Optimization of the organizational and technological models of the construction and installation works according to the criterion of minimum duration

摘要

Due to the organizational and technological project, the selection of the optimal parameters of technological processes can be based on the results of numerical modeling of various options for the production of construction and installation works. The aim of this study is determination of the optimal sequence of construction and installation work by modeling the selection of options for the production of works. Research methods include analysis, description, measurement and comparison, as well as the application of scientific knowledge in the theory and practice of building network models. The modeling of the various scenarios of the construction and installation works allows efficient use of the resources, based on such network models. The project scheduling by formalizing a path-float-based approach was analyzed. As a result of the analysis of models of organizational and technological design of construction production, it was established that on their basis it is possible to control the temporal characteristics of both individual and complex work performed. In our research, the extended network model of the object in construction with the dependency "finish-start" was applied. One of the important tasks is to ensure the total duration of the construction during the scheduling.
