The probabilistic nature of construction production, which is the action of a large number of random factors on the progress of construction and installation works in the construction of housing projects. The duration of construction and installation works in most cases is carried out using deterministic methods that do not take into account the probabilistic nature of construction production. Methods that, in one way or another, when determining the duration of construction and installation works, take into account the probabilistic nature of construction production, focused on the organization of construction in the context of centralized planning of the administrative-command system for managing construction. These methods cannot ensure that organizational and technological conditions for the implementation of construction and installation works and market relations are taken into account, which makes it impossible to justify the duration of housing construction work with a sufficient level of reliability. Improving the reliability of the justification of the duration of housing construction can be achieved by determining such a duration of work, taking into account the organizational and technological conditions for their implementation, a probabilistic nature builds.
Analysis of organizationallytechnological terms of implementation of building and installation works at the use of the specialized brigades, in accordance with concepts accepted in the theory of mass service, allowed to define that this process can be approximated by the queuing system without a mutual help (the amount of channels of service coincides with the amount of requests) from pyasonivskim by the input stream of requests and exponential or еrlangivskim of the second order by distribution (depending on the type of building and installation works) of service a stream.The optimal duration of construction and installation works is recommended to be determined on the basis of calculating the optimal indicator of the intensity of their implementation using the mathematical apparatus of the queuing theory.
