Optimization of the characteristics of organizational and technological solutions aimed at reducing the impact of project risks

Abstract

Introduction. The research relevance is determined by the need of modern design and construction organizations to objectively estimate the impact of various categories of risks on the results of the construction projects’ implementation, as well as the limitations of existing tools used to justify the parameters for the implementation of construction projects, taking into account the risks of the internal and external environment. The mentioned above features determined the feasibility of conducting the research, which purpose is to develop the tools for determination of the characteristics for organizational and technological solutions aimed at reducing the impact of risks on the results of construction projects’ implementation. Materials and methods. The methodology of the substantiation of the characteristics of organizational and technological solutions aimed at reducing the impact of risks on the results of construction projects has been developed. The methodology assumes forming the analytical model of dependence of risk indicator value from parameters of the construction project to be realized (risk parameters) with further building and realization of an optimization model to substantiate changes of the ma-naged risk parameters on the basis of criteria of total expenses for realization of the indicated changes and actual values of indicators of negative influence of risk on the results of realization of construction project. Results. The developed method has been realized by the practical example, as a result of the corresponding calculation procedures the values of the parameters’ changes of the operating process of the investment and building organization of the oil and gas sector to provide the required values of the actual average (by objects) term of delay in putting into operation and the share of the objects put into operation on time have been obtained. Conclusions. Based on the results of the implementation of the proposed methodology on a practical example, the conclusion of a high practical significance of the developed tool has been made. The features of the developed method that reduce the area of its effective application have been identified, in particular, dependence of the adequacy of the results of the method realization on the adequacy of the analytical model of dependence of the risk indicator value on the para-meters of the ongoing construction project. For elimination of the revealed disadvantages, the updating of the methodology on the further stages of research is planned.
