Changing the business model of IT management at environmental enterprise in connection with the development of service-oriented information technologies

The article offers approaches to building a business model of IT management at an enterprise that deals with the tasks of nature management, taking into account the needs of departments in modern service-oriented information technologies. To increase the efficiency of IT implementation in the enterprise, it is proposed to use the COBIT 5 methodology, which helps companies to achieve optimal efficiency from IT implementation, maintaining a balance between receiving benefits and risks and resources optimizing. The implementation of the methodology will provide an opportunity to manage and control IT throughout the enterprise, both in the field of functional responsibility of IT and business, and also allows to take into account the IT needs of internal and external stakeholders. However, each company must build its own purpose, specifying and detailing it in accordance with the balanced performance maps (finance, customer, internal management and training and development), in addition, performed the task of effective IT implementation associated with development priorities of business. In this case, the task of approving the decision is multi-criteria. Therefore, special attention deserve issues as finding reasons of such multicriteria and the possibility of using appropriate mathematical methods for the purpose of the cascade. The next reason for the multicriteria of decision-making tasks is the influence of time and space. The concrete implementation of decision-making principles is offered in the form of algorithms or procedures for solving multicriteria optimization problems. Almost all known approaches to solving these problems involve their scalarization. Thus one of the main issues is the list of preferences of the person who makes decisions in choosing the best solution. In accordance with this principle, the methods of solving problems of multicriteria optimization will be classified according to the characteristics of the information: decision-making under conditions of certainty; decision-making in the absence of information about the system of preference of the decision-maker; decision-making in the conditions of gradual receipt of information about the system of preference of the decision-maker.
