The article provides a detailed analysis of the well-known mathematical methods that are used in solving transport logistics problems of various types. Their advantages and disadvantages are determined. The article proposes to use the methods of swarm intelligence to find the optimal route, taking into account all forbidden zones. The problem of transport logistics was solved by the ant colony optimization algorithm on a control example. The results of work of the method were analyzed. The main disadvantages are established. It is proposed to use a modification of the ant colony algorithm - the Max-Min ant colony optimization algorithm. The effectiveness of the method for solving the problem of transport logistics by the algorithm of max-min optimization of an ant colony was tested on a control example. An experimental calculation of the optimal route of traffic from the starting point to the final point is given taking into account the forbidden zones.

“…The calculation of the energy performance of a building is only accurate if the tightness of the building is measured [28,29]. It can be measured by various methods: theoretically [30,31], empirically [32][33][34][35][36], or by single-component models [37]. Relander et al tested the tightness of connections between the basement wall and the wall with a wooden structure.…”

The aim of this work is to develop a model of heat supply to buildings with almost zero energy consumption, indicating the significant importance of heat losses and gains in heating installations. The prepared model is to indicate the need for changes in the structure and topology of heating installations, resulting from the changing heat demand of buildings. The need to create a new model is heightened by changes that relate to tightening legal regulations related to energy consumption and demand, which must meet the standards of buildings in Poland from 2021. The article presents the assumptions and results of analyses of the use of energy installations in residential buildings that use renewable energy sources to balance energy consumption in various areas of its use. To achieve this goal, calculations were made using simulations of the impact of the use of installations using renewable energy sources on the energy performance of a building with different quality of partitions and improvement of energy efficiency in accordance with the Polish standard PN-EN 12831. The test results allow to choose the most advantageous, from the point of view of economic profitability, option of replacing installations in residential buildings, and they also allow to determine the possibilities of meeting national obligations in the field of final energy reduction and increasing the share of renewable energy sources in meeting its demand in accordance with the EU obligations imposed on Poland. Thermomodernization of buildings in the temperate climate zone allows for a reduction of 38% of energy demand over the entire life cycle of a building and a reduction of CO2 emissions by 99%.

“…They naturally position the possibilities of improving the areas requiring improvement. The issues of optimization are located in the area of linear programming [1][2][3], where the end result is the achievement of the assumed optimization goal. In practice, the assumed function of the objective may therefore be differently defined, for example, to strive to achieve a certain extreme in the form of minimizing inputs or maximizing profits.…”

“…The results of calculations for 50 possible scenarios related to two types of vehicles i.e., with a capacity of 4500.0 (dm 3 ) and with a capacity of 7500.0 (dm 3 ) are presented in Figures 4 and 5, respectively. Summing up the results obtained for all 50 considered scenarios of the planne flight schedule (Figure 3) and all flight times and frequencies of takeoffs, we concluded that:…”

During aircraft flights, combat readiness and the supply system affecting it are essential issues. The basic items of supply during the implementation of tasks are combat assets and aviation fuel. Effective management of the flow of required products, as well as the reliability of vehicles and the availability of crews contribute to the quality of task performance. The components that make up this quality in military operations are measured by readiness. In real-life operations, the number of vehicles supplying aircraft with aviation fuel is determined for safety and reliability with an surplus related to the number of flight support facilities. This paper develops a method for determining the minimum number of vehicles required to supply aircraft (sp) with aviation fuels. The developed method was verified by a numerical example illustrating its application in practice. Additionally, a detailed analysis of its application was carried out in relation to potentially 50 possible scenarios of combat task execution, with a number of assumptions fulfilled. Based on the performed calculations, it was concluded that the number of vehicles required for sp fuel supply depends on several factors: the number of aircraft, the characteristics of air tasks (flight length and frequency of departures), as well as the time of clean sp refuelling and the duration of the vehicle-tanker refuelling cycle.
