The main purpose of modern information systems (IS) is to support the procedures of controlling many business processes (BP) of an enterprise. At the same time, due to a weak formalization of BP, processes of development, reengineering of various service-oriented IS and IT services are a complex problem. To address this problem, the task to improve the method for choosing IT services that meet an assigned set of functional and non-functional limitations was stated. The specific features of the original method for choosing IT services were analyzed, its main shortcomings were identified. The model of the BP precedent was modified to establish the relationship between descriptions of the precedent, functional requirements, and the used IT services. The method for selecting IT services for the IS was improved by adding the functions of requirements analysis and searching for descriptions of IT services that partially meet the stated functional requirements. In the method, the adaptive linear associator of the mADALIN neuron was used to quantify the degree of match of the functional requirement and the description of the function of the IT service. These proposals were the basis for the improved method for selecting the IT service that best fits the set of constraints that are formed. Based on the result of the conducted research, an experimental test of the improved method for selecting an IT service to solve the problem of automation of the activities of sale force of the electronic policy OSAGO was carried out. The information technology implementing the original method for choosing IT services was compared to the improved method. It was shown that the improved method makes it possible to identify situations of a match of functional requirements of a customer and the descriptions of IT services. This makes it possible to select those IT services that match the functional requirements to a degree above the assigned minimum limit

The model of the event log of the information system has been improved. The model contains the sequences of events consistent with implemented sequences of management actions within both the process approach and functional management approach. A strict linear order in time was assigned for each pair of events belonging to the same process. The model is designed to describe the prototype of the as-is business process. A case-based model of a business process, describing the features of its known implementations, reflected in the event log, has been proposed. The model combines a set of implemented sequences of operations of each process and takes into consideration the time to implement these operations, as well as the resources they need. When describing the time to implement the operations of a process, delays in accessing the company’s shared resources are taken into consideration. The model makes it possible to predict the terms of completing the set of business processes competing for the resources when removing or adding new processes to this set. The technology for changing the sequence of access to resources for a set of business processes competing for these resources within the process management was developed. The proposed technology uses the case-based model of a business process to calculate the order of access to resources. The technology provides an opportunity to calculate the total reduction in delays over the implementation time in relation to the implementation terms when processes are competing for resources. The technology makes it possible to choose how to access resources with the least delay in relation to operations completion deadlines for the known variants of a business process implementation. This enables a DM to assess the possibility of launching new processes that use shared resources by reducing the waiting time when accessing these resources
