OK, i changed the code again. Delete the G class (The purpose of G class was to refer to global variables). Add Rnd.seed(12345) in main() function. The new code : http://codeviewer.org/view/code:30da i print the Rnd.expovariate(ArrivalClass.ArvRate). The output i get be executing the above code

Probably a better code : http://codeviewer.org/view/code:30d9 I run the program once using comment in line 39 and then using comment in line 62. The results are not the same. The problem is with the Random. Although, i use seed value equal to 12345, i do not take the same results. :[ Any idea

Sorry, my previous reply was completely wrong. The time is initialized through the initialize() to 0. So, each time i call main() the simulation time is initialized to 0. I changed the code in order to print and check the values of G.Rnd.expovariate(MachineClass.SrvRate) and G.Rnd.expovariate

Thank you @sven ! I thought that the time was reset automatically after calling the second main. Yes, i checked the values and they are the same. -- http://mail.python.org/mailman/listinfo/python-list
