In order to find the optimal intervention program for municipal infrastructure networks (e.g. road, gas or water distribution), a combined methodology is necessary to take into consideration the costs of interventions in terms of owner costs, but also potential losses of service before, during and after the execution of the interventions, and the costs due to the loss of service when interventions are being executed. It is also necessary to take into consideration: 1) intervention cost reductions are possible when interventions are executed on multiple networks simultaneously and 2) interventions on one network can increase the failure probability of another network. This paper presents a methodology to determine optimal intervention programs for multiple infrastructure networks simultaneously using a single mathematical representation, taking into consideration these issues. The service loss is modeled using a new generic model applicable to all networks. The methodology is discussed, and recommendations for future work are provided.
