Hybrid optimization of overall scheme of key equipment selection for polar cruise

The multi-objective optimization model with coupling constraints is built. The solution space of the problem is analyzed and a novel hybrid optimization algorithm is introduced. The strategy of the process is described as follows: to introduce the operations crossover and selection into the whale optimization algorithm; to perform dimensions updating for adapting it to coupling constraints; to use greedy selection algorithm to protect dominant individuals. The optimization algorithm is verified with a small polar cruise project.
