Abstract: We have to forecast the production of waste, based on the result of which urban environment design is planned. In addition, this could also reveal the rules and trends governing waste production. This paper analyzes the principles of waste production, by building some models that normally are used to forecast the production of waste, and decides the model of combination forecast. The paper decides on the weight Coefficient, which combines different structure model, to build forecast model for waste production. The results of the cases show that this forecast model has good forecasting precisions and could forecast the production of waste in a city efficiently.
