Two-baffle trap for macroparticles
In this work, properties of two-baffle macroparticle traps were investigated. These properties are needed for designing and optimization of vacuum arc plasma filters. The dependencies between trap geometry parameters and its ability to absorb macroparticles were found.

Comparative analysis of order allocation methods and intelligent systems for effective download of production capacities of manufacturing enterprise
The article compares the planning systems of the enterprise, determines their opportunities to use simulation for the process of distribution of production orders. A comparative review of the methods used in production planning systems and the multi-agent approach in solving the problem of the allocation of production orders is carried out. The possibility of approaches in cases when it is impossible to perform production tasks within the established time frame is considered, as well as to effectively load the available capacities of the units. In case it is not possible to produce the necessary quantity to distribute the part to another, similar to the type of equipment used, but different from it by the quantity and production capacity of the unit. Transmission must be carried out under the condition of sufficient capacity in the subdivision. The results of theoretical and experimental studies are presented. In the process of work, we used the BPsim. MAS dynamic modeling system. An automated system with the possibility of using simulation for the allocation of production orders is considered. © 2019 IOP Publishing Ltd.

Decision Support based on Multi-Agent Simulation Algorithms with Resource Conversion Processes Apparatus Application
Development of Cloud-Based Microservices to Decision Support System
Intelligent systems of simulation become a key stage of the scheduling of companies and industries work. Most of the existing decision support systems are desktop software. Today there is a need to use durability, flexibility, availability and crossplatforming information technologies. The paper proposes the idea of working cloud based decision support system BPsim.Web and this one consists of some set of services and tools. The model of the multiagent resources conversion process is considered. The process of the simulation model developing via BPsim.Web is described.

Development of a method and decision support system for distributing orders of a machine-building enterprise
The efficiency of the machine-building enterprise depends on the efficiency of management decisions at all levels, which affect the implementation of production orders, rational use of production resources. The use of modern information technologies which are based on mathematical methods allows you to make the right management decisions in a timely manner to improve the efficiency of the enterprise. © 2020 Published under licence by IOP Publishing Ltd
Simulation of the steelmaking process using collision avoiding cranes moving models
The paper discusses a steelmaking process and its optimisation using simulation. The optimisation goal is to reduce the total distance travelled by cranes in all spans as well as to reduce the steel waiting time before casting on a continuous casting machine. Models of the process under study have been developed in the AnyLogic simulation software and the modelling subsystem of the metallurgical enterprise automated system. A comparative analysis of the simulation results has been conducted. All results are feasible in terms of meeting the technological constraint on the steel downtime in front of the continuous casting machine for no more than 15 minutes. When comparing two collision avoiding cranes moving models, a choice has been made in favour of a model that provides cranes movement to the nearest steel processing aggregate. Using this model allows to reduce the total path travelled by cranes by 6%. The results of using different modelling systems are consistent. © 2020 Published under licence by IOP Publishing Ltd
