Abstract
ENG: This article considers deterministic (e.g. the exact time at which to deliver the goods, dimensions and characteristics of
the vehicle, route length, waiting time in line, loading and unloading time) and non-deterministic factors (e.g. transport
breakdowns; accidents; weather conditions; the time that the vehicle is at the consumer’s after unloading; downtime due
to non-payment; breakdowns of machines and mechanisms; low-quality materials; delays in subcontractors) that affect
the time of transportation and the time of the beginning of the use of material resources.
Having identified the main deterministic and non-deterministic factors, it was made the analysis of existing models for
solving the problems of organizing the provision of construction facilities with material resources without delays in time.
It was determined that the existing models could not fully solve the problems associated with the peculiarities of the
construction industry. The following factors are not taken into account: random factors that affect transportation, which
increases the maximum cost, the specifics of the construction industry, which leads to inconsistencies, and as a
consequence, the false results of the objective function.
Schedules were drawn up for the supply of construction resources by the transport organization and the use of
the resources mentioned by the construction organization, taking into account random factors that affect the time of
transportation. By intersecting these two graphs, two main equations that affect the time of transportation and the time of
commencement of material resources and the relationship between these equations were identified.
Based on those equations, two target functions were drawn up, one of which takes into account the additional costs of
the transportation organization logistics and the time for waiting for transporting, the other takes into account the
additional costs of the construction organization for delays in starting work.
