In an electric utility, it would be necessary to predict and make a future view of electric energy strategy for long-term generation expansion planning. The planning problem of energy strategy is formulated as a decision problem of electric generation system in a future horizon year. This problem is considered to be a sort of multiobjective planning problems under several constraints of which some parameters are uncertain. The objectives and some constraints are not necessary to be fulfilled perfectly, but some tolerances by a decision-maker's will may be allowed to them. That is, they can be regarded as fuzzy objectives and fuzzy constraints. This paper presents the fuzzy decision analysis of strategic generation system planning problems using a fuzzy linear programming technique and some numerical examples for a future power system are demonstrated.
