Abstract :
This work presents an investigation of uncertainty calculations in TLM simulations. The technique consists in expressing the problem using recursive Taylor series expansions. The use of recursive Taylor expressions allows the exact calculation of the time evolution of the expected value and the variance of each random variable of the problem. In comparison to Monte Carlo methods, the present approach is significantly faster.
