### adding more constraint to gams

Posted:

**Wed Feb 12, 2020 4:12 am**Hi,

I look into adding some additional bounds/constraints to following MODEL (program is part of simple moral hazard situation :idea:3 equations,3 variables-

(i)U

(ii &iii) w(x) is variable while argument x takes 2 values-High Investment,Low investment) ;

r(x) has fixed value)[/code]

r(x) & w(x) are related as below;

How I can put this in my program.

I can send full program if required.

THANX IN ADVANCE

(ii &iii) w(x) is variable while argument x takes 2 values-High Investment,Low investment) ;

Code: Select all

```
[code]obj.. U =e= sum((x,y), dummy(y)*p(x,y)*(r(x) - w(x)));
pc(y).. (sum(x,p(x,y)*sqrt(w(x)))-d(y))*dummy(y) =g= 0;
ic(v,y).. ((sum(x,p(x,v)*sqrt(w(x)))-d(v))
-(sum(x,p(x,y)*sqrt(w(x)))-d(y)))*dummy(v) =g= 0;
```

r(x) & w(x) are related as below;

**1.3w(x) < r(x) < 1.6 w(x)**How I can put this in my program.

THANX IN ADVANCE

*(please neglect any numerical twists due to present fixed numbers-I am looking for how to capture bound/constraint into Model where argument is a set)*ABRAHAM
