[R] binary goal programming in R

[Jürg Altwegg]

Dear R-help members

I would like to use the R package goalprog, weighted and lexicographical goal programming and optimization to optimize a location problem.

In my model I need a "yes" or "no" decision - in this case, whether to select a site or not - are represented by 1 and 0.

Does somebody has experience with this problem and know how this could be done?

Thanks for your help in andvance.

Best wishes Jürg Altwegg
