Multicriteria analysis with a large-scale energy supply L.P. model

This paper presents a methodology and an application for performing multicriteria analysis with a large-scale linear programming energy supply model. It is applicable when the dimension and the software of the model do not permit the use of a complicated multiobjective algorithm searching for a best compromise solution. The method is based on a version of the constraint method for generating efficient solutions. A methodology is proposed for exploring progressively the set of efficient solutions and structuring the information obtained. This procedure provides abundant and usable information to the decision maker and helps him to choose among alternative decision paths and, thus, to orient the reduction of the efficient domain to explor. The analysis is illustrated with results obtained from the EFOM-GRESOM energy supply model.
