This paper considers the problem of path choice models in transport systems. It is studied within wider models. The main issues discussed are classification utility model, also considering non-random classes as quantum and fuzzy; specification with particular reference to easy-to-apply assignment model; a numerical results comparison small test system allow control each element reproduction. random, quantum, fuzzy different, validity must be tested case by case. With assumed parameters, cover different trends simulating paths overlapping. require application real calibration parameters data.

loads in the structure of a container with floor made sandwich panels under operational modes. To ensure strength container, as well safety cargo transported it, it is proposed to design based on panels. It assumed that each these two metal sheets layer between which an energy-absorbing material placed. Given presence panel, vertical dynamic acting during its transportation will be reduced. substantiate solution, mathematical modeling load by flat wagon was carried out. found accelerations improved are 5.7 % lower than those standard design. The calculation out schemes loads. has been established ensured. A special feature results reduction achieved not strengthening but introducing flexible connections into it. field practical application railroad transport. conditions for use findings form container. research contribute improving containers operating conditions, them, increasing efficiency functioning
