The article presents the problem of supply chain optimization from the perspective of a multimodal logistics provider and includes a mathematical model of multilevel cost optimization in the form of MILP (Mixed Integer Linear Programming). The costs of production, transport, distribution and environmental protection were adopted as optimization criteria. Timing, volume, capacity and mode of transport were also taken into account. The model was implemented in the LINGO ver.12. The numerical experiments were carried out using sample data to show the possibilities of practical decision support and supply chain optimization.

before the sharp fall in prices on the market in mid-2008. It is also worth noting that the above-mentioned uncertainty of crude oil price on the market volatility increased even more after a significant reduction in crude oil prices in the second half of 2014. As Czyżowski  claims, the market lost its reference point in the moment when the strategy of the Organization of the Petroleum Exporting Countries (OPEC) was to look to the marginal costsofproduction to support oil prices, progressing from the physical market to the paper market.
