Every year the individual assignment for the Systems Modelling and Simulation module has a different theme.

For example, in the previous years the assignments had manufacturing, banking services, airports, and

logistics themes. This year our assignment is about Healthcare. All this variation allows you to appreciate

how this fundamental subject can be applied to different problems which fundamentally have similar

performance indicators. Enjoy this year$$s assignment!

A clinical centre in a war torn country in a remote area receives patients with various conditions. The clinic

works $24$ hours a day and admits two types of patients.

Patient Type $1($Low Priority$)$: These are type of patients that are of low priority and they are normally treated

by either the Clinical Nurses $($CN$)$ or the General Practitioners $($GP$).$ These patients arrive at the hospital with

a rate Expo $(20)$ min. They are seen by the admission officer, register and are sent to the Triage station. The

registration follows POIS distribution with the following parameter $(8)$ minutes. At the Triage station if a CN is

available they are assigned to a nurse and only at special occasions if all the CNs are busy and if a GP is

available the patient will be seen by the GP for assessment. If there are no Triage staffs available, the patients

wait in the waiting area. This area has maximum capacity of $20$ people $($i$.$e$.$ if the number in the queue behind

the Triage is more than $20$ the patient leaves the hospital$).$ Report on the record of number of patients who

leave the medical centre without being attended to$.$ Patients that arrive during the break of the Admissions

officer leave the system $($record the number and report on this number of patients leaving due to admissions

being closed$)$

The Triage processes consist of Patient Assessment, the assessment process follows a Triangular

distribution with the following parameters $(8,12,15)$ minutes. After the assessment process $85\%$ of the

patients are diagnosed, given medication by the Triage staff and leave the clinic. The remaining $15\%$ have

further complications that require further consultation with a GP in the Triage for further assessment. The

processing time for these patients is Uniform $(7,10)$ minutes. $30\%$ of these patients who have been

diagnosed by the GPs need to be admitted to a bed for admission of drip medicine or monitoring and the rest

of patients are discharged and leave the system. The admitted patients normally occupy the beds following

a Triangular Distribution $(10,20,35)$ hours.

All discharge processes require the chief nurse and one of the GPs $($the less busy one$)$ to assess the patient.

This process takes a Weibull distribution $(14,18)$ minutes. The patient is provided with the necessary

medication and leaves the system
