Abstract
Modern technologies requirements aim at improving the efficiency and safety of managing industrial facilities to a sharp increase in the information load of technological information systems (IS). These features of complex TSs are in the context of the general results for studying complex systems, which show that with increasing a complexity of the structure, the share of information contained in the system's connections increases significantly, in order to give a general description of tasks that require joint analysis of the interrelated parameters of complex technical systems and the use of appropriate process models in the TS. The work is aimed to develop methods for the construction and implementation of an analytical information system as part of a technological management system.
