Optimizing an AltaRica simulator

Since the AltaRica language has, in fact, become the European industry standard, the AltaRica-based simulation method is one of the important research contents in the field of safety analysis methods. At the same time, in practical applications, simulations are mostly executed tens of thousands of times. Therefore, it is practical to optimize the execution time of the simulation method. We first analyze the hotspots in the execution of simulation methods and then propose two optimization strategies for two hot issues. The optimization method is designed and implemented by the method of space for time. Finally, the effectiveness and application scenarios of the optimization method are illustrated by experiments with different scale models. Moreover, the experiment data shows that the optimization method is effective in most cases.
