How to assign process time and standard deviation through global Table?

Hi,


I want to specify the average processing time and standard deviation of the machine through the Global Table. The standard deviation is multiplied by a global variable, and the processing time is normally distributed. I have tried the below method but it doesn't work.


Thank you for your advance. :)

your deviation value is too large. The function may return negative values!

"it doesn't work." Can you be a bit more specific? Are you getting errors? Are the values not what you expect?

statDistribution_by_lookup_table_values.fsm

Model file is Flexsim 18.2.3 and works as expected:

normal(Table("bbb")[1][5],(Table("bbb")[1][6]*bbbb),getstream(current))
