The task decoupling study on work breakdown structure of complex product

The coupled tasks of complex product may lead to iterations and iterative process and it would influence the quality and schedule of the complex product development. To achieve a reasonable planning about tasks, this paper works on the information transfer between measurable tasks to calculate the dependency degree on the basis of the variability and sensitivity, then construct a fuzzy dependency structure matrix to reflect the dependency of the coupled tasks. Then utilize matrix power to identify coupled task set, and decouple the coupled tasks. At last, this paper verifies this theory with instance.
