Maintenance of aging infrastructure is a burden on many organisational budgets,and Life Cycle Cost Analysis (LCCA) is accepted as an effective method to reduce these costs.However,LCCA becomes extremely complex when applied at the individual bridge component level within a large bridge population while considering multiple maintenance strategies,varying deterioration rates and intervention intervals.To address this concern,a decision support model is presented that proposes maintenance actions for future interventions based on a selection of maintenance strategies and organisational budget constraints.
