Summary: The article presents the synthesis of a formalized form of integrated algorithms that perform similar technological functions one-party document management in the sector of railway automatics and telemechanics, taking into account peculiarities of their structure. The basic method of combining algorithms is the introduction of additional definitive logical conditions. The developed model provides a reduction in the number of occurrences of the same type operators and logical elements in an algorithmic description of the process of doing of order specifications.

Keywords: technical document management, maintenance of order specifications, formal methods and models, the combined algorithm, the synthesis of the combined algorithms.
