Research On The Optimization And Effect Evaluation Of NPD-oriented Purchasing Process

Under the environment of increasingly fierce market competition and rapid technological transformation,enterprises need not only to development new products to respond to market demand quickly,but also to focus on new purchasing methods to support new product development.Purchasing involvement in new product development has become a new collaborative way of product development.As the interface for logistics and information between internal R&D and external suppliers,purchasing provides external material resources and information technology for the new energy automotive enterprises.Also,the participation level of efficiency and process management has undeniable effect on the overall performance of new product development projects.However,the process management of such activities has not got enough attention.Due to the fact that material requirements are always purchased with characteristics of small volume,low frequency and high uncertainty in the new products development,it is difficult for the existing methods of process optimization to effectively and efficiently coordinate the NPD-dominant enterprises and suppliers to jointly improve the new product development performance.In this thesis,the optimization and effect evaluation of NPD-oriented purchasing process in new energy vehicles enterprises is taken as the research object.First of all,through review of related theories like purchasing involvement in new product development and business process optimization systematically,the thesis finds out shortcomings of the current research.Then,based on the responsibilities and tasks of purchasing in the different stages of new product development,adjust the purchasing process suitable for the situation of new product development.Also,optimize the implementation steps of optimization process which is designed by theoretical analysis.Thirdly,the two systems of the process optimization,effect evaluation index system and index weighting system,are constructed by theoretical analysis and expert interviews.Later than this,the Ex Spect software is selected to simulate the feasibility of purchasing process optimization planning and the FAHP method is selected to evaluate the actual implementation effects of the purchasing process optimization.Last but not the least,in this thesis,taking A Enterprise as an example,the study of the NPD-oriented purchasing process optimization and the effect evaluation system proposed by this thesis is applied to reaearch the purchasing process optimization of the LED car lamp development project in A Enterprise.Through the related theory,case study and empirical analysis,the thesis suggests that in the situation of new product development,the purchasing process should be designed and analysied according to the responsibilities and tasks of purchasing in the different stages of new product development.In addition,based on the actual needs of different enterprises,the purchasing process with problems is improved reasonably to support the new products development effectively and efficiently.Meanwhile,a scientific and comprehensive evaluation of the purchasing process optimization effectiveness is carried out according to the evaluation requirements of different stages of the optimization process.To sum up,this thesis not only enriches the theoretical system of purchasing process optimization in the context of new product development,but also provides practical and effective guidance for the optimization of purchasing process in the new energy vehicle development projects.
