ABSTRACT
Prevention is an imperative necessity in all systems, whether natural or artificial ones for their proper functionality and life span’s extension. Infrastructure assets are preeminently multi-components systems with existing dependencies between their components. The extant literature approaches generally the issue of maintenance models in multi-component systems without referring to specific items or deals mainly with systems of machinery and equipment. This research aims to conceptualize the necessary steps for determining the remaining economic status of infrastructure assets by calculating their “Service Value” via a probabilistic dynamic integrated predictive system and implement appropriate maintenance plans that can prohibit false life-cycle cost estimation. The model will be introduced on road bridges as ones of the most critical and difficult to analyze structures in road infrastructure systems. The proposed framework guarantees the financial sustainability of the project, its uninterrupted operation and unplanned traffic delays reduction, thus preventing adverse productivity, mobility and economic impacts.
