Abstract:Investment decisions are one of the most important decision-making areas that are difficult and risky. Decision-makers should take multiple alternatives and evaluation criteria into account during project evaluation for the optimum alternative. In this study, a prioritization application for 78 alternative railway line connection projects planned by the Republic of Turkey State Railways (TCDD) to nodes like Organized Industrial Zone (OSB), factory, plant etc. that are carrying high load capacity has been made. Two alternatives were used in this study. In the first alternative, the criteria used in the evaluation of the rail lines were weighted by three different criteria weighting methods such as CRITIC (CRiteria Importance Through Intercriteria Correlation), Standard Deviation (SD) and Mean Weight (MW). Six different priority orders are determined for 78 railway line projects by the application of TOPSIS and VIKOR Multi-Criteria Decision Making (MCDM) methods. After the application of Borda Count Data Fusion Technique, an integrated ranking has been obtained by combining all the rankings derived. In the second alternative, unlike the first alternative, only one criteria weight was considered which is a combination of CRITIC, SD and MW criteria weights. The ranking of two alternatives, which were obtained by Borda Count Data Fusion Technique, were compared by Spearman's Rank Correlation Coefficient (SRCC).
