标题： Modèles de coûts en fonderie sable : les limites d'une approche générique

摘要： 在产品生命周期中尽快控制成本，成为公司在竞争普遍化背景下的一项主要竞争优势。 在提出与这种控制困难相关的問題之后，我们将介绍一种方法，该方法定义了一个与待设计和实现的产品活动相关联的成本实体概念。 然后，我们将尝试将这种方法应用于砂型铸造领域。 这项工作将突出由模型组成的实体的层级化困难以及通用方法的局限性。 显示英文摘要

摘要： The control of the costs, as soon as possible of the product life cycle, became a major asset in the competitiveness of the companies confronted with the universalization of competition. After having proposed the problems related this control difficulties, we will present an approach defining a concept of cost entity related to the activities of the product to be designed and realized. We will then try to apply this approach to the fields of the sand casting. This work will highlight the hierarchisation difficulties with the entities composing the models created as well as the limits of a generic approach.
