Research On The Truck Product Family Design Method Based On Mass Customization

At present,the domestic truck manufacturing enterprises are facing many difficulties and challenges.The general model marketing approach is not as successful as it was any more.To reduce product development cost and risk,domestic truck manufacturing enterprises need to change from mass production to mass customization production mode to provide more personalized and professional truck models with shorter delivery lead time.Traditional truck design process is not able to meet the requirement of mass customized production but customer need oriented product family design method is the key technology to manage the mass customized production.Product family design can support a series of products based on product platform and different function modules,which effectively meet each personalized customer need and accelerate the product development.This paper researches on the truck product family design method which expect to provide certain guidance in operation.First of all,the paper researches on the truck industry based on the theory of customer demand and analysis of the truck product definition and function characteristics.It studies the theories and methods of product family design,analyze the key technology of product family design types and elaborates the necessity and feasibility of product family design for truck.Secondly,in one business case study,by field investigation and the analysis of the semantic transformation,the paper builds the 4×2 medium-duty truck customer demand calculation model.With guidance from expert,it structures the function module of 4×2 medium-duty truck according to customer requirements and component coupling.With the improved QFD technology to analyze the customer demand weights,it also create 4×2 medium-duty truck product platform.Finally,according to the 4×2 medium-duty truck development example,the paper draws a truck main technical roadmap and the framework for product family design.It summarizes customer demand calculation model,modularization of product functioning and application of truck platform within product family design process for truck.It also put forward the collaborative design mechanism and the need of enterprise operational environment support on truck product family design method.In short,in this paper,the truck product family design provides the methods and reference for the truck manufacture to manage the mass customization production via 1.design of base types for truck product family based on modular design,2.customer demand calculation model and product function modularization and 3.using the improved QFD technology to develop the truck product platform.
