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.
Modeling of Dynamic Objects and Systems Using Petri Evaluation Networks in an Interactive Environment
(UNWE, SOFIA, BULGARIA, 2017) Ivanov, V.; Grebennik, I. V.
The approach to modeling of dynamic objects and systems by means of Petri evaluation networks is described. As a tool, it is proposed to use the E-NETSIM simulation environment. A formal description of the modeled object is proposed to be performed in terms of discrete-event modeling. An example of a model based on the sequence diagram of a universal modeling language is considered.
