Russyi V. Optimization of organizational and technological solutions for the restoration of damaged brick buildings

The object of the research is the process of restoration of damaged buildings and structures. The aim of the work is to determine the optimal values of indicators for organizational and technological solutions in the restoration of war-damaged brick buildings, taking into account existing constraints. Research methods. The dissertation research utilizes numerical modeling methods using modern computer programs. The analysis of the effectiveness of structural and technological solutions for the restoration of major damages to brick walls was carried out using multicriteria analysis. The process of searching for zones of optimal values of restoration indicators is preceded by the creation of numerical models. This is followed by experimental-statistical modeling according to selected experimental plans. The theory of experimental design allows for the maximization of the experiment's efficiency by reducing the number of data points while obtaining adequate results. Analytical and graphical dependencies of restoration indicators on influencing factors are obtained, studied, and optimized considering the specified constraints. The obtained results determine the most effective structural and technological solutions for restoring major damages to brick walls. Analytical and graphical dependencies of the change in restoration indicators within the levels of variation of selected factors are established. Optimal organizational and technological decisions for the restoration processes are determined, along with corresponding zones of restoration indicator values and optimal combinations of influencing factors. The technical and economic efficiency of the conducted optimization is determined. Based on the research results, a technological map for the restoration of the main types of damages to brick walls and recommendations for the optimization of brick building restoration processes have been developed. The effectiveness of the conducted research has been confirmed during the implementation in a number of construction companies. The research results have been utilized in the educational process and scientific work at the Odessa State Academy of Civil Engineering and Architecturе.
