### Department Information and Patient Flow  
Table 3 records all the building-related parameters of the outpatient building of the hospital. There are 14 outpatient departments to be considered and their area requirements are listed in Table 4. The information of 8 fixed facilities is also listed in Table 5. We note that the hospital has the demand of compound departments in practice. That is to say, some departments may be required to be located closely together. In this paper, gynecology and obstetrics must be located on the same floor as the B-Ultrasound room. Additionally, internal medicine and cardiovascular must be located on the same floor, and radiology and the B-ultrasound room must be located in the overlapping area of two adjacent floors.

The patient flow refers to the number of patients moving between two departments. Using a process-mining software DISCO, the patient flows between departments \(c_{ij}\) are obtained from more than 5 million electronic records of patient's treatments in two years, which are presented in Table 6.
