Multi-criteria model for annual rehabilitation planning of water supply networks: sensitivity analysis and impacts of the quantity of data
نویسندگان
چکیده
Annual rehabilitation programme of water supply networks requires taking several points of view into consideration. Within the European project CARE-W (Computer Aided Rehabilitation of Water networks) a multicriteria tool was defined: Care-W_ARP, dedicated to the selection of the most efficient project for annual rehabilitation programmes. This selection is supported by the use of an outranking method: ELECTRE Tri. This model is briefly presented. A sensitivity analysis is proposed in order to assess the impact of data availability on final results. Tests and simulations are carried out with data from Reggio Emilia (I). Four decision contexts have been defined by combining two sets of history (8 or 4 years) with two sets of variables (material, diameter, traffic). Finally, a discussion and an interpretation of programmes obtained regarding the four contexts are presented.

In this paper, a bi-objective multi-product single-vendor single-buyer supply chain problem is studied under green vendor-managed inventory (VMI) policy based on the economic production quantity (EPQ) model. To bring the model closer to real-world supply chain, four constraints of model including backordering cost, number of orders, production budget and warehouse space are considered stochasti...
