Abstract
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.
Highlights
When using network models in scheduling, there are four main types of dependencies, like “start-start”, “start-finish”, “finish-start” and “finish-finish” [1]
Due to the peculiarities of the technological processes of the work performed in solving optimization problems on schedules, the duration of the work that does not have time reserves should be reduced, otherwise it is
Consider the algorithm for solving the problem using the example of a network model (Fig. 3)
Summary
When using network models in scheduling, there are four main types of dependencies, like “start-start”, “start-finish”, “finish-start” and “finish-finish” [1]. The most common dependencies are “finish-start”, that is, the end of a previous work (finish) makes it possible to start a subsequent work (start). These dependencies may be mandatory (fixed dependencies) or advisory in nature, i.e. may be violated. Taking into account the nature of the dependencies between individual works affects the entire complex of works of a construction enterprise
