Policy impact evaluation and optimization method for forbidding plastic drinking water bottles

Abstract

The invention discloses a quantitative analysis method for policy impact evaluation and optimization based on an entropy weight method and multi-objective programming. The method comprises the steps that main influence indexes of a plastic drinking water bottle forbidding policy are determined according to various influences generated in the plastic drinking water bottle production process and theinfluence of the plastic drinking water bottle forbidding policy on life of people, and the weight of each influence index is calculated through an entropy weight method; constructing a multi-objective optimization model on the basis of three objectives that the influence on the environment is minimum, the influence on the life of people is minimum and the cost of purchasing bottled water by people is minimum after the policy of forbidding execution of the plastic drinking water bottle is executed; and searching an optimal solution of the multi-objective optimization model through a genetic algorithm, and quantitatively analyzing an optimization method of each influence index. The method quantifies the execution effect of the policy of prohibiting the plastic drinking water bottle, is beneficial for a decision maker to reasonably improve the policy of prohibiting the plastic drinking water bottle, and has relatively high application value.

Description

technical field [0001] The invention relates to the evaluation and optimization of the impact of environmental protection policies, and specifically aims at the policy of banning plastic drinking water bottles, and establishes a quantitative analysis method for the evaluation and optimization of the policy impact based on the entropy weight method and multi-objective programming. Background technique [0002] The random discarding of plastic water bottles has brought great risks to the earth on which people depend for survival. According to relevant statistics, the global sales of plastic drinking water bottles reached 480 billion in 2016, but less than 100 million plastic drinking water bottles were recycled. Half of them, only 7% are reused, and most of them are mixed into garbage and landfilled or flowed into the ocean. It is estimated that by 2021, the global consumption of plastic water bottles will reach 500 billion per year, and the vast majority of plastic water bottl...
