description: Master thesis topic: sliding formwork technological parameters optimization with mathematical model and its 4D project model collaboration.
Tasks of the work are following: 
ï­ Describe in stages the main technological processes and parameters that affect the speed and quality of the erection of vertical structures in sliding formwork
ï­ Create an analytical model of the vertical structure slipforming construction.
ï­ To determine a method for optimizing the design parameters of sliding formwork technology using the obtained stochastic mathematical model
ï­ Develop an approach to the interaction of the developed analytical model of the technological process with the 4D model of the project
ï­ Justify the application of the obtained dependence and approach to the project of erecting a monolithic structure in a sliding formwork.
It is shown that studies related to sliding formwork, as well as the use of BIM technologies for formwork, do not consider the possibility of simultaneous optimization of individual technological parameters in the conditions of shortened construction periods.
A mathematical stochastic model of the process of erecting a vertical structure in a sliding formwork is proposed. It selects independent technological characteristics of the process for its reduced duration. A technique for the interaction of the 4D model and the created mathematical model is proposed. It supposed to use a mathematical model to optimize the technological parameters of an individual process and record the changes in the 4D environment.
The proposed model and its integration system with the 4D model of the project were tested on the Artic LNG2 project, in which a large amount of work in sliding formwork is carried out for a limited time. The technological parameters which allows to finish wall construction at time with minimum cost are determined. The probabilities of the occurrence of the limiting conditions of the model for each alternative variant of technological parameters are obtained. The cycle of interaction of the 4D model of the project and the mathematical model of the process, which was tested for the project, made it possible to build the structure in a shorter time.
