中文摘要：

选择合适的供应商并根据企业产品开发的需求确定其合适的参与时机和参与程度，是跨企业产品协同开发中供应商选择的关键问题。产品结构特征、企业资源和供应商资源的分类及其之间的关系是影响供应商参与时机和参与程度的重要因素。基于此，给出产品创新程度、零部件以及所需参与供应商的定义，提出基于“之”字映射的产品／供应商定义模型和算法。在综合考虑物料供应和新产品开发的基础上，从供应商满足和超越客户需求能力、参与开发风险及可信度四个方面定义了满意度、柔性度、风险度和信任度指标模型，并提出供应商选择的过程模型和方法。给出客车新产品研发过程中的供应商评估和选择的实例。

英文摘要：

It has been found that selecting proper participator to involve effectively in product development process at right time and to right extent is vital to the success of product collaborative development. The characteristics of product structure and the classification of resources and suppliers, and the relation between them are regarded as the main factors affecting the time and degree of supplier involvement. The definition of the degree of product innovation, the classification of components and involving suppliers are proposed. In order to find the relation between different types of components and involving suppliers, a mapping model and a design algorithm that describe the zigzag mapping process between product domain, decision domain and supplier domain are given. Considering the requirements of material supply chain and new product development, an index model including satisfaction, flexibility, venture and confidence indices for measuring the extent to which both the customer requirements and supplier capabilities match or mismatch is presented. The supplier＇s evaluation process and algorithm are proposed subsequently. Finally, an example of supplier selection in new carriage development is given.
