题目：Sailing speed optimization for container ships in a liner shipping network
作者：Shuaian Wang, Qiang Meng

批注：这篇文章只做了粗读，主要关注的是做出来的航速和燃油消耗量的结果，这个结果以后自己也可以直接拿到论文里面使用。

According to the literature review, we assume that the daily bunker consumption Q (tons/day) and sailing speed v (knot) has the power relationship:

where a and b are coefficients to be calibrated from real data.We can transform it into an equivalent form:

Therefore, we can consider ln v as the independent variable and ln Q as the response variable, and use the conventional linear regression method to calibrate parameters ln a and b.

批注：以后要用到航速和燃油消耗量的关系可以直接引用他这里的结果。船舶日耗油量(吨/天)=0.01航速(节)的立方，船舶每海里耗油量(吨/海里)=船舶日耗油量(吨/天)/(24 航速(节))= 航速航速(节)的立方 0.001 航速的平方。
