Research of Collaborative Design Task Management Method Based on Grid

In the coordination design support environment full use network resources carry on the coordination work, realizes the different person to design the identical product together the goal. In the coordination design process, a complex task is decomposed to small sub-tasks with certain granularity and assigns each sub-task for in the suitable grid node completes by the suitable person. The entire product design process is one kind of lamination nesting structure, its design task decomposition is whether reasonable, will directly affect the product design flow and the design cycle, moreover the task coupling relations will involve the design change dissemination and the design recollection, therefore, will have to carry on the coordination and the control to each sub-task advancement, under certain rule control each task distribution for the different design personnel, will avoid as far as possible with the reduced coordination design process in the conflict, thus the guarantee coordination design overall task will complete smoothly. This article has studied the task theory of dissociation, has given the product coordination design task concrete decomposition method, uses the design structure matrix to judge the rationality which the task decomposes and to the task to carry on the reorganization, gives the coupling task collection the decoupling method. Finally, it has given the task plan function module network realization flow.
