The article describes the features of usingо information systems and technologies for inspection of buildings and structures. The author notes that the main criterion for making decisions about the need for major repairs or the recognition of the building as an emergency is the category of technical condition of the building. To assess the category of technical condition of structures, conducting a survey of real construction objects, you need to take into account a number of possible reasons that lead to a change in the category of technical condition. Collecting informal information into the knowledge base is a strategically important and most difficult task in the development of ES. Sources of knowledge can be defined as an extensive base of practical and theoretical research in the framework of technical diagnostics of buildings and structures, regulatory documentation, a set of heuristic knowledge and reasoning of specialists. The ability to automate the solution of tasks of expert activity in the framework of diagnostics of building structures in conditions of uncertainty should be sought in the field of artificial intelligence systems. Decisions are influenced by the objectivity and reliability of information provided by experts, but often such information is influenced by their subjective opinion. The use of information technology allows you to take into account the diversity of individual opinions. Among the advantages of using information technologies for building surveys is that the contractor can track data collection in the "field" conditions on the site; the productivity of work increases due to the fact that the time for collecting and subsequent processing of information is significantly reduced; the accuracy of monitoring a number of parameters (geometric, structural) increases and it becomes possible to automate the process of obtaining information about the object, as well as calculating and evaluating the strength characteristics of the studied building structures. These technologies allow us to give a strict mathematical description of vague statements about the technical condition of the building at the moment.

Categoiy of technical condition (normative, workable imited operational or emergency), which is determined by engineering inspection of buildings and structures, is the main criterion in making decisions about the degree of accident or the need to take measures to bring it to further use. The decisions taken depend on the objectivity and reliability of the information provided ty expertswhich sometimes cannot be interpreted as completely true or complete^ false. It seems advisable to strengthen and expand the professional capabilities of specialists who are engaged in the survey of construction sites through the use of expert systems on the basis of the mathematical apparatus of the theoiy of fuzzy sets and fuzzylogic. This makes it possible to take into account the scatter of individual opinions. Information from the subject area of technical diagnostics of buildings is formalized in terms of fuzzy sets with the use of membership functions created for both input and output control parameters. To implement the fuzzy logical inference, Mamdani's algorithm, modified and adapted to the given problem, was proposed. This technology allows to give a strict mathematical description of vague statements realizing an attempt to overcome alinguistic barrier between a person whose judgments and assessments are approximate and indistinct and a computer that can on^ perform clear instructions. A computer program has been developed that implements the method of identification of the category of technical condition of building structures on the basis of fuzzy knowledge bases.

Development and practical implementation of the enterprise industrial safety management system considering the new requirements of the legislation on creation of the state system for monitoring, remote control, technical certification, and diagnostics of technical devices at hazardous production facilities supervised by Rostechnadzor is discussed in the article. To perform automated collection, recording, generalization, systematization, and evaluation of the information on the parameters that characterize safety of the enterprise hazardous equipment as a whole and each technical device, a block diagram of the enterprise automated industrial safety management system is proposed. The basics are suggested for creating the automated system containing a database that includes all the technical documentation, certificates and expert opinions, repair documentation and accompanying documents (orders, instructions, audit conclusions, etc.) for the efficiency of tracking the technical condition in real time considering changes in all the controlled parameters of the enterprise technological complexes. It is noted in the article that the assessment of the technical condition and life of single and unique technical devices that make up the bulk of equipment in hazardous production should be carried out already at the manufacturing stage by combining technical control with technical diagnostics, and their results should be included in the technical passport of the device. The need in this information for the operators is invaluable, especially after working out the manufacturer’s designated period of safe operation and for evaluating the actual technical condition and comparing it with its original, which was documented during fabrication. Data on the initial state allows to qualitatively assess the degradation processes that are developing during operation and consider them when evaluating the life of a technical device and conduct a qualitative audit of the industrial safety management system.
