Considering the hybrid nature of manufacturing systems where continuity and discreteness coexist, a hybrid analytic and simulation modeling approach for manufacturing systems using Arena, MATLABpsilas Simulink and Statflow is proposed. According to different simulation demands in different resolution level, the multi-resolution model is divided into three levels, so it can reveal both microscopic...
In order to implement flow management of process planning and meet the process informatization needs in manufacturing enterprises, application of workflow technology in process planning was discussed in this paper. The theory and modeling method of process planning based on workflow was studied, and the time model based on fuzzy timed Petri nets was set up, which analyzed time information of tasks...
The research presented the supply chain operation model based on networked manufacturing. It employs the Object-oriented Petri Net(OPN) to analyze the process of supply chain. The model of each object who takes part in supply chain operation was designed and the synthetical model was presented. Then, some properties such as deadlock, overflow and conflict can be analyzed. In such supply chain operation,...
The collaborative design is an important style for modern design. But the conflict appears in the process of design which may interface the design. Case-based reasoning (CBR) is a good method for conflict resolution, which has been applied in the artificial intelligence field successfully. However, due to the uncertainties in knowledge representation, attribute description, and similarity measures...
Partners selection and evaluation is one of the most vital actions of companies in a product design chain. Moreover, decision support is an important part of cooperative design. Selecting the right partner is the assurance of cooperative design. In order to improve reliability and scientificalness, a method of partner evaluation based on BP neural network and PCA is presented. An evaluation index...
