Spped as a vessel traffic optimization criterion

Problems of vessel traffic organization in approach channels are solved by Vessel Traffic Management Services (VTMS). One essential task for VTMS is to ensure a required level of traffic safety. As often vessel traffic is intensive, attempts are made to optimize it. This author aims to find a relevant solution based on a mathematical model, in which vessel speeds at particular fairway sections are varied. The model belongs to the class of mixed integer linear programming. The branch-and-bound method has been adapted to the proposed solution of the problem. The results are shown in tables, while certain aspects of solutions are illustrated graphically.
