The thesis focuses on achieving a significant speed-up in the estimation of simulation model parameter values. This is achieved through the appropriate choice of a solver that is computationally less demanding, but at the same time has an acceptable error in the range of parameter values, through the use of distribution of computations on parallel threads, heuristic methods for reducing the space of parameter values, and modification of optimization methods. In this thesis, the research related to the objectives of the thesis is first discussed, then the exact objectives of this thesis are stated and the implementation of each objective is described in separate chapters. The results of this thesis include a tool used to analyze solver choice, an analysis of parallel thread efficiency, a parallel simulation distribution tool, nine modified optimization methods, and a new tool for estimating parameter values. Finally, the results obtained are evaluated.
