model

[Hugo Caçote]

Hi,

 

I have model where i want of force that the solution variable x (j) is more than 2. How can I do this without having to specify an equation forcing the variable to be more than 2 for each j ? Currently I only have 4 j indexes but in case I increase my model I do not want to write an equation for each.

 

 

Currently I have the following modeled:

 

table d(j,k) "annual demand for j, intermediate k"
  0       1        2
1 4645    5014     8397
2 13631   19734    18219
3 10163   19667    5818
4 22168   6229     1182 ;

 

positive variable x(j) "number of campaign of j"; 

...

 

risk1..
d('1','2')/ x('1')
=g=2 ;

risk2..
d('2','2')/x('2')
=g=2 ;

risk3..
d('3','2')/ x('3')
=g=2;

risk4..
d('4','2')/ x('4')
=g=2;

 

Thank you, Cheers,

Hugo

You must set the lowerbound of the variable to the desired value

  x.lo(j) = 2;
