在集成产品工程的框架下，提出了一种机械生产中产品成本估算的新方法。该方法引入了成本主体的新概念。这是必要的，因为目前的背景下，间接成本的增长，特别是在制造业。目标，即建立技术变量（或制造特征）和经济变量（建模为成本实体）之间的紧密联系，需要对与成本估算相关的推理程序和相关知识进行建模。为了实现这一点，提出了两个模型，一个产品模型和一个成本方案模型，并使用它们来表示和资本化技术知识。对考虑产品备选工艺方案的成本估算推理过程进行建模，并用约束满足问题求解。问题的解决方案按经济满意度排序。以Termoz零件为例，进行了制造实例说明。
A new approach for product cost estimating in mechanical production is proposed within the framework of integrated product engineering. The approach introduces the new concept of Cost Entity. It is made necessary due to the current context of growth of indirect costs, especially in manufacturing. The objective, i.e. establishing a tight link between technical variables (or manufacturing features) and economic variables (modeled as Cost Entities), requires to model the reasoning procedure and associated knowledge related to cost estimating. To achieve this, two models, a Product Model and a Costgrammes Model, are presented and used to represent and capitalize technical knowledge. The cost estimating reasoning procedure, that takes into account alternative process plans of a product, is modeled and solved by a constraint satisfaction problem (CSP). The solutions of the problem are ranked by economic satisfaction order. The case of a Termoz part is used as an illustrative manufacturing example.
