Review on transportation scheduling problem

Transportation by railroads and airlines contains a rich set of optimization problems with substantial potential savings in transportation costs. In the past few decades, unfortunately, optimization models were not widely used in transportation industries, because of (i) the large size and tremendous complexity of these problems (ii) the lack of suitable algorithmic approaches for solving them, and (iii) insufficient computing power available. The paper gives an insight to several real-life transportation scheduling problems that are of great importance for railroads and airlines.
