Patient routing is a key tool for ensuring the availability and quality of cancer care, ensuring early detection of pathology and timely treatment. Mathematical and simulation modeling methods allow to predict the bottlenecks of patient flows and plan the optimal distribution of healthcare resources. Goal to optimize patients’ pathways for oncology care using the simulation modelling methods. Materials and methods Patient routing was presented in the logic of discrete events, the average resource utilization, the patient’s stay time were described, the bottlenecks of the system were determined. Simulation modeling methods were used to build the optimal organization of oncology care services in the region. Results The average waiting time at the pre-hospital stage was 10 days, the average hospitalization time for X-ray therapy was 24 bed days, the throughput of the X-ray therapy room was 6 patients per week, the average duration of the X-ray therapy session per patient was 10 minutes. With the help of simulation modeling methods, a multimodal system of oncodermatology care was created and put into practice, which allowed to reduce the patient’s waiting time for treatment to 0.7 days, increasing the throughput of the entire system.

The investigation results of the applied simulation modeling programs market from the point of view of the usage possibility and expediency at the development or optimization of technological processes on domestic machinebuilding enterprises are presented. The analysis of the technological processes features in machine-building, and in particular aircraft construction, at domestic enterprises is carried out. The production features of the metalconsuming products and semi-finished products from the point of view these processes simulation expediency are considered. The expediency of carrying out simulation modeling of machine-building production, which provides adequate analysis results at minimal costs in comparison with other modeling methods are shown. The main criteria for choosing of specific simulation software are given. Keywords mechanical engineering technologies; metal-intensive production; aircraft construction; deformation processing of metals and alloys; foundry; equipment productivity; optimal stocks of semi-finished products; insurance stocks; simulation modeling; visualiz

This article is devoted to the study of the use of mathematical hardware in the efficient organization of the system of servicing motor vehicles. Herewith, simulation modeling methods enable obtaining information about the state of the system analyzed with the application of its programmed model. This information is then used in the design of system management. In addition, proposals have been developed to improve the car maintenance process within the framework of generating random values corresponding to the distribution of probabilities by type of service over the period of entry into the car maintenance system.
