Inspection and M&R Decisions for Infrastructure

by Samer Madanat, Purdue Univ, West Lafayette, United States,



Document Type: Proceeding Paper

Part of: Infrastructure: Planning and Management

Abstract:

This paper reviews different possible mathematical formulations for a joint inspection and M&R decision-making model, having various levels of restriction and computational complexity. An empirical comparison of the different formulations is presented. It is concluded that optimizing inspection decisions jointly with M&R decision can lead to lower life-cycle costs than what is achieved by simple M&R decision models with a predetermined inspection frequency of once per period.
