Emergency

We simulate the behavior of an Emergency department in an hospital.

The department in organized in two sections

• A single Triage, where patients are received, quickly examined, and assigned a severity code
• A number NS of doctor studios, that operate in parallel. Each doctor will receive the next patient, act on him, and then release him

The severity code gives priority in accessing the doctors. Patients with the same severity will be called in arrival order.

Severity Codes

• WHITE: not urgent, may wait without problems.
  • After WHITE_TIMEOUT, if not served, goes home
• YELLOW: serious but not urgent
  • After YELLOW_TIMEOUT, if not served, becomes RED
• RED: serious and urgent, risking life, must be served as soon as possible
  • After RED_TIMEOUT, if not served, becomes BLACK
• BLACK: dead. No need to be served.

Timing

Phase	Required Time	Example
Triage	DURATION_TRIAGE	5 minutes
Handling a White patient	DURATION_TRIAGE	5 minutes
Handling a Yellow patient	DURATION_TRIAGE	10 minutes
Handling a Red patient	DURATION_TRIAGE	15 minutes
Handling a Black patient	N/A	not needed

Simulation Parameters

Inputs

• Parameter: NS
• Initial events:
  • NP patients
  • arriving every T_ARRIVAL minutes
  • with a round-robin severity (white/yellow/red/white/…)
• Simulate from 8:00 to 20:00

Outputs

• Number of patients dismissed
• Number of patients that abandoned
