Carbon emission optimization method based on target cascading analytical method

Abstract

According to a carbon emission optimization method based on a target cascading analytical method, a production process is divided into a top multiple-workshop scheduling layer, a middle single-workshop scheduling layer and bottom manufacturing unit planning layers, wherein an optimal production scheme of a manufacturing unit of each manufacturing unit planning layer is respectively designed, the carbon emission of each producing activity is calculated, multiple layers of coordination and optimization of carbon emission based on the target cascading analytical method are carried out, the production scheme of each manufacturing unit planning layer is optimized and designed again, and one more cycle time is optimized. The carbon emission optimization method based on the target cascading analytical method tightly combines an optimization process and an energy collecting and monitoring device, improves energy comprehensive utilization efficiency of large-scale distributed manufacturing enterprises, and lowers energy use cost. By mean of the carbon emission optimization method based on the target cascading analytical method, the requirement for individual energy conservation and emission reduction of different types of workshops of the distributed manufacturing enterprises can be met, the carbon emission optimization method can be provided in the manufacturing process of the distributed products, and positive effects of promoting the energy-saving technology to be rapidly popularized and applied in the manufacturing enterprises are achieved.

Description

technical field [0001] The invention relates to the technical field of production energy saving, in particular to a carbon emission optimization method based on a target cascade analysis method. Background technique [0002] Due to the increasingly complex production process of the manufacturing industry, the gradual increase of product types, and the increasingly cumbersome production process, and the products are basically completed by multiple distributed heterogeneous workshops, each workshop has a different production line (or manufacturing unit) or production process To process different parts of the product. The entire life process of a product, including all stages of manufacturing, use, and disposal, must be in harmony with the environment. As an indispensable part of production, processing and manufacturing equipment should play a role in reducing carbon emissions and energy consumption. important role. Large-scale distributed manufacturing enterprises need to co...

AI Technical Summary

Problems solved by technology

[0003] The distributed product manufacturing process is different from the traditional product manufacturing process. The following problems need to be solved in the actual application of traditional carbon emission reduction methods: ①Distributed manufacturing multi-workshops are mostly heterogeneous, and the emission indicators of each workshop are different. , the variety of products produced is also different, and different workshops require different scheduling models, which cannot be optimized together; ②The carbon emission process of the distributed product manufacturing process is generally very complicated, and the real environment has to be greatly simplified when modeling. The optimal solution time increases exponentially as the scale of the problem increases, which is only suitable for solving small-scale problems; ③For large-scale distributed production enterprises, there are generally carbon emission indicators, but each production enterprise is independently operated. Most of these indicators rely on manual distribution to each workshop or manufacturing unit
