It is extremely important for effective control and management of process planning, but there are many shortcomings with traditional process planning system in these aspects. To solve these problems and meet the process informationization requirements in manufacturing enterprises, application of workflow technology in collaborative process planning system was discussed. Semantic decriptions of workflow...
Aimed at security issues in collaborative process planning system, a multi-level and dynamic access control (PPMLDAC) model was proposed for collaborative process planning based on role based access control (RBAC) model. A multi-level permission model was discussed on the basis of product and task decomposition level structure. New concepts of permission and permission assignment were defined for...
The paper proposed a new thought that a multi-agent organization model was designed, which based on cooperative design system network framework and workflow. The system workflow and system architecture were presented. The ant colony optimization (ACO) method which was improved by Bayes was applied to the partner selection. And the principal component analysis (PCA) method was used to evaluate the...
Collaborative design is a new technique for mechanical design. Multi-agent system (MAS) can cooperate with others to solve problems by network of software agents. Collaborative design system includes design agent, manage agent, conflict resolution agent and so on. A method based on MAS is present to solve the resource finding among agents. Firstly, the relationship between multi-agent systems and...
Collaborative design is a new design style for mechanical manufacture, which is an important means in networked manufacture. Designers work at the same time will encounter the conflict, which should be solved. Firstly, the class of conflict is addressed to make a basis for conflict resolution. Then the conflict resolution method is applied. The resolution model is set up. According to the conflict,...
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...
Collaborative process workflow is able to implement effective control and management for process planning flow and meet the process informationization needs of manufacturing enterprises. With the application of stochastic Petri nets (SPN) to the model of collaborative process workflow, the article proposes the method of collaborative process workflow modeling. The relationship of actual process flow...
