我是 GNU GLPK 的新用户，我正面临这种类型的错误。你能帮忙解决吗？错误信息：
Generating EQ_SpecifiedDemand...
OSeMOSYS_test1-22.txt:193: SpecifiedAnnualDemand[TUNISIA,ELEC,2010] out of domain MathProg model processing error
这是我的参数：
param SpecifiedAnnualDemand{y in YEAR,f in FUEL,r in REGION};
param SpecifiedDemandProfile{y in YEAR, l in TIMESLICE, f in FUEL, r in REGION};
param YearSplit{y in YEAR,l in TIMESLICE};
s.t. EQ_SpecifiedDemand{r in REGION, l in TIMESLICE, f in FUEL, y in YEAR}:
SpecifiedAnnualDemand[r,f,y]*SpecifiedDemandProfile[r,f,l,y] /
YearSplit[l,y]=RateOfDemand[r,l,f,y];
任何线索？
