Prediction of Municipal Solid Waste Production in Changchun City Based on Gray Model GM(1,5)

Abstract:

Using gray relational analysis, the relational degree between the production and impact factors of municipal solid waste (MSW) is calculated. Based on gray model GM(1,5) and gray model GM(1,1), the prediction models of MSW production were set up, on which base, MSW production from 2010 to 2020 in Changchun city is predicted. The result shows the waste production prediction models on gray theory have minimal residuals, higher precision and a relatively high relational degree, and by 2020, MSW production in Changchun City will reach 228.67×104 t by estimation.
