Error

Expecting a component in tuple <p:<!p:int,s:float>,r:string,s:string>, found pl.   

please help

Hi,

{string} R={"A","B"};
  {string} SUPP={"A","B"};
 
  tuple TP
{
  key int p;
  float t;
}
{TP} P = {<1,1.0>,<2,2.10>};;

 

tuple su {
  string r;
  string s;  
}
{su} RawRoute =  {<"A","B">,<"B","A">};
 
 tuple RS {
   TP p;
   string r;
   string s;
}
{RS} Pr = {<pl,r,s> |pl in P, <r,s>  in RawRoute};

tuple PS{
  TP p;
  string s;
}
{PS} PrS = {<pl,s>|pl in P,s in SUPP};    //   SUPP are strings

int RP[R]=[1,2];

dvar float nR[PrS ];

subject to
{

forall(RRo in Pr){
nR[<RRo.p,RRo.s>] == minl(1,sum(r in R)RP[r]);  // R are strings
}
}

works fine

Thanks for your valuable reply

but my RP is a decision variable

dvar float RP[Pr];

dvar float nR[PrS ];

forall(RRo in Pr){
nR[<RRo.pl,RRo.s>] == minl(1,sum(r in R)RP[RRo]); 

so we can't use RP[r] it should be RP[Pr] but since i am adding r so how can i do it?

please help

subject to

forall(RRo in Pr){
nR[<RRo.p,RRo.s>] == minl(1,sum(r in R)RP[r]);  // R are strings
}
}

works too
