In a hospital each surgeon is assigned to a particular operating room (OR) on the same day each week (e.g., Dr. Smith is in OR22 every Wednesday). A surgeon gets exactly one such assignment and each OR gets some use. Other doctors (not surgeons) don't have ORs assigned to them. ORs are described by their (unique) room number and size. Each doctor is described by a (unique) Id, name, and phone
