I have a parameter with 4 dimensions which I would like to import in Excel.
Currently I have a series of Excel sheets with each over 500,000 rows. The columns are:
- Parcel,
- Farm,
- Year,
- Species,
- Class,
- Surface
Ideally I would like to have a parameter in GAMS like: Surface(Parcel,Farm,Year,Species,Class)
Is there an elegant way to do this?
