Analysis Of The Multiphase Queuing System (A Case Study Of The Federal Medical Centre, Umuahia):- Mmahi, Ekenma C.

ABSTRACT

 This study aims at reducing the waiting time of patients at the antenatal care unit of the Federal Medical Centre Umuahia, as well as optimizing resource utilization. Based on the observations made at the case unit, a single server single queue system with multiple phases is typical of its operations. This study has employed the observation method to keep log of arrival and departure time of patients. From the data collected, arrival and service rates were obtained. These performance parameters were analyzed for the model in existence and experimented on other multiphase queuing models to obtain the optimal model for the system. Results indicate that the multi server queuing system with multiple phases (Erlang model II) has a waiting time of 0.15 minutes, and a server utilization of 46% .This result supersedes that ofthe other queuing models given that it contributed the least total cost to the system. The Erlang service time model II has been adjudged to be optimal for the system in terms of waiting time and utilization.
