Task partition for function tree according to innovative functional reasoning

Task partition is a critical problem of collaborative conceptual design. Aiming at the shortage that current task partition methods don´t accord to innovative functional reasoning that is the kernel process and essence embodiment of conceptual design, a new task partition method for function tree according to innovative functional reasoning is proposed. To begin with, the concept of task module is proposed as the basic unit of task pre-partition before task module pre-partition algorithm that generates initial task modules is put forward. Furthermore, based on analyzing and gaining three basic constraint relationships: including, independent and innovative conflict relationship, M- TPG (module-driven task precedence graph) generated from the former two relationships is introduced into this field as the basic tool of task management. Lastly, task partition algorithm based on M-TPG with three basic principles for innovation is given. The new method is derived from clustering of microcosmic elements of innovative functional reasoning and conflicted task modules, which can obtain deeper cohesiveness and more reasonable results.
