Flood control scheduling method based on fusion multi-strategy improved grey wolf algorithm

The invention discloses a flood control scheduling method based on a multi-strategy fusion improved grey wolf algorithm. The flood control scheduling method comprises the following steps: acquiring sample data of flood and a reservoir; establishing a flood control dispatching model; a grey wolf algorithm is improved, improved Tent chaotic mapping is utilized to initialize a population, Levy migration and tangent migration are mixed, an elite retention strategy is added to determine the position of an alpha wolf, parabolic spiral approaching is utilized to determine the position of a beta wolf, and the position of a gamma wolf is determined according to the positions of the alpha wolf and the beta wolf. Determining the position of an omega wolf by combining the Cauchy variation and the dynamic weight coefficient, and adding a cosine convergence factor to obtain a multi-strategy-fused improved grey wolf algorithm; and performing flood control scheduling simulation on the flood by adopting the multi-strategy-fus
