Among the various civil public transportation infrastructure systems, subway systems represent a great challenge. The Société de Transport de Montréal (STM) estimated an amount of 5.1 billion Canadian Dollars for its subway system infrastructure's maintenance for the next ten years. Assessing the existing performance and predicting the future performance of subway system infrastructure for the remaining service life is vital for the effective maintenance and repair (M&R) management. Most transit authorities, including STM, lack structural performance assessment and performance models for the subway system. Therefore, the objective of this research is to develop a subway system structural performance modeling entitled "SUbway PERformance" (SUPER) model. The SUPER model identifies the structural systems hierarchy, assesses the performance of components using physical and functional conditions, and develops components' performance curves. The SUPER model is developed using the Analytical Hierarchy Process and the Multi-Attribute Utility Theory. In order to develop the performance curves, the model uses reliability-based cumulative Weibull function and the parallel/series system modeling. Data, which are used to prove the SUPER model's concept, are collected from STM inspection reports and questionnaires. The developed model is applied to STM case study. The implementation showed that component performance of the case study drops from 1.0 to 0.9 along 30 years. This research is relevant to industry practitioners (management, engineers, and field inspectors) and researchers since it develops a performance assessment and a performance curve model of subway systems' components.
