Research on task scheduling in concurrent design

Reasonable task scheduling is the first step in planning product concurrent design process. Considering the characteristics of task scheduling in concurrent design, the relevant factors and constraints in enterprises, the method for constructing fuzzy design structure matrix was provided based on fuzzy sets theory. The scheduling algorithm of design tasks in coupling task collection based on Task Influence Degree was put forward. After taking factors of dynamic, fuzzy, non-quantification about subtasks and team members into consideration respectively, the balanced matrix among subtasks and team members was established. Integrating Hungary Algorithm and Genetic Algorithm, the models and algorithms of task assignment from subtasks to team members were given according to different conditions.
