Calculation And Optimization For Carbon Dioxide Emissions Of Life-Cycle-Based Factory Transportation

With the development of science and technology, people’s quality of life is also getting higher and higher. Not limited to feed and clothe, but also have a comfortable living environment, blue sky and white clouds, suitable climate. The greenhouse effect is getting worse, it has caused impacts can’t be ignored for people’s lives. Therefore, low carbon life, low carbon travel is increasingly being put on the agenda. The greenhouse effect is mainly caused by the consumption of fossil energy and industrial enterprises is the largest consumer of fossil energy. Industrial enterprises in environmental protection, there is a duty bound responsibility, should start with the various aspects of reducing carbon emissions, reducing the pollution of the environment.The paper takes the industrial enterprise transportation as the breakthrough point, calculates and optimizes carbon dioxide emissions from a life cycle perspective of factory transportation, implements the policy of low-carbon economy, improves and optimizes factory transportation emissions, enabling enterprises to maintain sustainable development.(1) This paper divides the factory transportation according to the life cycle theory into four stages: design stage, construction stage, operation stage and recovery stage, makes life-cycle-based carbon dioxide emissions calculation for several common transportation modes in factory transportation. Qualitatively analyzing factors affecting factory transportation carbon dioxide emissions as well as the relationship between the interaction of various factors, and quantitatively analyzing two main factors: the choice of mode of factory transportation and general layout.(2) This paper introduces the characteristics of several common factory transportation modes and the factors that are considered in the mode of transportation, and emphatically establishes a multi objective quantitative optimization model for the consideration of the carbon emissions and economic costs. The hybrid genetic algorithm which is combination of genetic algorithm and entropy method is used to solve the mode, so that in the selection of the mode of transport carbon emissions of factory transportation and economic costs at the same time to achieve optimal.(3) The significance of the general layout optimization and the basic principles of the general layout are analyzed. According to the theory of life cycle, this paper optimizes the carbon dioxide emissions from the general layout of the design stage, operation stage and expansion stage, takes corresponding optimization method in allusion to the characteristics of each stage and the carbon emissions of factory transportation as the target of the best, so that the whole life cycle of the carbon emissions of factory transportation to achieve optimal.This paper is a preliminary study on the evaluation of the environmental impact assessment of factory transportation based on the whole life cycle. It gives the calculation formula of carbon emission in factory transportation based on life cycle, and provides a method to optimize the transportation of carbon emission from the transportation mode and the general layout angle. It provides a new perspective to reduce the pollution of factory transportation in industrial enterprises, and has a certain research value.
