    Mathematical Model of Containers Placement in Rail Terminal Operations Problem
    (2019) Grebennik, I.; Dupas, R.; Urniaieva, I.; Kalaida, N.; Ivanov, V.
    In the paper the increasing of efficiency for rail terminal operations is analyzed. The problem of optimization the placement of containers on railway platforms and in the storage area at railway transshipment yard is formulated. A combinatorial optimization model of the problem is constructed, its properties are discussed, an example is considered.

    Three-dimensional one-to-one pickup and delivery routing problem with loading constraints
    (2016) Grebennik, I.; Lytvynenko, O.; Baranov, O.; Dupas, R.
    We propose mathematical model and solving strategy for PDP with 3D loading constraints in terms of combinatorial configuration instead of traditional approach that uses boolean variables. We solve traditional one-to-one Pickup and Delivery Problem in combination with problem of packing delivered items into vehicles by means of proposed combinatorial generation algorithm.

    Train arrangement in scheduling for rail-rail transshipment yard
    (UNWE, 2017) Grebennik, I.; Dupas, R.; Lytvynenko, O.; Urniaieva, I.
    Article considers problem of scheduling freight trains in rail-rail transshipment yards. Besides scheduling the service slots of trains, article additionally solves the problem of train arrangement, i.e. assigning each train to a railway track. Mathematical model and solving method for described problem are given. The key feature of given mathematical model is that is uses combinatorial objects (tuples of permutations) instead of traditional Boolean variables. Solution method is based on generation of combinatorial sets as well, which is quite unusual approach comparing with existing solution methods for described problem.
