“…For the selection of variants of different solutions in logistics systems, multi-criteria assessment methods are applied; they use unit costs for this purpose but can also include various technical and operational or ergonomic criteria. Experiments and computer simulations concerning supply chains are carried out [5], and also in the context of gradually implementing potential economic, social and environmental factors for development of sustainable products [6]. However, classical optimization methods focus on one criterion for evaluating solution variants.…”

The transport of the winning in deep mines, using the room and pillar mining system, is most often performed with bucket loaders and haul trucks. In the era of attempts to stop rapid climate change, it is crucial to choose the transport means for the winning both in terms of efficiency and cost-effectiveness and to consider its environmental aspect. Permissible levels of pollutant emissions in exhaust gases are defined for this type of means of transport by the EU Stage Standards. There is a discernible need to develop a multi-criteria method supporting the decision-making process, which should reward loaders and haul trucks that meet more stringent emission standards. The article proposes an innovative idea of taking environmental aspects into account when selecting loaders and haul trucks for excavated material transport tasks, so that the amount of pollutants emitted by them in exhaust gases, e.g., the sum of hydrocarbons and nitrogen oxides (HC+NOx), is also taken into consideration when assigning means of transport to particular tasks. Based on simulation studies for a specific case, it was found that a 20% reduction of HC+NOx emission is possible with only a 2% increase in the transport costs of the winning. For this purpose, an objective function was used formulated on the basis of two criteria: minimization of the transport cost of the winning and the level of pollutant emissions in the exhaust gases. Since dozens of mining machines are operated continuously in deep mines of non-ferrous metal ores, the application of the proposed method would significantly reduce the emission of pollutants in the used air coming out of ventilation shafts.

“…[…]; (3) the survival time of the examined objects is the total operating time; (4) The data covers the period 6 months; (5) the initial event is the starting point of observation of a simulated process; (6) the final event for the object is the end point or the end of the study [11]. For work purposes, the number of simulated orders has been unified by adapting it to the number, which correspond to the number of orders in second and third simulations.…”

The article presents issue of survival of simulated supply chains depends on the complexity of this chain. Authors analyzed the supply chain with mechanism of coordination of actions. In this article, authors decided to compare three supply chain on a different levels of complexity. For each of this supply chain the simulation model was built, and then the analysis of survival was made. In every model authors analyzed the decision part and transportation part. The first model is the basic simulation model with using the Electronic Bulletin Board, in which one contractor was considered. In second model authors extended the numbers of entities (contractors) in analyzed supply chain to four. In third model the transportation part was extended to be more complexitydifferent contractors can realized the transportation tasks. For each case authors focus on aspects of durability of supply chain as non-renewable systems.
