| Abstract: | The paper used the method of mathematical statistics to found themathematical model of the best replacing period of CA-141 transporting trucks. After calculation and analysis of the mathematical model, we found that purchasing fee for new trucks and average cost had directly influence on the best replacing period. If the purchasing fee for a new truck is 60,000$, the best replacing period is 5. 5 year. |
