Uncertainty analysis method based on environmental impact assessment of Monte Carlo beer equipment

Abstract

The invention provides an uncertainty analysis method based on the environmental impact assessment of Monte Carlo beer equipment, which comprises the following steps: 1) collecting beer equipment resources and energy consumption list in the life cycle process; 2) determining the environmental impact index in the life cycle process of the beer equipment; 3) calculating that total environmental impact load of the beer equipment; 4) performing environmental impact assessment of beer equipment; 5) carrying out uncertainty analysis on the environmental impact index of the beer equipment determinedin the step 4; 6) determining an input variable; 7) determining a variation range / probability distribution of the input variable; 8) performing Monte Carlo random sampling on the determined probability distribution of the input variables; 9) analyzing the output results in R language. The analysis method of the invention can more accurately reflect the distribution of the median value of the inputprobability distribution, increase the accuracy of the environmental impact, provide more reliable and comprehensive decision support for the environmental protection department, and has certain positive significance for the environmental treatment and protection.

Description

technical field [0001] The invention relates to the field of environmental impact assessment of beer equipment, and relates to an uncertainty analysis method based on Monte Carlo environmental impact assessment of beer equipment. Background technique [0002] The development of beer equipment in China is late, and most of the beer production equipment is below the semi-automatic level, which needs to be improved in terms of energy saving and consumption reduction. At present, there are many environmental impact assessments of beer technology. The research found that: beer bottle manufacturing, beer brewing, beer packaging, and raw material acquisition are the stages in the beer life cycle that have a greater impact on the environment. Environmental impact assessment is mostly used in the study of comprehensive evaluation systems, but there are few targeted studies on the environmental impact of beer equipment, and there are few reports on the uncertainty analysis of beer-rel...
