In order to enhance the fixture board design efficiency and support fixture board original design, a framework method based on functional features was proposed. In this method, Functional Requirements (FRs) for the fixture board structures were analyzed. Through incorporating FR and Design Knowledge (DK) into the fixture board's Structure Features (SFs), the Functional Features (FFs) of fixture board...
It is time-consuming and complicated to complete aircraft product design which is one of the most important stages for aircraft development, the assistant knowledge management system for aircraft product design can help designers to reuse design experience and knowledge and to achieve rapid design. First, knowledge description and organization form are detailed. Then, the system design is described,...
Based on critical chain theory, a new method for aircraft development project was proposed on assembly task scheduling, which can effectively improve flexibility of assembly scheduling scheme. In the method, the priority rules for critical chain identification was established by the three characteristic parameters, and then the algorithm steps which identifies critical chain was listed by project...
This paper proposed a method of integrated progress control on aviation manufacturing projects. By analyzing the background of aviation manufacturing, the model of integrated progress control was presented, in which the indexes of the duration, cost and quality are integrated into scheduling plan. Based on the model, regarding Manufacturing Bill of Materials (M-BOM) as fundamental data source, the...
The expert judgment risks respond method used now in aircraft assembly project need to be improved for its subjectivity and complication. To make it more effective and reliable, we proposed an improved method that integrated neural network with framework reasoning. Firstly, basing on frame theory, we stored experts' experiences about risk response in the expert system repository by the rule that there...
