| 摘 要： | 提出了一种适用于概念设计阶段成本估算的方法。首先提出了一个基于加权相似度算法的相似性度量模型，用来计算已知样本与待估算产品的相似程度，然后对样本与待估算产品的相似性进行分析，最后进行样本拟合，估算产品成本。来自真实系统的数据证明该算法优于其他算法，具有更高的精确度。

| Abstract: | A method for cost estimation in the period of conceptual design was presented in this paper. First a model based on weight similarity was proposed for measuring the similarity between the features of a sample and the product whose cost needed to be estimated. Then by analyzing the similarity and fitting the data, a result of cost estimation with good precision was obtained. |
