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...
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...
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...
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...
