Calculation of residential complex payback under the organizational restrictions

Problem statement. The volume of civil construction in Ukraine is constantly growing, while the conditions for this construction are more complex than other types of construction. There have not found exhaustive system recommendations on the choice of organizational and financial decisions on this topic in studied normative and reference literature. The high social, economic and technical effect of solving the problem of choosing rational organizational decisions in civil engineering determines the high relevance of the research topic. Purpose. To develop a methodology and to present the results of the calculation of the payback period of a residential complex for variant that is the most efficient according to the criteria of duration and budget under the conditions of organizational constraints. Main results. Analysis of information sources has shown that housing construction conditions are extremely variable, so it is important to study the impact of changes in organizational decisions on key indicators, primarily on the budget and duration of construction. The method of optimization of organizational decisions of housing construction using modern software products from the field of project management was developed. Through the organizational modeling in the MS Project program and economical mathematical modeling in the MS Excel package, reliable models of the construction process were built. According to the experiment plan, the values of the indicators were fixed and the polynomial model was selected according to the experiment plan. On this basis, experimental-statistical models of indicators variation from variables were constructed. The most efficient models of construction were determined graphically in the limited conditions of their implementation. Conclusion. The proposed technique can be used for other residential complex project designs, and the built experimental and statistical dependencies have allowed the determination of the most efficient option for the construction organization under the working restrictions.
