hello,

i'm a new user of opl studio. I have a problem. i don't know how to calculate a value of a variable in opl script. i need to calculate it into the minimize problem (on-line). i want know if it's possible

Hello biaigo,

Here is an example that initializes data in two ways - with an OPL statement (started) and with script (now and startTime).
Hope this helps,

Didier.

using CP;     range tasks = 0..10; dvar interval myIntervals[tasks] size 4;   
// Example of data initialization with an OPL statement - random value between 0 and 1 

int started[t in tasks] = rand(2);   

int startTime[tasks]; 

int now; 
// Example of initialization of a variable in script execute 
{ var current = 0; var t; 

for (t = 0; t<= 10; t++) 

if (started[t] == 1) 
{ startTime[t] = current; current += 5; 
} 

else started[t] = -1; now = current; 
}   minimize max(t in tasks) endOf(myIntervals[t]); constraints 
{ forall(t in tasks : started[t] == 1) startOf(myIntervals[t]) == startTime[t]; noOverlap(myIntervals); 
}
