| 摘 要： | 在定制改造开发过程中选择合适的原型系统,可以达到提高定制改造过程效率、减少开发成本、缩短开发周期的目的.在定制改造过程的原型分析和评估中依托构造成本模型COCOMO(COstructive COst MOdel) II,提出一种新的软件成本评估方法,综合分析了影响定制改造过程的功能差异、性能、规模、稳定性等关键因素,量化了这些关键因素对定制改造过程中成本计算公式中的关键变量--等价代码--的影响.实际的项目显示,该方法对预期工作量的估计误差约为17%,远小于COCOMO II模型40%的可接受阈值.

| Abstract: | Selecting an appropriate prototype for customized development process will increase development efficiency,decrease development costs and shorten development time.Based on the COCOMO(costructive cost model) II model,a new software cost assessment method was proposed to analyze the influence of the key factors,such as the function differences,system performances and scale,stability,in the development process.The influences of the key factors on the equivalent code,which is essential in the cost estimation formula,were quantified.A practical project shows that the assessment error is about 15%,well within the 40% acceptable threshold in COCOMO II model. |
