}

}

and getting

E = [16,3,5,7,98,1,5,411,5,68];

now with the help of E i want to create ranges

range K = 1..E[C][D]

showing error K is not in opl project

Actually i want to make range

range K = [1..E(1),

                  1..E(2),

                  1.E(3),

                   .

                   .

                   .];

Hi,

do you want K to be a range or an array of range ?

regards

K to be range

when C= 1, D = 1

range K = 1..E(1);

when C = 1,D = 2

range K = 1..E(2);

.

.

This way it change in a loop

Hi,

what about something like

range C = 1..100;

range D = 1..60;

int E[c in C][d in D]=c*45+d;

int KMin[c in C][d in D]=1;
int KMax[c in C][d in D]=E[c][d];

execute
{
writeln(KMin,KMax);
}

?

regards

Hi,

but in OPL you cannot have array of ranges so that is why I suggested 2 arrays with the lower and upper bounds.

Or you may try arrays of sets like:

range C = 1..10;

range D = 1..60;

int E[c in C][d in D]=c*45+d;

int KMin[c in C][d in D]=1;
int KMax[c in C][d in D]=E[c][d];

{int} K[c in C][d in D]=asSet(KMin[c][d]..KMax[c][d]);

execute
{
writeln(KMin,KMax,K);
}

regards

This error occurring :

range D = 1..60    

int E[c in C][d in D] = opl.floor(1000/[c]);
      

ERROR ::     

syntax error, unexpected '(', expecting ';'   ( in opl.floor(1000/[c]);)

please help

It seems that E needs to be float instead of int:

float E[c in C][d in D] = floor(1000/c);

Also, I used only floor without Opl.floor

if i am using float then

range C = 1..10;

range D = 1..60;

float E[c in C][d in D]=floor (1000/c);

float KMin[c in C][d in D]=1;
float KMax[c in C][d in D]=E[c][d];

{float} K[c in C][d in D]=asSet(KMin[c][d]..KMax[c][d]);

execute
{
writeln(KMin,KMax,K);
}

error THE FUNCTION asSet (range float) does not exist

Use ftoi then:

range C = 1..10;
range D = 1..60;
float E[c in C][d in D]=floor (1000/c);
int KMin[c in C][d in D]=1;
int KMax[c in C][d in D]=ftoi(E[c][d]);
{int} K[c in C][d in D]=asSet(KMin[c][d]..KMax[c][d]);

How can i convert int to float means opposite of "ftoi"
