Resource Management And Task Planning For Product Collaborative Development Chain

In the process of product development, the optimization of various design information and resources, and the coordination between manufacturer, customers and suppliers are widely applied as an important development mode. PCDC (Product Collaborative Development Chains) provides an effective method for this new development mode. Project-based PCDC is constructed to response the subdivision market demand through resource planning and optimum allocation of inter-enterprises. Therefore, how to organize, construct, optimize, coordinate and reconstruct the PCDC are the core research interests.The uniform description and management of collaborative development resource is the foundation of PCDC planning and implementation. So based on characteristics of collaborative development resource, a three-dimensional modeling structure is proposed and analyzed, including application module, life-cycle and resources classification dimensions. For the data consistency in collaborative development chains, PCDC resources are classified in terms of their property and character. And the logic structure model of PCDC resource information is also proposed.The main purpose of the components and suppliers management is to realize the effective utilization of the component and supplier resources. First, the relation among the suppliers is analyzed, which provides the basis for the different strategy of the suppliers' management. Second, according to the characteristics in the four different phases of PCDC life cycle, the corresponding processing flow of the suppliers' management events is also discussed. And the key technologies, such as resource search and security management for the management of the components and suppliers, are expressed and analyzed as follows.In order to make process of inter-enterprises complex product collaborative development go well, the effective matching between subtasks and suppliers should be realized by task decomposition and allocation. The process of task decomposition is analyzed and the relevant principles are proposed. The new product's design and manufacturing capacities of suppliers are measured and the feasibility of task decomposition is estimated using a proposed fuzzy matching methodology. The interaction and influence between sub-tasks are examined using the concept of influence and responsibility degree, at last, the task is decomposed into the independent sub-tasks set. Based on the collections of design sub-tasks and candidate suppliers, the impact factors such as product quality and cost etc. and the information and resource utility of supplier are considered synthetically, the optimal allocation model of design object are established. Based on the proposed task allocation strategy and principle, the corresponding algorithm is used for selecting proper designer or supplier for product development collaborative chain.Finally, based on ASP, SQL, the network platform of integrated management system for PCDC is proposed. In this paper, component and supplier management subsystem and task decomposition and allocation subsystem are designed. For component and supplier management subsystem, it has the function of component and supplier event processing on different stages of PCDC. And task decomposition and allocation subsystem can support complex product decomposition and corresponding subtask allocation function, as the operation platform of one-to-one correspondence between task and optimized suppliers.
