Calculation of amount of discarded end-of-life products by using multi-regression analysis

Abstract

For stable equilibrium between disposal of EOL products and supply of recycled materials, production planning is necessary in the recycling plants as well as the usual manufacturing site. As the first stage to make production plan, forecast of amount of discarded EOL products by using multi-regression analysis is investigated in this paper. The results obtained show that the criterion variable, namely amount of EOL products can be calculated by the approximate expression considered population, temperature and so on as predictor variables
