Abstract


Today, companies want to win in the competition in the market, we must quickly develop new products to meet market demands and changes, and to dominate the market as soon as possible. Product design and development has become a key link in the manufacturing industry to gain a competitive advantage. Due to the implementation of concurrent engineering, product development cycle can be shortened, improved product quality, product development costs can be reduced. At the same time, however, the product development process management becomes more and more complex, and more and more important. The parallel design process planning is concurrent product development process management in the most critical and the core of the. In order to make the parallel design process planning results more practical reference value, the traditional mandatory fragmented the decoupled strategy distortion without forced decoupling parallel design process planning. First research information flow dependencies between the impact of the implementation of the mandate, the deep-level mining interdependencies between design tasks; Then, in the traditional design process only on the basis of a modeling through the design task passed between the definition of the dependence of the flow of information, create a matrix of the information flow, the secondary modeling concept for the design process; through the analysis of the information flow matrix remodeling, draw current hierarchy of information flow, to take advantage of the design tasks and information flow relationship - Receive feedback to guide the implementation of the key design tasks, key design tasks in parallel design process without forced decoupling planning. In addition, forced decoupling planning on the basis of the design task from the perspective of closing conditions and completion of significance of the anatomical classification and coding design structure matrix and the information flow hierarchy delivery order relation matrix synchronous mapping obtained task segmentation matrix, adaptive subdivision of the design task and define the various types of sub-task execution priority; and then stream layer structure diagram and design tasks subdivision matrix synchronization mapping, building on a mission - information flow layer structure diagram, proposed a complete set of supplementary planning adaptive control task granularity to complete the remaining tasks in addition to key design tasks and subtasks, improve the entire design process in parallel task planning and optimization the planning results. Process planning, for example to verify the proposed set no the forced decoupling and adaptive granularity control concurrent product design process planning method in automotive general layout and planning of the traditional planning methods were compared, The results showed that: the sets method can effectively eliminate \according to the proposed set of parallel design process planning method, this paper also designed a set of concurrent product development process management system, and the parallel development process of planning a set-top box products, for example, to use the system to simulate the planning.
