Vulcanizing workshop energy consumption optimized dispatching method based on heuristic rule

Abstract

The invention discloses a vulcanizing workshop energy consumption optimized dispatching method based on the heuristic rule. The method includes the steps that firstly, a vulcanizing workshop energy consumption optimized dispatching model is established; secondly, three types of heuristic rule algorithms are proposed for a tardiness cost optimization target in the dispatching model; thirdly, a minimum operation energy consumption heuristic algorithm is proposed for an energy consumption cost optimization target; fourthly, a control machine 'off-on' state algorithm is proposed for machine waiting and halts which affect energy consumption cost; fifthly, based on the lean principle that the number of state conversion times is reduced for energy conservation, a BC algorithm based on workpiece batch machining is proposed; sixthly, based on the principle that the performance of a combinational rule is superior to that of a simple dispatching rule theory, four heuristic algorithms based on the combinational rule are proposed; seventhly, a segmentation experimental method is adopted for designing a simulation experiment case and a simulation experiment is conducted; eighthly, an experiment result is analyzed. According to the method, the dispatching performance is good, the optimizing effect on vulcanizing workshop energy consumption is obvious, and the good energy conservation effect is achieved.

Description

technical field [0001] The invention relates to the fields of automatic control and information technology, in particular to a heuristic rule-based optimal scheduling method for energy consumption in a vulcanization workshop. Background technique [0002] The tire industry is a traditional labor-intensive and technology-intensive high-energy manufacturing industry. Although my country's tire manufacturing industry started late, it has developed rapidly. Since 2004, my country's tire production and export volume have leapt to the first place in the world. However, since 2011, the increase in the price of energy and raw materials has raised the production cost of tire manufacturers, which has put my country's tire industry in a difficult situation. According to the January 2011 report of the Tire Branch of the China Rubber Industry Association, its 45 member companies had a deficit of 37.2%, and their profits fell by 37.6% year-on-year. At the same time, the development tren...
