Thank you!
I understand that, and create a variable with the number 1.
The problem occurs at 4965 variable. And this is not the last variable. And
each time is a different number.
while (dateFrom <= dateTo)
{
for (var hour = 0; hour < 24; hour++)
{
var paramDate =
station.Compound.GetParamForDate(dateFrom);
var paramHour = paramDate.ParamByHour(hour);
varCounter++;
paramHour.PriznakDozagruzki = new
PriznakDozagruzki()
{
ParamType = TipDozagruzki.Pmax,
Day = dateFrom,
Hour = hour,
Position = varCounter,
StationID = station.ID
};
taskGLPK.AddVariable(varCounter, lp, GLPK.GLP_BV);
station.FuelInfo.ToList()
.ForEach(p =>
{
varCounter++;
var b = new RashodTopliva()
{
Day = dateFrom,
Hour = hour,
Position = varCounter,
Station = station,
FuelInfo = p,
};
p.RashodTopliva.Add(b);
taskGLPK.AddVariable(varCounter, lp,
GLPK.GLP_CV);
});
}
dateFrom = dateFrom.AddDays(1);
}
public void AddVariable(int varcounter, glp_prob lp, int type)
{
GLPK.glp_add_cols(lp, varcounter);
GLPK.glp_set_col_kind(lp, varcounter, type);
}
