Algorithm 1 Simulating patient-to-nurse assignment based on acuity levels
1:	Find the first available nurse (nurse assigned to patient agents with a total acuity level less than the maximum acuity level of the nurse, $L{P}_u$);
2:	Check if the to-be-assigned patient agent has an acuity level, $L{P}_i$, less than or equal to the access acuity level that the nurse can handle;
3:	If step 2 is true, assign the patient agent to the available nurse directly before the premedication stage;
4:	Increase the number of assigned patient agents to the nurse, $L{A}_u$, by the value equal to the acuity level, $L{P}_i$, of the last assigned patient agent;
5:	After patient agent discharge, decrease the number of assigned patient agents to the nurse by the value equal to the acuity level, $L{P}_i$, of the discharged patient agent;
6:	Repeat step 1 to 5 for all patient agents
