Organizational and technological reliability of complex buildings with recourse supply risks modeling

Abstract

Introduction. In recent days, the resources of a construction project (СP) are limited; therefore, the main tasks of managing the resource supply of construction production (RSСP) are optimal planning of resources and management of material and technical support. This includes managing the resources, supply, inventory management and distribution of resources by type of construction and installation work (CIW).Materials and methods. For a systematic analysis of the functioning of a construction project, organizational and technological subsystems are identified that have the greatest impact on the quality and reliability of construction systems. These include construction scheduling, resource support for construction and estimates that determine the cost characteristics of construction production.Scientific novelty. As a criterion for determining the effectiveness of the construction process, the article proposes to use the organizational and technological reliability (OTR) of complex development, taking into account resource supply. The article examines the factors influencing this criterion, as well as determines the indicators of factors and the interval values of the risk assessment of OTR. The values of the OTR indicator are obtained, which is the probability of completing the project on time, and the classification of factors affecting OTR is supplemented.Results. Contractors and developers provide construction facilities with all necessary resources according to the technological sequence of production of the CIW, established calendar plans and construction schedules. The organisation of complete supplies of resources through enterprises and divisions of production and technological equipment, as well as production and acquisition bases will provide for the redistribution of necessary resources to fulfill the production program between the construction sites of complex development.The novelty of the study lies in the modelling of the organizational and technological reliability of complex development, taking into account the risks of resource supply.Discussion and conclusion. To ensure successful resource provision, it is necessary to take into account the risks and take into account, within the framework of information programming, the organizational and technological reliability of the technological processes of the construction project, taking into account the specific conditions and factors of the implementation of the integrated development project.
