Abstract:
The current paper briefly presents the infrastructure asset management (IAM) methodology developed in the framework of the AWARE-P project for the comparison of alternative rehabilitation solutions and applies it to a Portuguese water supply system taking into consideration different criteria. These criteria incorporate three assessment dimensions – performance, cost and risk – expressed by several assessment measures (e.g., investment cost, risks of pipe leakage, risk of pipe burst and infrastructure index value). Criteria are aggregated by a Multiple Criteria Decision-Aid (MCDA) technique – the ELECTRE III method. Alternative rehabilitation solutions were established and assessed using this approach. Results are presented and discussed.
