本文采用模糊线性回归模型，建立了产品成本与功能参数之间的函数关系，并根据产品的功能参数估计产品成本。通过实际计算，取得了满意结果，该模型可用于系列产品生产中新产品的成本估计。
In this paper, fuzzy linear regression model is used to establish the functional relationship between product cost and function parameters, and to estimate the product cost according to the function parameters of the product. Satisfactory results have been obtained through practical calculations. The model can be used to estimate the cost of new products in the production of a series of products.
