A Flexible Framework for Sustainable Multi-objective Cross-Asset infrastructure Management

The deterioration of infrastructure assets and systems that had been constructed over the past few decades has become a significant challenge. Budget constraints and resource limitations along with the attention to the concept of sustainable development in economical, environmental and social terms have urged the use of more efficient and optimized approaches for managing and operating assets. This has led engineers and decision makers to manage these infrastructures using multi-objective and multi-constraint domain. On the other hand, interactions and interdependencies between different types of assets along with the structure of many agencies coping with multiple assets has revealed the need for further understanding of the concept of “cross-asset management.” This paper reviews the literature and current practice in different steps associated with the cross-asset management process. The research confirms the promising potential for developing a comprehensive framework for sustainable multi-objective cross-asset management.
