Conventional hybrid forecasting model has been widely used in various forecasting problems, but the sum of weights is limited to 2. An improved hybrid model named as relaxed hybrid model is proposed in this study, where the weights are relaxed to positive real data. The weights are searched by particle swarm optimization algorithm with compress factor technique. The relaxed hybrid model is employed to railway passenger turnover forecasting. The forecasting results show that our proposed model is an effective model for nonlinear time series forecasting.
