The article deals with the study of impact of organizational and technological factors on the index of recon-struction profitability of dwellings of first mass series on condition of habitants’ eviction while doing operations. We find lack of information on the methodology of the study of such objects in informative sources . Factual dwellings’ reconstruction has an incidental character and does not allow to define the impact of factors on the indexes of reconstruction because it takes place by fixed values of factors and limited quantities of objects. And as a consequence we find investors’ unwillingness to put money into the reconstruction of the dwellings of typical series. The purpose of the study is to define the efficient solutions of reconstruction of the dwelling of typical series 1-4382.5-7. The given task is solved by making abstract models of the series imitating reconstruction’s operations by simultaneous impact of organizational and technological factors. While conducting the investigation we defined the factors and the levels of their variation that have impact on the dwellings’ reconstruction. The plan of multiple experiment was elaborated considering the simultaneous effect of the given factors on reconstruction indexes. On the basis of the given series of dwelling we made informative and graphical models, and we also got the indexes of reconstruction. Graphical modeling allowed to obtain numerical values of operations’ durability. Simultaneous impact of factors and the conditions of habitants’ eviction defined numerical value of operations’ cost. With the help of formula we obtained the value of profitability index. We defined the dependency of profitability index on varying factors using the methods of mathematical analysis. It is shown in the form of dependency charts and is described by mathematical formula. We substantiated the admissible numerical values of profitability index of reconstruction of the dwellings of first mass series. The conclusions about effective solutions on reconstruction of such dwellings are made by graphical image and the areas of effective solutions are definedKeywords: factors, reconstruction indexes, reconstruction models, mathematical analysis, charts of dependency.
