Product energy-saving scheduling optimization method for flexible manufacturing system

Abstract

The invention discloses a product energy-saving scheduling optimization method for a flexible manufacturing system, which belongs to the technical field of production scheduling. The implementation method comprises the steps: workshop product structures and machining and assembling resources are obtained, and a product structure set and a production resource set are constructed; a process set, a process time set and an energy consumption set are constructed; aiming at the assembly process, the process with the maximum start time of each assembly process is selected as an actual completion process to form an assembly constraint, and the assembly constraint is fused into the flexible production scheduling model to construct a flexible manufacturing scheduling model; and the flexible manufacturing scheduling model is optimized through an improved multi-target particle swarm-genetic algorithm. The optimization speed can be guaranteed, the algorithm convergence can be improved, a flexible manufacturing system scheduling scheme with a better target function is obtained, the scheduling scheme can integrally consider the production process and the assembly process of a product and is moresuitable for existing production and assembly working conditions, and therefore the production time of the product is shortened, and energy consumption in the production process of the product is reduced.

Description

technical field [0001] The invention relates to a flexible manufacturing system-oriented product energy-saving scheduling optimization method, which belongs to the technical field of production scheduling. Background technique [0002] Today, energy and environmental protection have become issues of common concern to all countries in the world. Energy, as the material basis for the normal development of human life, is the material guarantee for rapid economic development and an important factor for the healthy development of the ecological environment. As a big energy producer and consumer, China has experienced rapid growth in energy demand since the reform and opening up, especially since my country entered into the 21st century to carry out in-depth industrialization. According to relevant data from the National Bureau of Statistics, my country's annual total energy consumption has reached 4.3 billion tons of standard coal, and the energy consumption is still increasing ...
