The main aim of this study, introduce a model todetermine the optimal values of the index value to minimize thetotal expected cost index and also the best decision making inselecting the industry and the region for investment by investors.For this purpose, the technique of linear programming to determinethe optimal values of the index value is used. Finally, FuzzyTOPSIS technique to prioritize alternatives to determine theoptimal industry and region to investment is used. Furthermore, acase study that includes two regions and two industries ispresented to show applicability and performance of the proposedmodel. The results show that fourth alternative (region2 andindustry 2) is the best decision to investment. تفاصيل المقالة
