Sustainable determination system for remanufacturing system based on energy, environment and economy

Abstract

The invention belongs to the technical field of control and regulation, and discloses a sustainable determination system for a remanufacturing system based on energy, environment and economy, and thesystem analyzes the energy consumption through an energy consumption analysis module, and builds an energy consumption prediction model. The method comprises the steps of analyzing the processing costand the material purchasing cost of the total part remanufacturing cost through a cost analysis module, and establishing a part remanufacturing cost prediction model; calculating the carbon emissionof each workshop in a certain time period through a carbon emission calculation module according to an emission factor method; allocating the total carbon emission to each remanufactured part producedin the time period, and establishing a carbon emission prediction model and an environmental benefit prediction model; and evaluating the remanufacturing system through a comprehensive benefit evaluation module, and deciding an optimal scheme. According to the method, on the basis of evaluating the remanufacturability, the index for measuring the remanufacturing sustainability is established, theremanufacturing sustainability is evaluated, and the remanufacturing advantages are maximized.

Description

technical field [0001] The invention belongs to the technical field of control and adjustment, in particular to a sustainability measurement system for a remanufacturing system based on energy, environment and economy. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Climate change and its related costs brought about by the use of fossil fuels are worrying, and governments and companies around the world are actively looking for countermeasures. Sustainable development has become a global consensus. With technological progress and policy implementation, energy efficiency can be improved, which leads to lower energy consumption and environmental impact while obtaining higher economic benefits. Energy savings have led to a reduction in greenhouse gas emissions of more than 4 billion tons of CO2 equivalent between 2000-2016, and without these energy savings, emissions would have increased by 12.5% ​​in 20...

AI Technical Summary

Problems solved by technology

There is no unified evaluation standard, and the current methods are mixed; the index analysis is not clear enough, and qualitative analysis methods are mostly used, which has a great impact on the accuracy of the evaluation results; the evaluation process is mostly human-involved and subjective

[0013] (2) Usually, only a certain link in the remanufacturing process is studied, and energy conservation and environmental protection are aimed at this link, and the entire remanufacturing process is not extended; usually only the influence of a single index is considered or only a single index is studied Optimization, the comprehensive optimal solution cannot be determined; only a single goal is considered, and the remanufacturing system can only be optimized for this goal, which may lead to very poor impact on other aspects

For example, if only the cost of remanufacturing is considered, the cost of remanufacturing may indeed be minimized in the end, but it may also lead to problems of excessive energy consumption and more serious environmental pollution.

[0014] (3) Usually only the remanufacturability of waste products is evaluated, the advantages of the remanufacturing system are compared with the manufacturing system, and the advantages of the remanufacturing system are pointed out relative to the manufacturing system, and the advantages of different remanufacturing systems are not studied. Inferior, it is impossible to obtain a comprehensive and optimal remanufacturing solution

[0016] (1) The method system of the existing technology for the analysis and evaluation of the remanufacturability of waste products is still immature;

[0017] (2) The existing technology does not extend to the entire remanufacturing process; usually only the influence of a single index is considered or optimized for a single index, and the comprehensive optimal solution cannot be determined

[0018] (3) Usually only the remanufacturability of waste products is evaluated, and the advantages and disadvantages of different remanufacturing systems are not studied, so it is impossible to obtain a comprehensive and optimal remanufacturing plan;

[0019] (4) The existing technology has not established a unified quantitative analysis model and a complete evaluation system and system, so there is still a large blindness in remanufacturing, and it is difficult to find the most suitable remanufacturing process route
