Problems solved by technology

For the multi-objective optimal scheduling problem, the NSGA-II algorithm can use the hierarchical selection method to select better individuals, but after the parent population and the offspring population are merged, there will be a large number of duplicate individuals, which will affect the evolution rate of the population

Abstract

The invention discloses an Internet of Things workshop scheduling method based on an NSGA-II algorithm. The method comprises the following steps: respectively establishing three objective functions based on total processing time, total production cost and longest operation time of single equipment; taking the reciprocal of the three objective functions as a fitness function; establishing a workshop scheduling model according to the objective function and the fitness function; and solving the workshop scheduling model based on an NSGA-II algorithm to obtain an optimal workshop scheduling scheme. According to the Internet of Things workshop scheduling method based on the NSGA-II algorithm, local convergence can be avoided, the population quality can be improved, and a better multi-objective optimal solution can be obtained.
