Abstract
Purpose. This paper presents the innovative scientifically-based method on efficiency evaluation of the building production management for contracting companies. Otimisation models are substantially aimed at reducing the influence of negative factors and increasing the quality indexes of the organisational process of construction production. Methodology. Methodological approaches of the organisational processes optimisation of construction production are based on the establishment of a well-defined interconnection between the units of the functional structure, the definition of strategies hierarchy of the contracting company.The correlation of duration t and cost c in building production, its influence on the economic appropriateness for projects realisation in civil engineering are analyzed. Findings. Using mathematical analysing methods for cumulative distribution function S(t,c) of two-dimensional random value of construction duration and cost, the basic principles are shown that allow to qualitatively and quantitatively determine the level of influence of the construction market external factors on the implementation of organisational processes in the construction industry, in which a large number of forming elements are involved. The implementation of this methodology permits to assess the real state of organisational processes system in building production, its stability, the degree of determinate indicators structuring in a single functional system, to generate an economic justification in complex. On basis of simulation modeling, efficiency of organisational processes system in building production S(t,c) was determined and graphically illustrated. Originality. The results of the present study demonstrate that it amounted to 58.08 % within the established limits of acceptable risk (LAR) between 0.35 and 0.65. Practical value. It has been shown an implementation practicability of using this methodology by contracting companies at decision-making stage for construction projects initiation with determinate indicators of duration Td and cost Cd. The creation of theoretical and methodological foundations for the development of structural efficiency evaluation algorithms for the organisation of construction production will allow to achieve for contractor companies the highest level of competitiveness in the market of construction services.
