This article is dedicated to modeling performance indicators of the comprehensive process of constructing a multi-story building while varying influencing factors, taking into account existing constraints, and utilizing modern software complexes. During the modeling process, the following solution for wall construction was employed as a component of the comprehensive building process: the installation of lightweight steel thin-walled structures (LSTW) with non-removable formwork cladding and filling with polystyrene concrete. Previous research has established that this construction and technological solution is the most effective among the compared alternatives.
Building upon prior investigations, experimental-statistical modeling of the «construction duration», «construction cost», «average intensity of funding», and «maximum intensity of funding» indicators was performed, varying factors such as the «overlap coefficient of processes» and «number of working hours per week». Modeling was conducted using the COMPEX software complex. The values of efficiency indicators were obtained according to selected experimental plans by constructing economic (budgetary calculations) and organizational-technological (work performance schedules) models using the AVK 5 and Microsoft Project software complexes, respectively.
During the experimental-statistical modeling, extremes of efficiency indicators and corresponding values of factor combinations influencing them were determined. The nature and degree of the factors' impact on the investigated efficiency indicators were identified.
The «construction cost» indicator was subjected to an existing constraint in the form of using credit funds. The calculation of the impact of imposing this existing constraint was performed in the Microsoft Excel software complex. While varying the factorial space, diagrams of changes in the budgetary cost of building construction and the amount of funds needed to secure the loan were constructed. Combining these diagrams resulted in values for the «construction cost with consideration of credit funds». It was determined that the use of credit funds at a level of 90% significantly increases the cost of building construction. On average, this increase amounted to 183,8 million UAH.
Graphical dependencies were constructed using the CorelDraw X6 software complex.
