We should also open tickets:

• to add an example notebook demonstrating this new functionality
• adding any references to formulations @rongboxu used (if not already in the docs)
• anything else?

To be clear, these things are not critical to be part of this PR.

• About 2, yes, I need to add one preference, which is the book, business site selection, location analysis and GIS.

I thought we had already had that one in our References, but it looks we had missed it. So nice catch. A bibtex entry will need to be added to references.bib
