Abstract

The object of research is the processes of operation of a web-based information system. The conducted research is based on the application of existing approaches to organizing the operation of IT products, as well as on the previously developed formal model of the problem of managing the operation of an information system. The existing assessment of the satisfaction degree of the requirements for the system was adopted as the main criterion for managing the operation of the information system. The main hypothesis of the study is the assumption that the main criterion for managing the operation of a web-based information system should be considered the efficiency indicator as the ratio of the degree of satisfaction of requests for changes in individual components of the information system and the total costs of operating the system. The analysis of the applicability of the criterion «Satisfaction of the requirements of users of the information system» is carried out and its incomplete objectivity is shown for describing the goals of managing the operation of the information system. The use of the management efficiency indicator is substantiated, the features of the use of this indicator for solving the problem of managing the operation of the information system are considered. The existence of two approaches to determining the efficiency of the operation of an information system is recognized. Based on the results obtained, a concept for managing the operation of a web-based information system is proposed. This concept represents the main task of managing the operation of a web-based information system as a special case of a multicriteria optimization problem, the solution of which will be a Pareto-optimal system. On the basis of the proposed concept, a mathematical model of the problem of effective management of a web-based information system has been developed. To describe the function of the goal in the course of developing the model, it is proposed to move from descriptions of requirements to knowledge-based models of requests for changing the information system. It is also proposed to divide the set of model constraints into two separate complexes – a set of technical management constraints and a set of operating process constraints. Application of the developed model will make it possible to create new information technologies for managing the operation of web-based information systems for enterprise management. In contrast to the existing ones, such technologies will allow formalizing and automating the work on the formation and approval of the most profitable for the participants in the operation of the information system of project plans for fulfilling requests for changes in the operating system.
