. Architecture of an Integrated Information Systems (ARIS) methodology sector has a strategic meaning for the Russian Federation. Role of a rationalization of different transport modes increases significantly due to the fact that it is important part of the market infrastructure, in the context of development the market relations. Undoubtedly, for Russia, which is the largest country in the world, a railway transport is a link of a single economic system, provides a stable activity of an industrial enterprise, provides an opportune supply of an important goods to the most remote areas of the country, also it is the most cheapest transport for millions of people. Therefore, the railway transport is a systemic industry of Russian economic that largely forms additional demand in many related industries and all sectors of economics depend on the work of railway transport. So, the above - listed cause led to selection for this academic project the company of development and maintenance of railways.study of "SetStroyEnergo" organization will be placed on the features of identification and formalization for basic procedure of the organization using a system approach and Architecture of Integrated Information Systems (ARIS) methodology.analyzing the system approach, firstly it is necessary to review the historical background this method of identification business processes.believed that the first step towards the formation of a systems approach for solving problems of the development of mankind made an Austrian biologist and author of "general system theory" Ludwig von Bertalanffy, who in 1941 proposed this term. Bertalanffy published his most important work "General System Theory" in 1969. There he formulated the objective of a new science that is the development of the mathematical apparatus of the study of systems of any physical nature and the establishment of the isomorphism of laws in different areas of knowledge. Such outstanding scientists as Russel Ackoff, U.Churchman, Fred Emery, Jay Wright Forrester and many others also made a contribution to the further development of system theory. However, it should be emphasized that many of the system ideas were expressed much earlier by Russian scientist A.A. Bogdanov in his book "Tectology. Universal Organization Science" (1922).the consideration of the organization as a system is generally accepted. This fact inevitably leads to the necessity of application of a system approach while solving problems related to the study of activity of organizations. Moreover, among managers and consultants there are ambiguous or inaccurate interpretations of the terms "system", "system approach", "business process", different views on the use of scientific methods to solve practical problems related to the activity of the organization.

1. Key definitions

order to make clear the points discussed later in this essay it is necessary to define the basic concepts concerning business processes and system approach. So this paragraph will be devoted to the definitions of the following concepts:

· a system;

· a system approach;

· an organization;

· integrity;

· business processes.primary definition of a system is a set of two or more elements that satisfies the following three conditions:

) The behavior of each element has an effect on the behavior of the whole.

) The behavior of the elements and their effects on the whole are interdependent. It means that the way each element behaves and the way it affects the whole depends on how at least one other element behaves.

) However subgroups of the elements are formed, each has an effect on the behavior of the whole and none has an independent effect on it. Therefore, the elements of the system are connected in a way that the formation of independent subgroups is impossible. [1]to Ackoff, the following important features result from the definition of a system:

• Each part of the system has essential properties that it loses in case of separation from the system;

• Each system has certain essential properties that are not possessed by any of its parts. The essential properties of the system as a whole stem from the interaction of its parts, and not from their actions., when the system is taken apart, it loses its essential properties. A system is a whole that cannot be understood through the analysis. Therefore, an application of a system approach must be started with the stages of synthesis.the assumption of Ackoff's definition a system approach is formed by the following sequence:

• identification of a system, a part of which is a subject that needs to be explained;

• explanation of the behavior or properties of a system;

• explanation of the behavior or properties of a part of the system relying on its role (roles) or function (functions) in the whole that contains this part. [1]first two stages of the system approach are a synthesis of a system. And the method of analysis is used at the third stage. A synthesis is always precedes an analysis in system approach. The method of synthesis focuses on the functioning of the system. It gives understanding (explanation) of the system.is a generalized description of objects with complex internal structure. The concept of integrity expresses integration, self-sufficiency, independence of these objects, their opposition to the environment related to their internal activity; it describes their qualitative peculiarity, due to their distinctive specific patterns of functioning and development. [2]characterizes a qualitative peculiarity of the system, due to its distinctive specific patterns of functioning and development. Integrity reflects the fundamental irreducibility of properties of the system to the sum of the properties
