First, study the concept and the key technology for dfc and analyze every factor influencing the products " cost within the products " life cycle ; second, set up the estimating model of products " cost based on the function to meet the modem products " design idea of the " top - down ", unifying the products " cost and structure on this functional concept ; third, based on the functionally estimating model of the products " cost, propose two grades of products " cost estimating method based on the function. the method can be used in the cost " estimation in the whole course of product design ; finally, regarding solidworks as the developing platform, delphi as the programming tool, structure a based on function - based products " cost estimating system to tentatively prove the practicability and feasibility of this text ' s estimating method
第一，研究面向成本設計的概念和關鍵技術，面向產品全生命周期分析影響產品成本的各項因素；第二，建立基於功能的產品成本估算模型，以適應「自頂向下」的現代產品的設計理念，將產品成本與產品結構在功能這一概念上得到統一；第三，在基於功能的產品成本估算模型的基礎上，提出了基於功能的產品成本兩級估算方法，此方法可用於產品設計全過程中產品成本的估算；最後，以浙江工業大學碩士學位論文摘要solidworks為開發平臺， delphi為編程工具，初步構建了基於功能的產品成本估算系統，驗證了本文估算方法的實用性和可行性。
