RISK-BASED EXPENDITURE ALLOCATION FOR INFRASTRUCTURE IMPROVEMENT

Traditional methods of modeling and simulating lifecycle for infrastructure management, including bridge management systems, commonly do not account for risk associated with potential failure scenarios. These methods need to be reexamined to take advantage of risk technologies. In this paper, methods for performing reliability computations and managing information that are suitable for risk-informed expenditure allocation in lifecycle management are proposed. The methods include structural reliability assessment methods and the analytic hierarchy method for multicriteria ranking. The paper also presents the advantages of using web-based computing through an example of system reliability assessment software that can be used in an interactive web environment.
