基于Petri 网的工业设计过程管理工作流建模研究

工业设计过程建模是产品设计过程管理研究的关键环节，直接影响着项目开发周期和整体效益，但目前工业设计行业没有针对设计过程管理有效的建模技术及其系统。为实现对工业设计企业设计过程动态性、结构性和有序性管理，在产品设计过程管理中引入面向过程的组织管理与流程优化的工作流技术及Petri 网建模方法；然后根据对设计过程管理流程的研究，构建了设计过程管理工作流程图；进而结合工作流技术、Petri 网过程建模方法和工业设计过程管理流程提出工业设计过程管理的4 个阶段工作流建模方法：本体分析、元素提取、元素概括、元素带入；最后，以工业设计过程管理建模领域为例构建了基于Petri 网的工业设计过程管理工作流模型，在此基础上实现了工业设计过程管理原型系统。

Workflow Modeling of Industrial Design Process Management Based on Petri Net

Industrial design process modeling is the key of product design process management study,which directly affects the development cycle and overall benefits of projects. However, there is noeffective modeling technology and system for design process management in current industrial designfields. In order to realize the dynamic, structural and orderly management of the design process ofindustrial design enterprises, we introduce process oriented organization management, processoptimization of workflow technology and Petri net modeling method in the product design processmanagement. Then, according to the research on the design process management process, the designprocess management workflow flowchart is constructed. In addition, combining with workflowtechnology, Petri net modeling method and the industrial design process management flow, this paperproposes a four-stage workflow modeling method for industrial design process management: ontologyanalysis, element extraction, element generalization and element introduction. Finally, based on Petrinet, a workflow management model of industrial design process management is built, and accordingly,the industrial design process management prototype system is realized.
