In the attached example of simulation modelling different random numbers have been used and based on the inputs of arrival time and service time tables the statistical results obtained.
The question now is how the system work if we have only 10 customers for the same system but we have a table of random numbers that we should choose from it to construct the model.
The table of random number is set of floating numbers from 1 to 99
i.e.
93.69486
21.97013
54.87906
1.54678
18.07654
86.90543
73.34521
27.6543
98.05432
60.22235
7.9876
.
.
.
and so on
according to these random numbers that we should use, if we want to construct time between arrival determination table, all the time between arrivals (minutes) will be 1 because any random number from the table fall between (001-125)
Is this case acceptable?
If not what we have to do? is there any way to adjust either the range of Random digit assignment or the table??
No, look at table 2.8. the service time varies. So even though the customers arrive uniformly, A waiting list is simulated as you apparently want. Now you can calculate the stats for the system. Best regards, David Booth
The service time varies. so you should look at the digits.
You need to generate random numbers for every parametr and to calculate the main values and it probabilistic distributions. You can even to optimize the structure of your service estation if you calculate in each iteration of your optimization process the simulation of the statistical behavior according the Mount-Carlo's method
