ABSTRACT
In this work, we consider a
specific problem of optimal planning of maritime transportation of multiproduct
cargo by ships of one (so-called “corporate strategy”) or several
(so-called “partially corporate
strategy”) companies: the core
of the problem consists of the existence of the network of intermediate
seaports (i.e., transitional
seaports), where for every ship arrived the cargo handling is done, and which
are situated between the starting and the finishing seaports. In this work,
there are mathematical models built from scratch in the form of multi-criterion optimization
problem; according to the properties of the criteria and structure of the
feasible solution set; are formulated different optimality conditions; are
analysed different approaches for finding effective solutions (i.e., Pareto optimal
solutions) and for check of the given solutions’ effectiveness. In addition, in this work, there is considered and
analysed well-known method of contraction of the Pareto boundary (goal
attainment method of Gembicki), then, it is used for reducing the built models to a one-criterion
problem of linear programming.
