Research on Job Shop Scheduling Problem Based on Genetic Algorithm

Abstract In the current environment of modern production, the demand for products is more and more strict, and the enterprise's management system and technical level are more and more strict because of the shortening of production cycle。 Job shop scheduling is one of the main means of production and management。 Job shop scheduling optimization greatly improves the production efficiency of the workshop, and reduce the resources for loss and make the enterprise more competitive。 The development path of the scheduling problem of several optimization method makes some introduction, and also explains the genetic algorithm, simulated annealing method, Lagrange relaxation method and artificial neural network (ANN) method, and the characteristics of these methods are described。

In this paper, genetic algorithm is used to solve the job shop scheduling problem。 Through the basic idea of genetic algorithm, the basic process and the operator selection, crossover, variation of understanding, and the characteristics of the analysis, to determine the genetic algorithm to solve job shop scheduling problem is reasonable。 In view of the characteristic of job shop scheduling problem, the basic process of genetic algorithm is redesigned, and some algorithms are revised。 On the MATLAB for simulation algorithm, the algorithm is obtained with the differences between the various parameters affect the simulation diagram and the corresponding Gantt chart。 Finally the simulation results are analyzed and came to the conclusion that the genetic algorithm for job shop scheduling optimization problem is feasible and effective。

The paper has tables 6, figures 24, 16 references。
