Study Of Conceptual Design Method Based On Demand Chain Product Model

As our country becomes a member of the World Trade Organization and as the situation of globalization economy comes into being, enterprises face a market with more intense competition. Only by enhanced its integrated strength enterprises can develop and exist under the new situation. Under the new market situation, rapid and high efficiency ability for new product design and development, dependable and steady product quality, nicer ratio of quality to price and satisfactory after services are all important factors that decide whether an enterprise can win in the market competition or not.Aiming at problems in new product development, integrating internal and overseas researches and developing trend and on the basis of deep analysis and research of customer demand, the dissertation puts forth a demand chain product model, based on which a product design method based on demand chain product model is put forth.On the basis of deep analysis and research of customer demand and product function, the dissertation puts forth an entity action description method to describe customer demand, gives definition and description of the entity, redefines demand and function on the base of entity. Based on which concepts of function-demand domain and function-demand group are put forth and with the concepts to analyze and deduce demand process, then the concept of demand chain is put forth and the dissertation points out that any product can be described with demand chain, demand chain is fundament of product structure. The dissertation analyzes how social work is divided and how product meets with customer demand, and puts forth a concept of social demand chain, so gives a new method for demand analysis of new product design and develop.Based on the concept of demand chain, the dissertation uses for reference of ideas of Value Engineering and Product Data Management, puts forth a new product model description method with demand chain product model; the dissertation abstracts entity with thought of Object-Oriented, puts forth a entity description method with entity model and puts forth a description method of demand chain product model with Single Layer Affiliations of Crunodes. With utility of Relation Data Theory, the dissertation constructs the data mode for product development with demand chain product model and givesa demonstrate to analyze the data mode. According to the developing trend of product design based Internet, the dissertation puts forth demand chain product model Internet design flat based on Virtual Private Network, and analyses system structure and safe problem of the net design flat.The dissertation gives an advice of constructing design information center, managing and maintenance great deal of design information with special organ and supply information service for product designer.Corresponding customer product design prototype system based on demand chain product model has been developed to prove the theory and method about product design the dissertation put forth.
