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.

Description

technical field [0001] The application belongs to the technical field of industrial production scheduling, and in particular relates to a method for scheduling workshops of the Internet of Things based on the NSGA-II algorithm. Background technique [0002] With the continuous advancement of my country's industrialization process, the scale of industrial production has gradually expanded, and workshop production scheduling has become more and more complex. Scientific and effective workshop scheduling methods are of great significance to the efficient and reliable production of my country's manufacturing industry, and have attracted more and more attention. [0003] At present, most manufacturing enterprises carry out network transformation of workshops, so that machines can be connected to the network for unified management, but at present, IoT workshops still rely on manual means to allocate and produce orders. This traditional means mainly relies on the experience of manage...
