Subject: due to the existence of shabby and hazardous dwelling, the housing problem is one of the most relevant problems in the social sphere of the Astrakhan region. The Astrakhan regional construction cluster includes the significant number of the construction organizations, the servicing organizations, which are engaged in the training of personnel for construction, the banks and other credit institutions, which provide the population with mortgage loans, and also regional, municipal authorities and public organizations. The regional construction cluster is the developing social and economic system of heterarchical type. The heterarchy combines both elements of hierarchy and elements of the market relations. Therefore, the task of creation of a common information space of a regional construction cluster on the basis of mathematical, functional and information-logical models is relevant. Research objectives: use functional and mathematical modeling of heterarchical system of a regional construction cluster for development of its information portal. Materials and methods: for creation of structurally-functional model of a regional construction cluster, the methodology of structural analysis in notations of IDEF0, IDEF3, Swimlane was used. As a tool for structurally-functional simulation, we used CASE-tool - AllFusion Process Modeler r7. The mathematical description of logic of regional construction cluster management is based on the theory of sets. Results: the complex of functional models with the set-theoretic description of the system was developed. The business-process model in a notation of IDEF0 well reflects the process hierarchy that best describes the hierarchical communications prevailing in stable functioning of the regulated processes. For its creation the SADT technology was used. When the external disturbances affect the socio-economic system (SES), inertial hierarchical management ceases being effective and the advantage is given to horizontal managing directors of communication for description of which and for reflection of logic of processes it is more appropriate to use the model of the IDEF3 notation. For explicit description of roles and responsibility of performers of specific processes, it is expedient to use the chart SwimLane, which is variety of the chart IDEF3, in order to achieve the unified information environment of a regional construction cluster. The logic of process interaction reflected in the chart SwimLane was described mathematically by creation of a set-theoretic model. Conclusions: All developed models form a basis for further information-logical and physical design of the unified information environment of the Astrakhan regional construction cluster. Computer support of the functioning of such a complex system will allow us to considerably increase its efficiency.

The article focuses on identification of (1) the level of damage of structures exposed to fire loads and (2) their “residual” bearing capacity in the aftermath of fires. Silicate brick masonry is selected as the sample cladding structure. The co-authors have developed model parameters for the gas medium in case of a fire developing into a system of adjacent rooms. The model helps assess the pattern of development of factors of fire hazards and determine the temperature effect produced on structures, depending on the gas medium density in the room needed to identify the post-fire technical condition of elements of buildings made of silicate bricks and to assess the feasibility of their further operation.The authors employ mathematical models to obtain simple calculation methods aimed at determination of the extent of structural failure (bricks) and the “residual” bearing capacity of structures to:provide their recommendations to fire departments;determine the true limits of the fire resistance of building structures within the parameters of a ‘real’ fire, calculate the required thickness of flame retardants;make inspection of structures after a fire in order to assess the feasibility of their further operation, if visual inspection of the extent of destruction is impossible;depending on the extent of damage to the masonry, make adequate decisions concerning the structural restoration.
