The Decision of an Eco-Friendly Reservoir Operation Scheme Based on a Variable Set

The river ecosystem has the characteristics of coexistence clarity and ambiguity. starting point eco-friendly reservoir operation is to fully consider ecological water requirements lower reaches reservoir, so it also vagueness. fuzzy theory an excellent tool realize quantification concepts. In this paper, variable set (VS) introduced into decision-making field scheduling scheme optimization. Taking Ertan Hydropower Station as example, optimization carried out. To verify effectiveness evaluation method, paper compares analyzes results method composite matter-element method. show that advantages rigorous theory, a concise model, simple calculation, decision result reasonable reliable. This research can provide new ideas for engineering.
