Yongkui Shi, Jian-sheng Shao · 2010
The forecast of logistics cost is the prerequisite and foundation for logistics cost management in coal enterprises. This paper has analyzed the logistics cost in coal enterprises and its influencing factors, using PSO-BP and BP network respectively to forecast the logistics cost in coal enterprises. As a result, it comes to a conclusion that the convergence speed and the predicted accuracy of PSO-BP network are obviously better than that of BP network.
