Hi, I’m new to GAMS and stumbled upon a problem that I couldnt fix by

searching google or this groups’ discussions…

I am trying to create a simple model with random numbers for demand of

different products in several periods. For example, for product 1,

GAMS should generate different random numbers based on a uniform

distribution with lower bound = 10, upper bound =50 for each period t.

I thought it might look similar to this:

Sets

i set of products /1*3/
t set of time periods /1*10/;

table d(i,t) demand of product i in period t

1*10

1 uniform(10,50)

2 uniform(3, 25)

3 normal(35, 10) ;

…

But I get an error message because GAMS expects real numbers in the

table. How can I resolve this error?

Any help would be very much appreciated.

Peter
