Research On Key Technologies Of Green Product Family Planning Driven By Variable Demand

With the development of manufacturing,mass customization has been widely used.Mass customization is a customer-oriented production model that requires businesses to respond quickly and accurately to different customer requirements.With the worsening of environmental problems,people's awareness of environmental protection gradually increased,and customer requirements evolved from traditional functional requirements and performance requirements to environment requirements.Proactively forecasting the customer environment requirements will be able to make rapid design decisions and responses to changes in product demand.The resulting green product family planning will be the key to implementing mass customization under changing customer requirements conditions.Therefore,this paper studies the key technologies of green product family planning driven by variable demand.The main contents are as follows.Analysis and prediction of customer requirements.Through the template of customer requirement gathering and BP neural network,the relationship between customer attributes and customer requirements has been studied,and the requirement information of specific customer groups has been obtained.In data-driven customer environment requirements forecasting method,ARIMA-SVM forecasting model is established to predict the customer requirements based on the analysis of product historical design data and historical sales data.According to the conflicting degree of coupling and the importance of the customer requirements,the priority of conflict resolution is determined and then the conflict existing in the customer requirements is solved by TRIZ method.Green product family plan driven by variable demand.The product family model is established through the multi-color set hierarchy,according to the forecasted customer's environmental requirements.The reasoning matrix in the product family model is determined by the coloring of polychromatic sets.The structural units and functional units of the product are configured to generate the green product family.So as to achieve customized according to customer requirements,rapid response to changes in customer requirements.Finally,taking mouse product as an example,the implementation of the method is illustrated.
