Could you please help me, how to set time limit to slove this problem.

Moreover, I want to have:

timelimit =10 seconds

if timeslove > 10 then:

     Intime = 1

     return the solution if it has

Else   

     Intime = 0

     return the solution

Thanks in advance for your help

This is my code:

/*********************************************

using CPLEX;
// Number of Jobs
int nbJobs = ...;
int LmaxStar = ...;
range Process = 1..nbJobs;
int p     [Process] = ...;
int d     [Process] = ...;
int w     [Process] = ...;
dvar int P     [Process];
dvar boolean x[Process][Process];
dvar int+ h;
minimize h;
subject to
{    
    forall(k in Process)
      sum(j in Process) x[j][k] == 1;                           
    forall(j in Process)
      sum(k in Process) x[j][k] == 1;                          
    forall (k in Process)
        sum(j in Process,l in 1..k ) (p[j] * x[j][l])- sum(j in Process)(d[j]*x[j][k]) <= LmaxStar;
     forall(j in Process)
      P[j] == sum(k in Process) k * x[j][k];
    sum(j in Process) w[j] * P[j] == h;
}
execute
{
    cplex.tilim = 10; / / >>>>>> it not work
    var f=new IloOplOutputFile("A.txt");
    f.write(h + "      ");
    for(var j=1; j <= nbJobs; j++)
        for(var k=1; k <= nbJobs; k++)
        {    if (x[j][k] > 0)
                f.write(x[j][k]*k+" ")
        }
    f.close();

Hi

execute
{
    cplex.tilim = 10;

)

should be before the subject to block
