In most industrialized countries fixed assets dominate in the structure of national wealth. As elements of fixed assets, the authors of this article consider industrial and non-industrial buildings as part of enterprises of the agroindustrial complex. The study of the effectiveness of building restoration shows that the criteria for effective repair and reconstruction of a building are the maximum reduction in physical wear and minimum capital investments. Based on the analysis of defects in building structures found during the determination of the technical condition of buildings of enterprises of the agroindustrial sector, the article formulates the classification of the most frequent defects that reduce the performance properties of fixed assets of enterprises and sets the mathematical dependence of the physical deterioration of fixed assets from the period of their operation correlation regression equation. Based on the carried-out modelling of the intensity of wear, a system for monitoring the technical condition of buildings based on the so-called "controlled operation" of buildings is proposed in order to effectively use depreciation charges to eliminate physical deterioration of buildings. Based on the results of the study of methods for calculating depreciation and regulatory documents governing the respective service life of buildings, a method was developed to optimize the planning of capital investments to eliminate the physical deterioration of the enterprise's buildings as elements of fixed assets. The application of the developed method allows to increase the efficiency of management decision-making by the management of the enterprise, which has an impact on the effectiveness of the finished product output by enterprises of the agroindustrial complex.

Effective production activities of organizations is impossible without the concept implementation of the constant reproduction of capital assets, a significant part of which is represented by buildings and structures for various functional purposes. Increased deterioration of industrial buildings does not allow to solve such important tasks as improvement and automation of production processes in their entirety, and has a negative impact on the working conditions and safety of personnel. The analysis of scientific and normative literature is showed that the issue under consideration requires further research. Author’s approach to the reproduction of capital assets, the use of which allows to increase the management decisions efficiency on the basis of a complex of tasks for the joint estimation of damage and deterioration, planning of works under the given constraints with the use of mathematical apparatus and technological solutions for monitoring the technical condition of buildings is presented in the article.

Surveys performed nationwide show that mobile temporary accommodation camps are being manufactured by more than 200 specialized enterprises (without considering the minor manufacturers) acting under different ministries and agencies. According to the analysis performed, today 26 basic mobile structural systems consisting of 18 conveyor-type and 8 demountable-type systems are being used on a national basis. Today national manufacturers are producing more than 250 types of container-type buildings and facilities which differ in functionality, capacity, climatic category, price and other technical-and-economic indexes. Use of mobile accommodation complexes is characterized by certain advantages. Basic criterion for mobile accommodation camp construction consists in its timely commissioning. Basic predicted indexes affecting the cost of temporary accommodation camp could serve as an endorsement of the forwarded standpoint.

This article is devoted to structural scrutiny of a building. The technical condition of buildings affects such characteristics of a building as safety, reliability, durability and maintainability. However, in the absence of reliable information on the technical condition of buildings, structural survey or monitoring of а building in order to determine the category of technical condition is necessary. The purpose of this work is to develop an economic and mathematical model for determining the type of maintenance work based on the results of structural scrutiny and monitoring of a building. The article is of importance because the final stage of the survey gives a qualified opinion on the level of structural scrutiny of a building, and on the basis of this opinion repair work eliminating physical and moral deterioration and providing in accordance with specifications renovation of the building are planned. The scientific novelty of the economic and mathematical model developed by the authors on the results of building structural scrutiny lies in the application of the fuzzy set theory and fuzzy logic method for determining of the level of physical and moral deterioration of a building consistent with a certain type of repair work and followed by the necessary capital investments.
