In Figure A.6 we define the three types of patient entities that will flow through
our business model. Since the patient types, levels 1, 2, and 3, arrive at the hos-

the patient entity types. By choosing the level 1 schedule in the Figure A.6 dialog
and the edit function, we can now describe the interarrival schedule for the level 1
patients, a
