However, because of the failure rate of these projects, it could not be expected firm’ success due to only one new product development project. Therefore, it should be selected a portfolio of new product development projects. In this research by literature review and interview with experts 20 criteria for evaluating new product development projects in disposable medical product extracted. Then by using analytic network process (ANP) based on DEMATEL method degrees of influences given and received among these criteria and also weights for each criteria based on correlation between them calculated. Finally, by evaluating NPD projects with VIKOR method, best portfolio selected. The proposed model is capable of considering complex interrelationship and interdependency between criteria and dimensions for more accurate project selection as well as providing appreciate solutions to improve selected portfolio performance by measuring these interrelationships between criteria and their effective degree and affected degree.

Portfolio selection problem is an important field of capital assignment and budgeting in managerial finance and had proposed patterns for optimal selection of portfolio from the past. For this purpose we suggest a fuzzy ranking method with mathematical approach. This research is a survey in Tehran stock exchange. Statistical population inclusive 50 superior companies of Tehran stock exchange in 1387. By survey of financial data of these companies, 20 companies have selected and weekly returns in 1387 have been calculated for them. In first stage, 20,000 random portfolios have been generated by a computer program. Each of these portfolios is composed of 20 companies that quantity of investment in each of them are between 0% and 100% and selected randomly. The uncertainty on the returns of each portfolio is approximated by means of a trapezoidal fuzzy number. A rank index that accounts for both expected return and risk is defined, allowing the decision-maker to compare different portfolios and select best portfolio. Conclusions showed that, according to risk aversion of investor, several optimal portfolios can be selected. In this article we suggested 3 optimal portfolios.
