Multicriteria analysis using a large-scale energy supply LP model

A methodology and an application for performing multicriteria analysis using a large-scale energy supply linear programming model is presented. The methodology is applicable when the dimensions and the software of the model do not permit the use of a complicated multiobjective algorithm searching for a best compromise solution. It 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 easy-to-use information to the decision maker and assists him in choosing among alternative decision paths, thus reducing the efficient domain to be explored. The analysis is illustrated through an example using the E
