A Study of Product Development Time Based on Fuzzy Timed Workflow Net
It is necessary to find the relationship between product information and development process for saving product development time. Design information constraint tree (DICT) is proposed to describe the constraint relationships among multi-task information. Fuzzy timed workflow net (FTWN) is introduced to analyze product development time. An algorithm is proposed to map DICT onto FTWN. Task execution time and completion possibility are analyzed. The effectiveness of the proposed method to simulate product development time is validated by an example.
