Стохастическое моделирование и методы Монте-Карло

The transfer equation with nonstationary function of source is consided. Asymptotical (on time) behaviour of solution of this equation is investigated. The solution is analysed in one point (detector). For that, Monte Carlo methods are constructed on the base of local and double-local estimates. These methods allow to calculate the functionals of the solution and derivatives of these funtionals with respect to time by the same simulated trajectory. The results of comparing of this two methods are presented. Numerical calculations for the semi-infinite medium show that light intensity in detector is equal to exponential function multiplied by weakly decreasing power function. The index of power of this function is obtained by precise calculations.
