Decision Support in Production Planning of Precast Concrete Slabs Based on Simulation and Learning from Examples

Simulation is one of methods enabling support of the planning of construction processes. The article presents the possibilities of using simulation as a component of a hybrid advisory system. The system is based on the accumulation of knowledge from observations and using it with previous cases as an analogy and likeness of cyclic processes. Simulation is used to verify hypotheses in the selection of resources and parameters of the process. The study explores available simulation software (MicroCyclone, FlexSim, and AnyLogic) and compares them in terms of ease of implementation, data readability and quality of results. Created statement is used for selection of software, which reflects the actual model of building processes with the highest precision.The problem of production of precast slabs was analyzed. On the basis of research to determine the duration of individual tasks of production, simulation model was defined. Using available software (MicroCyclone, FlexSim) capable of simulating the production process, changes in the selection of the composition of the team and materials have been proposed, enabling improvement of the efficiency of prestresed core slabs production on the analyzed line in the prefabrication plant.
