[Example of Monte Carlo Simulation Tool]

A part of our data analysis services, we offer a service to create a probabilistic decision making programs. We build progrmas that can make decisions about how the probability of damage will grow as a given structure exposed to various environments. The safety of all structure can not be determined deterministically. The probability of the failure changes moment by moment.

BRSystems service involves the construction of a program to calculate of the probability of the damage to an object on the external and internal environment exposed. The program requires data on the structure of the object, the relationship between the fracture of the metal and the stress (j-integral) generated under the expected environment, the specific load of the external and internal environment, and so on.

Since the safety probability of a structure is determined based on the all factors involved, sensitivity analysis helps to elucidate the weakness of the structure.
