Solving the Tramp Ship Dispatching Problem Using ACA

2007 Chinese Control Conference, 2006
In the context of the COA signed by Sinopetrol and CSTANKER, this paper try to optimize ship operating plan through the ant colony algorithm (ACA). Based on the practical operation, the ship scheduling optimization model is formulated. And then, we try to solve the model through ACA. Finally, we schedule a real problem through the program.

A Variable Neighborhood Search Heuristic for Tramp Ship Scheduling

2011
This paper considers a classical ship scheduling problem in which the routing and scheduling of a heterogeneous fleet of ships with time windows for pick-ups and deliveries at multiple ports is required. Assuming fixed ship speeds, the problem of maximising profit is addressed.
