DETERMINATION OF TARGET FUNCTION FOR SUPPLY OF MATERIAL RESOURCES IN THE CONSTRUCTION INDUSTRY CONSIDERING THE PHYSICAL CONDITIONS

Abstract

Purpose. Compilation of the formula of the objective function to determine the cost of transportation of material resources from supplier to consumer (construction site) taking into account the possibility of loss by material resources of their initial physical qualities, which increases the cost of transportation of material resources and the entire construction. Methodology. After analyzing the existing algorithms for determining the target function for the supply of material resources from supplier to consumer, it was concluded that existing algorithms do not take into account all the features of the construction industry, especially the possibility of loss by material resources of their physical characteristics. The need arises for a target function compilation that would make it possible to determine the cost of transportation of material resources with the possibility of repeated or partial supply of material resources. Findings. The results of this work are the analysis of schedules for the supply of material resources from supplier to consumer, taking into account the possibility of the schedule to go beyond the maximum and minimum time of transportation of material resources. There was a complex target function was compiled for the supply of material resources from supplier to consumer, with the possibility of taking into account the re-supply of material resources, or partial re-supply. Scientific originality. This algorithm for determining the target function for the supply of material resources with the possibility of losing their physical qualities in the construction industry was developed for the first time. Practical value. This algorithm allows to determine the real target function of supply of material resources to the construction site with additional costs from the loss of material resources of their physical qualities.
