产品并行开发过程建模研究

并行工程的关键是对产品实行集成的并行开发,而产品并行开发过程模型是实现产品并行开发过程管理的 基础。本文从产品视图、功能视图、工作流程视图、组织视图、约束视图和资源视图多个侧面建立产品并行开发过程 集成模型,并详细研究了反映产品并行开发过程本质的组织视图、工作流程视图和约束视图模型的建立,建立了矩 阵式IPT组织模型以及产品并行开发工作流模型和多层约束网络模型。

Research on the Model of Product Concurrent Development

Product concurrent development is the key technology to implement Concurrent Engineering (CE), and the model of the process of product concurrent development is a precondition of product concurrent development management. In this paper, the process of product concurrent development is modeled in the views of product, organization, workflow, function, restriction, resource and the models of organization, and its workflow and restriction are studied in detail. IPT (Integrated Product Team) is a general organization for product concurrent development and it is modeled as a matrix. Meanwhile, the workflow is modeled as 8 steps, which are requirement analysis, conceptual design and evaluation, detail design, process planning, production preparation, production and check, product test, product delivery. The model shows that some of these steps can be carried out concurrently. The restrictions in concurrent product development, such as restrictions among IPTs, restrictions among engineers, restrictions among design parameters are studied and it is modeled as hierarchical network.
