Using engineering economy techniques with group TOPSIS method for best project selection

Selecting projects are an important problem, yet often difficult task. It is complicated because there is usually more than one dimension for measuring the impact of each project and especially when there is more than one decision maker. This paper considers a real application of project selection for Telecommunication projects with using the opinion of experts by one of the group decision making model, it is called TOPSIS method. There are five kinds of criteria that they are include qualitative, quantitative, negative and positive criteria have been considered and also two of them are Net Present Value and Benefit-Cost Analysis that they are engineering economic techniques for selecting the best one amongst five projects and ranking them. We have also used from six expert’s opinion in Cable Network. Finally the introduced method is used in a case study (Telecommunication sector) and extracted results from it are analyzed from different points of view.[12
