"This article describes the application of the ontological approach to the creation of an intelligent system of recommendations in the work of military recruitment committee. A popular and perfectly proven approach to describe and represent knowledge is ontologies. Designing knowledge-based systems is impossible without a thorough systematic study of the subject area in which the problem is to be solved. The result of systems research should be represented by the formalism best adapted for further implementation. Ontology is such a formalism, and this article discusses approaches to the formal representation of ontologies as the most important mechanism of knowledge engineering. Conceptually, ontology design processes are similar to those with multi-agent systems. In this case, nodes or agents connected to each other materialize our knowledge of the problem solution. An agent is comparable to the notion of an entity in an ontology. In both cases, an ontology graph is used. The Protégé software platform was chosen as one of the most popular development tools to implement the ontology ""Military Recruitment Committee"". An important factor is the support of SWRL, which is necessary for the future development of the project. In the process of ontology design, three main branches of entities were identified: questionnaire data; medical data; psychological data. Based on the results of the logical inference, a recommendation (advice) is formed regarding further decisions (actions) on working with a conscript. The SWRL is used to create rules for checking the set of properties for each conscript, on which a verdict is made. If necessary, the system will explain its actions. As a result, a preliminary ontological graph of the investigated domain in the OWL language is made. Implemented some software modules. Conducted a logical inference on the Protégé platform based on the description in SWRL language of the rules reflecting the impact of the set of entities of the ontology on the inferred recommendations."

Different types of management structures used in enterprises are considered. Such structures are traditionally divided into three types according to the number and types of control relations. A basic dynamic incentive model with the simplest management structure, which includes one Principal and one agent, is presented. The basic dynamic model of stimulation is based on the static model, its solution having already been found. To reduce the number of experiments, the method of qualitatively representative scenarios for finding optimal inputs has been used. Experimental results for the basic dynamic model are presented. The simulation results allow us to determine the solution of the problem in the dynamic form, and provide a foundation for future research using other more complex control structures.

International transport-logistics corridors represent the most optimal routes in terms of structure and direction for the spatial movement of goods by various modes of transport. The routes of international transport-logistics corridors pass through the most rational directions. International transport-logistics corridors are the result of integration of the transport systems of neighboring countries into a common single common route. They pursue the goal of ensuring sustainable and reliable transportation of goods both between the countries participating in international transport and logistics corridors, and in the direction of other countries. This ensures the economic efficiency of joint transportation of goods. Therefore, international transport -logistics corridors perform an important transit function, ensuring the passage of large trade and logistics flows. In order to systematize various types of international transport and logistics corridors, their typology is being carried out. The authors of this article consider various types of international transport-logistics corridors, identified according to the most important criteria. According to the purposes of creation and the economic functions performed, transit, developing and trade international transport and logistics corridors were identified. According to the type of communication carried out, the corridors are represented by various types of land, water and air transport. On a spatial basis, trans-European, pan-European corridors, trans-Asian and North American corridors are distinguished. According to the type of transportation, corridors are classified into freight, passenger and cargo-passenger. Depending on the ratio of the parties involved, the corridors are two-sided, unequal and one-sided.

A modernized approach to project management using calendar and network planning is proposed, in particular, the issue of managing schedules in conditions of uncertainty is touched upon. The proposed approach allows us to take into account the factors influencing the timing of the project and, based on their consideration, take appropriate measures to ensure that we do not deviate from the specified construction deadlines. The proposed approach is based on the methods of Eisenhower matrices, which allow taking into account the degree of influence (vertically) and importance (horizontally) of each of the criteria, and the methods of subject-oriented management, which allow to exclude subjectivism in conditions of uncertainty by excluding manipulations of the external environment, and also include procedures for ranking and selecting factors influencing expert decision-making.
