Research on flexible scheduling methods with multi-objective in the job shop based on combinatorial rule

Based on the two-level combinatorial rule,the method of flexible scheduling with multi-ob-jective in the job shop is presented to improve the real-time performance of scheduling by taking advantage of less calculation and rapid realization of rule scheduling.In order to get the optimal seheduling scheme coinciding with real-time conditions,the weights of selective performance indexes optimized are determined by combining practical requirements of the production system with real-time conditions and applying the maximum deviation to analyze the rule scheduling results.Finally,a simulation example is given to verify the validity of this scheduling method.
