The most significant challenge facing municipalities today is a shortage of funds required to upgrade or expand aging infrastructure. A chronic lack of funding impairs a municipality's ability to maintain desired infrastructure levels of service. Over the last decade, municipalities in Canada have faced the pressures of increased complexities in infrastructure asset management decision making, which to some extent is attributed to cost escalation, increasing demand, and interdependencies between infrastructure networks. This paper presents a framework to develop an asset levels of service (ALOS)-based decision support system for municipal infrastructure funding investments. This paper focuses primarily on the allocation of funds in the maintenance, rehabilitation, and repair (MR&R) of municipal networks based on ALOS, future demand, and network interdependencies.
