Abstract

The invention relates to an adaptive genetic algorithm-based mixed flow shop sustainable scheduling control method. The method comprises the following steps of: 1) obtaining shop processing information which comprises a workpiece number, processing procedures, a machine number on each procedure, processing time of the workpieces on the machines, unit residence energy consumption of the workpieces,unit waiting energy consumption of the machines and last procedure batch processing information; 2) establishing a mixed flow shop scheduling model, taking minimized energy consumption as a target, for last procedure batch processing; and 3) solving the scheduling model by adoption of an adaptive genetic algorithm so as to obtain an optimized scheduling scheme. In the adaptive genetic algorithm,encoding and genetic recombination are carried out in a layering manner on the basis of mixed flow shop processing characteristics, and populations are updated by adoption of adaptive crossing and mutation probabilities. Compared with the prior art, the method has the advantages of being obvious in energy saving effect and high in solving efficiency.

Description

technical field [0001] The invention relates to the technical field of production energy-saving control in the manufacturing industry, in particular to a sustainable scheduling control method for a mixed flow shop based on an adaptive genetic algorithm. Background technique [0002] Although there have been many research results on the Hybrid Flowshop Scheduling (HFS) problem, most of the research has simplified the actual problem and lacked the consideration of the complex scheduling situation in the actual production environment. It is reflected in that, on the one hand, current research results often aim at optimizing production performance, for example, minimizing the maximum completion time, total processing time, and total delay time. However, with the emergence of environmental issues and rising energy costs, more and more attention has been paid to the sustainable development of manufacturing, especially how to optimize energy consumption in the production process is...
