摘要

Infrastructure is prone to risks of different nature in all phases of its life cycle. These risks have a multifaceted effect on the operation, safety, and performance levels of the infrastructure systems, thus affecting the social and economical status of communities. Therefore, proper risk management of infrastructure in its whole life cycle is imperative towards attainment of the desired infrastructure systems' efficiency levels. This paper presents the advancement of a new risk based decision making methodology that indicates the preferable risk-response strategy between: a) acceptance, b) mitigation, c) transfer and d) avoidance; the selection of the strategy is based on the quantified risks that are included in the analysis. The methodology is presented through an explanatory example concerning the repair/maintenance costs of infrastructure facilities. The example demonstrates the methodology's capacity to facilitate risk based decision making for infrastructure systems.
