Evaluate projects by using multiple criteria decision making techniques

In the economic analysis of projects available to the firm, the objective is to decide, from the economic data available, whether or not a given project is acceptable to the firm. There are four common methods of comparing alternative investments: net present value, rate of return, benefit-cost analysis and pay back period. In this article by utilizing improved analytical hierarchy process by rough set theory, firstly we try to calculate weight of each method. Then by implementing TOPSIS algorithm assessment of projects has been done. Obtained results have been tested in a numerical example.
