A product energy-saving scheduling optimization method for flexible manufacturing systems

Abstract

The invention discloses a flexible manufacturing system-oriented product energy-saving scheduling optimization method, which belongs to the technical field of production scheduling. The implementation method of the present invention is as follows: obtain the product structure, processing and assembly resources of the workshop, construct a product structure set and a production resource set; construct a process set, process time set, and energy consumption set; As the actual completion process, the process forms the assembly constraints, and integrates the assembly constraints into the flexible production scheduling model to construct the flexible manufacturing scheduling model; the flexible manufacturing scheduling model is optimized through the improved multi-objective particle swarm-genetic algorithm, which can ensure the optimization speed, It can also improve the convergence of the algorithm and obtain a flexible manufacturing system scheduling scheme with a better objective function. The scheduling scheme can integrate the production process and assembly process of the product into consideration, and is more suitable for the existing production and assembly conditions, thereby reducing the production time of the product , to reduce energy consumption during product production.

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 ...
