Abstract


With the deepening of the theoretical research of computer network technology widely used with modern design, the traditional product design method based on serial design patterns increasingly unable to adapt to the needs of the enterprise product innovation design. Product innovation and design capabilities of modern enterprise core competitiveness, only with innovative products designed to enable enterprises to win in the fierce competition in the global market. How to enhance product innovation and design capabilities, has become a widespread concern of today's product manufacturing enterprises and research institutions. At present, the modern design theory and computer network technology combined global product design, manufacturing, research institutions, widespread concern based on distributed collaborative design of heterogeneous network environment, become a hot research field of networked manufacturing. Networked collaborative product design is a collaborative product design process as the research object, emphasizing the design process, design resources optimization configuration and sharing to improve design efficiency and shorten the development cycle, the goal of enhancing the competitiveness of their products. Network product collaborative design of a computer-supported cooperative work in the field of modern product design mode. Currently, the network product collaborative design research focuses on networked collaborative design of intelligent technology research, support knowledge integration and management of networked collaborative design model, network collaborative design process modeling, control methods and strategies to support collaborative awareness research, research-based project management and workflow technology networked collaborative design management, networked collaborative design support platform environment. In this paper, for the network product collaborative design process management task decomposition, allocation study. Thesis work is mainly reflected in: a collaborative design task decomposition and coupling mechanism, to adopt collaborative product design task decomposition by function and the combined structure is divided, and according to the satisfaction of the design group, using numerical design modeling structural matrix of the design task, given Coupled task set is obtained based on the adjacency matrix of the depth-first search algorithm using graph theory, and validated through examples. Collaborative design tasks allocation strategy with the task to select the matching algorithm, the use of economic behavior in the bidding contract net mechanism, based on contract net task allocation model, in order to adapt to the dynamic allocation of collaborative design tasks, task allocation analysis of the factors, and the factors that affect the distribution of tasks selected. Index based on two factors of the Task Force and design group, collaborative design tasks assigned choose the matching algorithm. Based on the above theoretical research collaborative design task decomposition, distribution and management system design, the B / S mode, using Java, Oracle development environment, to achieve a system of project management, personnel management, task decomposition, task allocation, and data browsing features such instances running on various functional modules, verify the feasibility and effectiveness of the prototype system.
