A PETRI NET MODEL OF A HOSPITAL OPD

Abstract

In Hospitals, managing patient flow in OPD is crucial to minimize waiting time, en- suring optimal resource utilization, and improving patient satisfaction. In this paper, a Petri net model for hospital OPD has been constructed and used to solve the problem of queuing for too long. Petri net allows for detailed visualization due to its graphical representation. Petri nets are applied to model the movement of patients through various stages of OPD, such as registration, consultation, diagnostic tests, and discharge. Furthermore, its boundedness, liveness, and deadlock are discussed in detail. To reduce waiting time, online registration through an app/website to avoid standing in a queue for a long time has been introduced.
