Existing software tools for business process model analysis are based on metrics and thresholds that allow assume presence of errors in business process models, but they are not capable to recommend structural changes required to eliminate detected modeling errors. Therefore, business process model analysis and improvement tasks become relevant, since early detection and elimination of possible errors presented in business process models may allow organizations avoid extra costs that may occur on any of the steps of business process lifecycle. Since business process models are shared organizational assets, it is also necessary to consider the capabilities of collaborative and concurrent usage of business process models by multiple stakeholders. Hence, the workflow of business process model analysis and improvement was analyzed and its key steps, which describe expected user and software behavior, were formalized using the IDEF0 functional model. Functional software requirements were captured in the form of user stories according to modern agile practices of software development. These user stories are based on features and drawbacks of existing software tools for business process model analysis. Captured user stories were formalized using the use case modeling. Non-functional software requirements were also captured; they include maintainability, readability, testability, understandability, integrability, and complexity requirements. Captured requirements can be used to design and develop business process model analysis and improvement software capable to provide recommendations to eliminate detected modeling errors. software tool.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

To build the \"AS–IS\" model, event logs are used, which contain a record of operations with timestamps implemented during the operation of the enterprise. Construction of the process model \"AS–IS\" in the use of logs is performed by means of intellectual analysis of processes. The resulting model of the prototype of the business process has the form of a graph showing all known from the log of events of its implementation. The aim of the work is to increase the efficiency of process control implementation by developing the technology of building prototype models of the process \"AS–IS\" in the conditions of disordered business processes and erroneous input data. To achieve this goal, the article solves the following tasks: development of technology for modeling business process prototypes; experimental verification of technology. The following results were obtained. The technology of automated prototyping of business process models \"AS–IS\" has been developed, which includes the stages of structuring event logs in a process-oriented form and further construction of business process models by methods of intellectual analysis of processes. The developed technology allows to obtain a graph model of a business process prototype, which is used in the implementation of process management within the first and second levels of process maturity. On the basis of the received model \"AS–IS\" the improved process model \"TO–BE\" is formed. The experimental test showed that the developed technology provides the construction of a process-oriented log and the subsequent formation of a prototype model of a business process that reflects the current activities of the enterprise.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

At the same time in the learning and training process, the use of a distributed system has the advantage of data processing: storage of information about students, construction of training courses, verification of passed material, etc. The problems of scaling and efficient use of resources in distributed learning management systems are investigated in this research. Cloud platforms for hosting the system, such as Amazon Web Services, Microsoft Azure, Google Cloud Platform and DigitalOcean are reviewed. Problems and features of a scalability in cloud computing are discussed. Methods, scaling and load balancing algorithms for the efficient use of computing resources are proposed. According to the list of advantages, the DigitalOcean platform was selected for the investigation. DigitalOcean provides cloud servers that can be used for quick creation of the new virtual machines for the projects. These servers allow to fully control the web hosting environment at the same time that the user pays only for the resources used. The main goal of DigitalOcean is to use a solid-state drive (SSD) to create a user-friendly platform that will allow clients to migrate projects to and from the cloud, increasing productivity with high speed and efficiency. As a result of analyzing information on existing technologies, approaches and methods for using cloud platforms in distributed systems, they have been applied to develop a solution to reduce downtime for a distributed adaptive Learning Management System (LMS). It is concluded that the use of cloud platforms for the construction of distributed LMS a practice that allows to use only the required amount of computing capacity. It is proven, that the implementation of the proposed solution into the work of adaptive LMS will improve its efficiency by reducing the time of the content delivering.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".
