Design And Implementation Of Workflow Time Management Based On Product Structure In PDM

PDM(Product Data Management) is the product throughout the life cycle of the product-related information managed by computer software. Time-based product structure management system is the core PDM functionality, this feature is to allow stakeholders to better grasp the progress of the project to improve production efficiency, reduce operating costs and enhance their market competitiveness.Time resources having such characteristics: 1, irreversible; 2, opportunistic; 3, the timing;4, rhythm. Irreversibility of time resources is an essential feature of time, but time will not reverse countercurrent only been carried out in the future; the timing of time resources, that maximum profitability, how to ensure get the best return in the same time frame. Sequential time resources, that enterprises in the production of the order to have time to grasp. Rhythm that is owned by the enterprise can play a good synergy between the value of the many resources.How to improve the efficiency and timely completion of the project schedule for enterprises of great significance in this study PDM echelon start, it will be time management as a core function to design, time management workflow, including the workflow process instance, set the initial state plan time, time monitoring node status and execution time constraint violation workflow adjusted to provide production efficiency and guarantee the orderly progress of the project will not be delayed.In order to achieve the actual production process for effective management of time and other resources, improve resource utilization, the paper Jilin University independently developed PDM system project background, workflow-based time management application of product structure in the PDM system were The main work content as follows:1. First introduced the background and the development status of PDM, the following describes the basic theoretical knowledge PDM, product structure.2. PDM product structure based workflow time management at the enterprise level, staff level and management level needs analysis, summarized as time settings, status monitoring,data analysis and statistics features three categories.3. After a needs analysis study WFMC workflow structural model, combined with PDM workflow model to design a complete product structure workflow time management solution theory model, including the model structure of the product design, and workflow time management model design.4. Time-based product structure workflow management system application results inPDM systems were displayed and analyzed by the implementation of the results showed that the application herein given to meet the PDM system in the workflow runtime to efficient management of time and other resources needs and have a good user experience.
