The paper covers issues connected to the determination of most preferred values for the parameters of construction processes implemented with application of sliding formwork and defined by the factors of stochastic nature. On the basis of the review of different literature sources connected to the modeling of mentioned above processes it has been concluded that existing scientific developments provide relatively low adequacy of the results due to the simplified mathematical models that do not take into account stochastic factors. That circumstance has determined the necessity for creation of stochastic model for the construction process implemented with sliding formwork. The initial data for the model include baseline duration of the wall construction process, wall height, concrete layer thickness, characteristics of stochastic values of the concrete layer’s pouring and maturing duration (mathematical expectation and mean-square deviation), etc.; parameters to be determined are the sliding formwork’s panel height and movement base (average) speed. The created model has been implemented on the practical example – wall construction process as the element of the project “Arctic NLG 2”. On the basis of the received results the conclusion has been made about high practical significance of the developed tool. : The paper covers issues connected to the determination of most preferred values for the parameters of construction processes implemented with application of sliding formwork and defined by the factors of stochastic nature.
