Creating an optimal portfolio for projects is one of the main issues discussed in the projects portfolio management. Selecting the right portfolio projects guarantees the excellent performance of the project portfolio management and the organization mission achievement becomes more probable if this combination is chosen more suitably. A
bi-objective model is proposed in this research based on the strategic goals, cost and the time for the optimal selection of the projects portfolio which, by being solved, leads to obtaining a suitable combination of the projects for achieving the maximum value of strategic goals with the minimum cost in the determined time horizon. Different sections of the Iran Railways Company should select and manage their investment for achieving the strategic goals in the 2021 horizon and wisely choose and execute their projects, one of the most important sections of the Iran Railways Company is the signaling and telecommunication section, in where 120 projects are defined. This model was implemented on 120 projects of the signaling and telecommunication section of the Iran Railways Company and after solving, 81 projects were chosen and scheduled in a way that the Iran railways Company will have the minimum distance with its strategic goals with the minimum cost until the end of 2021.
