With the increasingly fierce market competition and rapid changes in the external business environment, for the sake of survival and development, new product development (NPD) is as the investment for the enterprises’future and becomes the source of competitive advantage and power gradually. It is worth noting that the way of project becomes the main way of NPD implementation. As long as the number of NPD projects becomes more and more, how to screen and optimize projects portfolio in order to ensure that the projects to be implemented are feasible and support srtrategic objectives effectively with limited resources has been a very important issue to enterprise managers. At present, the problem of how to select NPD project has attracted scholars’attention and has achieved some research results. However, the existed research hasn’t formed theoretical system and the relative methods that has been found is few. Therefore, refining the problems of screening and portfolio optimization of NPD projects and giving the relative methods have theoretical significance and realistic meaning.Based on the existence of research related to this article, this article researches the problem of NPD projects selection systematically according to overall structure "build theoretical framework of NPD project selection-Key factors identifying and analyzing-screening of NPD projects-portfolio optimization of NPD projects". The purpose and significance of this research lies in two aspects:in the theory and method research aspect, this article uses multiple-disciplinary research methods, expands areas of application of relevant disciplines, enriches research content of NPD management and NPD project selection, and give some contribution for further research; in applied research aspect, the theoretical framework of NPD projects selection and the methods for NPD projects screening and portfolio optimization provide guidance to enterprises for relevant work.The mail work of this article is as follows:(1) The overall framework of NPD projects selection is given and the key factors that influence NPD projects selection are identified and analyzed firstly. The framework includes process of two parts of NPD project selection including NPD projects screening and portfolio optimization, supported theory and methodology system of NPD projects selectio and formal description of problems of NPD projects screening and portfolio optimization. Aim to NPD projects screening and portfolio optimization key factors of are identified respectively.(2) The method of NPD projects screening is given. Based on the key factors analysis that influence NPD projects screening three dimensions of screening are determined, screening index system is constructed and the criteria of screening is certaintfied. Considering the given evaluation information by experts is linguistical, a screening method based on the2-tuple information processing is given.(3) The method for NPD projects portfolio optimaztion is given. Based on the key factors analysis that influence NPD projects portfolio optimaztion two dimensions of portfolio optimaztion are determined and dicision matrix model of portfolio optimaztion and optimazation index system is constructed. Considering the given evaluation information by experts is linguistical, a fuzzy multi-attribute comprehensive evaluation method for expected reture of NPD project and a evaluation method of risk of NPD project base on fuzzy reasoning are given. Based on results of optimization evaluation, a multi-objective decision model is constructed in which variable is0or1. NPD projects portfolio optimization result can be obtained through solving the model.(4) The case of BG Corporation’s NPD projects’screening and optimization is presented. The background of BG and BG’s NPD are described and the poposed theories and methods in this article are applied to BG corporte’s relative work.The methods for NPD project optimization evaluation are given. The dimensions of NPD project optimization evaluation are proposed and the index of evaluation is constructed. After that, aiming at new product expected return a method based on fuzzy comprehensive evaluation is given; aiming at new product risk a method based on fuzzy reasoning is given. The two kinds of results can be described directly through a matrix model and the description gives the basis to NPD project portfolio selection. A numerical example is given to illustrate the application of these methods.The proposed theory and method in this article provide reference and guidance for theotical research and practical for solving practical problems of enterprises’NPD projects selection.
