Multi-target factory aquaculture feeding scheduling optimization method based on enhanced NSGA-II

Abstract

The invention discloses a multi-target factory aquaculture feeding scheduling optimization method based on enhanced NSGA-II. The method comprises the following steps: 1, defining model parameters, and establishing a scheduling model; s2, adopting double integer coding, and initializing to obtain original different code pairs; s3, if Rand (0, 1) is less than or equal to Pc, performing interlace operation on the coding pair, otherwise, skipping the operation; s4, if Rand (0, 1) is smaller than or equal to Pm, mutation operation is carried out; otherwise, skipping the step; s5, searching a better scheme according to a greedy neighborhood search strategy; s6, improving the survival rate of members according to an elite selection strategy; and S7, decoding the coding pairs by adopting a scheduling strategy, and determining the feeding trolleys distributed to each feeding pond and each supply station. According to the multi-target factory aquaculture feeding scheduling optimization method based on the enhanced NSGA-II, the problems that the feeding amount cannot be accurately controlled during fixed-time feeding, feed waste, water pollution, biological diseases and the like are easily caused are solved.
