Публікація Algorithm and software of medical personnel selection system(Національний технічний університет "Харківський політехнічний інститут", 2023) Yamburenko, Viktor Viktorovych; Liutenko, Iryna Viktorivna; Kopp, Andrii Mykhailovych; Holovnia, Dmytro MykolaiovychThere is a lot of routine work in any organization, including in recruitment agencies. Effective management organization and automation of activities of employees of recruiting agencies is not an easy task. The system should automate the routine actions of workers of recruiting agencies and be convenient for their clients. This paper proposes an approach to automating the selection of necessary medical staff. Not all information systems used by recruiting agencies can compare candidates and generate results that include several of the best candidates. Based on the analysis of the subject area, groups of parameters that significantly affect the choice of medical personnel were determined. The proposed approach is to analyze the request from the client, and then in the system find requests of other clients similar to it in terms of parameters, for which a candidate has already been found. The next step is to take the profiles of healthcare professionals that have been suggested for these requests (they act as benchmarks) to further compare them with existing candidates. Each employee profile parameter has its own similarity function. Available candidates will receive scores and will be ranked. We also additionally adjust the assessment by comparing candidates with the current request. Software was developed to automate the selection of medical personnel. For its implementation, a three-level client-server architecture is proposed. MVC (Model View Controller) architecture was chosen for the server part. The Single Page Application architectural template is used for the client part. The server part is divided into three layers, which further demarcate and structure the responsibilities of the system components. .NET technologies are used to implement business logic. SQL Server is used for the server and database provider. The use of the software implementation of the developed system demonstrated quite good results. The average time for selecting the 10 best candidates out of 500 is 0.4 seconds, and the processing of only 1 resume by a person takes several minutes.Документ Method of converting the monolithic architecture of a Front-End application to microfrontends(Національний технічний університет "Харківський політехнічний інститут", 2023) Nikulina, Olena Mykolaivna; Khatsko, Kyrylo OlexandrovychWeb systems have existed for a long time and quite a lot of them have been created. Modern development uses new microservice architectural to improve performance, portability, and other important characteristics. This necessitates the transformation of legacy systems from a monolithic architecture to a microservices one. Such a process is complex and costly, so improving the methods for converting old systems to a new platform is relevant. This research aims to develop a method of applying microfrontends approach for monolithic single page applications (SPA). The article proposes a method of transforming the software system architecture from monolithic to microservice architecture (MSA). Since the client part of the system is considered, the term microfrontend is proposed, as an analog of microservers in the server part of the software systems. A brief review of existing architecture reengineering research is made and the advantages of a microservice approach are identified. The proposed three-stage method differs from the methods by the selection of an additional stage of conversion, which allows to gently change the connections between parts of the monolithic application, which were implemented in the initial monolithic architecture. The first stage is reverse engineering, it is proposed to shift the focus from the search for outdated code to the functional analysis of the program as such. The second stage, a transition to a modular architecture with the allocation of functionality into separate modules is proposed. At the end of the third stage, we have several separate programs (microinterfaces) that are connected to the main program. An experiment with a typical external SPA demonstrates the operation of the proposed algorithm. The system obtained as a result of the transformation is compared with the original one according to the following measurable parameters: production builds building time, size of the main bundle, and first page average load time. All comparisons showed the advantages of the system obtained as a result of the conversion. As a result, the architecture transformation algorithm allows you to obtain a guaranteed better result, taking into account the limitations of the interface SPA, which were not considered by the authors of previous articles.
