ERROR

Cannot use type {RS} for <p:<!p:int,s:float>,r:string,s:string>. 

please help

Hi

tuple TP
{
  key int p;
  float t;
}
{TP} P = {<1,1.0>,<2,2.10>};;

 

tuple su {
  string r;
  string s;  
}
{su} Route =  {<"A","B">,<"B","C">};

 

tuple RS {
  TP p;
  string r;
  string s;  
}
{RS} RPr = {<pl,r,s> |pl in P, <r,s>  in Route};

 

dvar float RPro[RPr];

subject to
{

forall(RRo in Route){
sum(p in P) RPro[<p,RRo.r,RRo.s>] == 1;
}
}

works fine
