【摘要】：针对设计更改执行阶段效率的问题,从知识传递角度分析了设计更改执行过程中的知识流动机制,结合设计更改执行过程活动的离散并行性、逻辑时序性以及知识显/隐性转化特点,提出了基于改进时序Petri网的设计更改执行过程知识流建模方法和面向知识流分析的知识活动解构方法,建立了设计更改执行过程改进模型。提出了基于KFO-TPN模型的设计更改执行过程关键路径识别算法,以及基于语义信息增益和结构信息增益的设计更改过程知识流动合理性分析方法。以某研制型企业中设计更改单在车间内执行阶段的过程改进为例验证了所提方法的有效性。
[Abstract]:Aiming at the efficiency of design change execution, this paper analyzes the mechanism of knowledge flow in design change execution from the point of view of knowledge transfer, and combines the discrete parallelism of design change execution process. Based on the logic timing and the characteristics of knowledge explicit / tacit transformation, a modeling method of knowledge flow in design change execution process based on improved sequential Petri nets and a knowledge activity deconstruction method for knowledge flow analysis are proposed. A design change execution process improvement model is established. A key path identification algorithm for design change execution process based on KFO-TPN model is proposed, and the rationality analysis method of knowledge flow in design change process based on semantic information gain and structure information gain is presented. The effectiveness of the proposed method is verified by an example of the process improvement of the design change order in the workshop during the execution phase in a R & D enterprise.
