Optimizing Ship Speed to Minimize Total Fuel Consumption with Multiple Time Windows

Abstract EN

We study the ship speed optimization problem with the objective of minimizing the total fuel consumption.

We consider multiple time windows for each port call as constraints and formulate the problem as a nonlinear mixed integer program.

We derive intrinsic properties of the problem and develop an exact algorithm based on the properties.

Computational experiments show that the suggested algorithm is very efficient in finding an optimal solution.
