Abstract:

To address the issue of predicting the quantity of waste electronic products with small data, a prediction method based on the Susceptible-Infective-Removed (SIR) infectious disease model is proposed. Taking into account the small data characteristics of the time series of new generation electronic products, a Sales-Transfer-Adjustment (STa) optimization model with the minimum time-weighted average error is constructed. To estimate the parameters of the STa model, the Particle Swarm Optimization (PSO) algorithm is introduced. Furthermore, the reasonable lag time of the transfer quantity is determined via the concept of differential compensation prediction, which enhances the prediction accuracy of the new generation electronic product quantity. Based on the availability of electronic product data, the Estimation Model of Waste Quantity of Electronic Products (EWE) is used to predict the waste quantity of new generation electronic products. Through empirical analysis of 4 data sets of rural TV sets and mobile phones in China, it is found that the performance of the STa·PSO-EWE model is generally superior to that of other benchmark comparison models.
