This situation leads the administrations to various and innovative searches. Analyzing the current performances of shopping centers and offering appropriate solutions are also a solution to these pursuits. Due to this newly emerged need and, in order to contribute to the development and performance measurement of shopping centers, in this study, a performance index measurement model is developed for shopping malls. In the proposed performance index model, 6 main criteria and 135 sub-criteria were determined. In order to evaluate the performance criteria and the performance of the shopping malls, Analytic Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) methods were preferred. In the application phase of the developed model, the sample of the research was applied to four shopping malls in Istanbul. The analysis of the results, were evaluated comparatively with 2 methods namely SWOT analysis and radar diagram analysis. A far as we know, this study presents, a new and comprehensive model for evaluating the performance of shopping malls first time in the literature. It is hoped that, with the proposed model and proposed solutions, competitive advantage in the retail sector will be achieved and will make a positive contribution to the sector.
