... m must meet during implementation are defined, and the approaches to the development and updating of service standards are proposed. Taking into account the general trend that consists in the increasing amount of information collected and processed from the field level, a variety of technological objects, as well as the increasing autonomy and complexity of control systems, the task of organizing timely maintenance and repair, and processing of the results using traditional methods, is becoming unsolvable. The ensuring of an independent assessment of the quality and timeliness of work, the impossibility of misrepresenting information about the service is becoming the key point to build transparent relationships in service organization. This article describes the methods and algorithms of business processes necessary to design and implement such systems. Based on the described methodology, an information system was developed, and an assessment of the economic effect was carried out using the results of its implementation and adaptation
