Multiobjective approach to weather routing

The paper presents a weather routing solution for sail-assisted ships. Since the route finding optimisation process is a multiobjective one, the emphasis is put on possible application of multiobjective optimisation methods. The paper focuses on two such methods, namely evolutionary algorithms and ranking methods represented by Fuzzy TOPSIS. In addition, a proposed set of optimization criteria is presented. Descriptions of assumed ship and sail models as well as exemplary speed characteristic are also provided. Finally, a proposal of application to a weather routing tool is presented.
