Paper covers issues connected to the determination of the technical characteristics of construction machinery unit performing a certain category of work. On the basis of the results of the review and analysis of scientific works concerning the problem under consideration the key disadvantages have been identified for the existing techniques. Optimization model for determination of the technical characteristics of construction machinery unit has been created. Initial form of the model is not linear toward unknown variables but it can be transformed to the linear form that allows application of simplex method for efficient solution of the problem. The created model has been implemented on a practical case – the obtained results indicated the adequacy of the developed tool.
The article presents the development of conceptual models of buildings constructed with using Building Information Modeling software complexes. It describes the advantages and disadvantages of modern additive technologies. Features of their using are specified. Examples of their integration in modern construction are shown. Construction areas for which building models were developed were selected. The main ways of development of construction in the selected areas of activity are indicated. An analysis of current trends in the field of architecture is presented, and a forecast of future architectural trends for the coming decades based on the results provided by 3D Fast Build technology is made. The functional features of the buildings construction of the designated time period are taken into account. They were theoretically integrated into selected objects related to various construction areas, with their further design and modeling in the Autodesk Revit program, taking into account all identified trends and expected functionality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
