In any country healthcare service takes a
major place which provides care for persons who are not
well. When considering the Healthcare service in Sri
Lanka, National Hospital of Sri Lanka plays a major role.
The hospital faces the problem of overcrowding the
patients and long waiting queues of patients for different
healthcare needs specially on surgical purposes. The
objective of the study is to introduce a queuing model for
optimizing the performance of surgical units in National
Hospital of Sri Lanka. In the study, the operation theaters
of Accident and Emergency unit were only considered.
According to the queuing model M/M/3 the existing
system is not utilized well due to arrival rate is higher
than the service rate. Hence it is needed to increase the
service rate. According to the current system the theaters
function in 4 equal work shifts in 24 hours. Some
operation theaters do not function on all the shifts. It was
identify that the average maximum service rate of one
shift is 4.25 patients. By making all theaters functioning
in that rate in all shifts the system can make efficient with
the service rate of 51 patients per day. This task will be
achieved by increasing the capacity of live resources.
