TASK MODEL: SETTING OF THE ORDER TRAINS DELIVERANCE AT A SORTING RAILWAY STATION
The analysis of the technology of work of a sorting station has revealed major factors influencing staying time of a railway car at accumulation and at a sorting station on the whole. The most important component is the expectation of the "necessary" railway cars. Thus, to reduce it, it is necessary to provide sorting out of trains in such a manner that the deliverance of cars from accumulation would be maximal. Formalized target setting, its place in transportation process is considered in the paper. The given mathematical model allows to solve the task with the help of full scan or search algorithms, such as the algorithm of full scan, the genetic algorithm or the algorithm of ant colony system. For the given formalized target setting it is possible to impose restrictions and take into account "the priorities". The general description of the account at the construction of a model of delivery of perishable cargoes is resulted. The author of the paper offers to sacrifice a simple car in order to deliver perishable cargoes in time. Some aspects of the realization of this task are considered there.
