OPL CPLEX语法问题与元组数组

这是.mod（模型文件）

tuple TDayPair{
  string day1;
  string day2;
}

{TDayPair} DAYS={<"Mon","Tue">,<"Thurs","Fri">};
int a[DAYS]= ...;
execute {
  writeln(a[<"Mon","Tue">]); //<--it gives syntax error here
}

这是.dat（数据文件）

a = #[
  <"Mon","Tue">:1,
  <"Thurs","Fri">:2,
]#;

，它在writeln（a [＆lt;“ mon”，“ tue”，“ tue”＆gt;]）;>>> >>这里有什么问题？

原文

This is .mod (model file)

tuple TDayPair{
  string day1;
  string day2;
}

{TDayPair} DAYS={<"Mon","Tue">,<"Thurs","Fri">};
int a[DAYS]= ...;
execute {
  writeln(a[<"Mon","Tue">]); //<--it gives syntax error here
}

This is .dat (data file)

a = #[
  <"Mon","Tue">:1,
  <"Thurs","Fri">:2,
]#;

It gives syntax error at the model file at writeln(a[<"Mon","Tue">]); what's the issue here?

如果您写的话，

tuple TDayPair{
  string day1;
  string day2;
}

{TDayPair} DAYS={<"Mon","Tue">,<"Thurs","Fri">};
int a[DAYS]= ...;
execute {
  writeln(a[DAYS.find("Mon","Tue")]); //<--it gives syntax error here
}

您将获得

OPL建模语言与 OPL JavaScript语言有助于预处理，后处理和流控制。

If you write

tuple TDayPair{
  string day1;
  string day2;
}

{TDayPair} DAYS={<"Mon","Tue">,<"Thurs","Fri">};
int a[DAYS]= ...;
execute {
  writeln(a[DAYS.find("Mon","Tue")]); //<--it gives syntax error here
}

You will get

OPL Modeling language is not the same as the OPL Javascript language that helps with preprocessing, postprocessing and flow control.
