Solve statement: $148 - Dimension different

GAMS
1

Hi,

my current model contains no visible errors, but my objective variable in the solve statement is flagged as being “referenced with more/less indices as declared” ($148). I have even tried including its domain in the solve statement (“minimizing C(w)” instead of “minimizing C”), but to no avail. I am absolutely clueless as to why this error is occurring and have attached the files in question. As always, any help is highly appreciated.

Best regards,
Hermann

Hi Hermann

You are trying to minimize a multi-valued variable (C(w)). The minimand should be single-valued (e.g. CT =E= sum(w, C(w)); solve yourmodel minimizing CT.

Hope this helps

Dear Renger,

thank you once again for your great help. I promise that next time, I will take a closer look at the documentation before posting here.

Best,
