| 摘 要： | 介绍了一些常用的估算软件开发成本的概念。成本估算主要有三种方法：专家判定法、类比法、参数模型法。软件成本估算有两个基本的策略：自顶向下估算、皂底向上估算。这些估算方法都依赖于历史数据，并且必须随着数据点的增加随时进行调整。基于已有的经验进行估算将获得更准确的估算结果。

| Abstract: | In this thesis we introduce some popular concept of cost estimation of software development.There are three main methods of cost estimation:expert method,analog method and parameters model method.There are two basic strategies of software estimation: from top to bottom,from bottom to top.All these three estimation methods depend on history dAtA,and must modify with the growth of data point.So based on those fact that already had happenod,will lead us to a more accurate result of estimation. |
