This article proposes a hybrid algorithm for assessing the quality of regulatory legal acts (RLA). This algorithm uses the methods of fuzzy mathematics, processes with their help the results of the questionnaire survey of the expert group. The result of the algorithm is the quality characteristic of the NLA in the form of a fuzzy term of a linguistic variable. As an option for automating this algorithm, a specialized automated system is proposed.

The article considers a generalized algorithm for assessing the quality of socially significant activities (hereinafter referred to as CPAs), which provides for expert assessment and subsequent data analysis using one of the assessment scales (linguistic, point and interval). Methods are proposed that are advisable to apply at various stages of the generalized algorithm. The groups of criteria for assessing the quality of CPAs are determined: deterministic and partially deterministic. It is proposed to calculate the quality assessment of CPAs by summing the values of the calculated deterministic and partially deterministic criteria, adjusted for their weight determined by an expert. When implementing the proposed algorithms, the mathematical apparatus of fuzzy logic was used, which allows us to carry out calculations with fuzzy given input information characteristic of social objects. It is convenient to automate and apply such algorithms when the data is presented in a qualitative interpretation.

In contrast to the classical transport problem, according to the minimum total time criterion, it is assumed that resources are processed both at the source points and at the destination points, the duration of which depends linearly on the volume of the processed batch. This takes into account both the availability of the vehicles involved and their characteristics, such as load capacity. The use of the Hungarian method is justified for the distribution of resources along the available routes. To solve the problem of distribution of available vehicles by starting points, taking into account the load capacity of vehicles, it is proposed to use the method of dynamic programming. An illustrative example and distribution of delivery means using the "Search for a solution" command in MS Excel are considered.

A model that implements a method for assessing the security of a special purpose automated information system is considered in the article. The model takes into account both the intensity of the load on the system and the number of channels as a means of protecting information from DDoS attacks based on the combination of theoretical and empirical approaches to assessing security of special purpose automated information system. The transition from a theoretical model using empirical states and continuous time to a discrete time model is applied to build a new model. The purpose of the work is to develop a model that implements a method for assessing the security of a special purpose automated information system against DDoS attacks based on a theoretical-empirical approach to modeling information protection means against DDoS attacks.The following tasks are solved in the article: analysis of known models that implement the method for assessing the security of special purpose automated information system from DDoS attacks; the model which implements a method for assessing the security of special purpose automated information system based on a theoretical-empirical approach to modeling information protection against DDoS attacks is being developed. The use of the new model makes it possible to apply both empirical values obtained as a result of measurements or modeling, and a theoretical basis for modeling information protection means under the influence of DDoS attacks, taking into account their characteristics, which will be reflected by the income function and the choice of the optimal mode of functioning of the special purpose automated information system in discrete moments in time. When synthesizing the models presented in the article, the lack of the static nature of the assessment of the security of the special purpose automated information system was eliminated, the intensity of computer attacks such as DDoS, which dynamically changes both the parameters evaluating the means of protection and the probability of the system being in critical states, was taken into account.

The article is devoted about the importance and urgency of the problem of reconstruction of healthcare facilities, since hospitals, like other forms of ownership, accumulate moral and physical deterioration and need periodic repairs or full-scale reconstruction. In our country, it is not uncommon for a hospital to be a dilapidated building whose service life is coming to an end. That is why in our days the issue of full-scale reconstruction of healthcare facilities is so acute. The Ministry of Health of the Russian Federation has developed a number of measures, thanks to which, according to Rosstat, more than 10 thousand hospitals will be repaired by 2024. The authors of the article make a comprehensive assessment of maternity hospitals in Rostov-on-Don, show their layout and fertility chart. The following is an example of the reconstruction of the observational building of the MBUZ. In the conclusion, the results are summed up and the measures that need to be taken for the comfortable stay of people in the hospitals of our country are determined.

The problem of digitalization of the data accounting system and the problem of managing the technical condition of equipment at thermal power plants are considered. The performance of the entire thermal power plant depends on the operation of the boiler units. If the equipment fails and the necessary measures to resolve the emergency are not taken in time, then the probability of a decrease in the plant's performance up to the suspension of work increases. Thus, the issue of monitoring the technical condition of all operating equipment is relevant. The developed software for automation of the data recording system and visualization of technical parameters of the reliability of boiler and turbine equipment is described. The software has a methodology for determining the technical condition index of equipment. The software was developed using the JavaScript programming language, the React.js library. Digital technologies have been introduced into the process of recording data on the technical condition of equipment, where for the first time the software includes a method for automatic calculation of the technical condition index of boiler units. The software ensures that equipment downtime is reduced, as well as the likelihood of failure or critical breakdown of boilers. Thus, the operation of the software makes it possible to reduce the likelihood of an emergency state of the main equipment of power plants.

Currently, the problem of increasing the efficiency of managing resource-intensive tasks in distributed computing systems is quite acute. Analysis of existing task dispatching algorithms for traditional computing systems showed the limitations of using these methods in heterogeneous systems, as a result of which significant delays can occur between task switching.A functional mathematical model for estimating the workload of distributed computing systems is proposed, based on determining the probability of downtime of the processing center as a criterion for assessing the system load. Using this model will provide increased efficiency in managing resource-intensive tasks in distributed computing systems.

The article discusses several equivalent circuits constructed by sequentially connecting circuits for the membrane and protoplasm. The solution was made using the Cardano formula for cubic equations. The roots in the expression for the determination of resonant frequencies determined the resonant frequencies for the given parameters for the membrane and intercellular fluid; to obtain numerical values, values ​​were used within several permissible limits.
