Abstract: The different operation objectives of a reservoir are neither completely coordinated nor completely opposed. How to quickly obtain multi-objective operation scheme set and make scientific decision is important to realize efficient utilization of reservoir water resources. Taking the maximum power generating capacity and optimal ecological benefits as objective function, a reservoir generation-ecological multi-objective optimization operation model was established, and then an improved Multi-objective Firefly Algorithm (MOFA) for the optimal solution of the model was proposed. Combined with combination weights improved VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method, the operation scheme decision was made, and finally it was applied to the Three Gorges Reservoir operation. The results showed that the improved algorithm can obtain a higher quality non-inferior solution set, and the scheme set optimization method can seek the optimal solution on the basis of maximizing the group benefit and minimizing the individual regret, which can reflect the preference of decision-makers and the objective characteristics of each decision-making index. The research results can provide scientific basis for multi-objective reservoir operation decision.
