1.1 Purpose of the model#

Primary purpose

The simulation model provides capacity planning tools for acute stroke and rehabilitation units across a shared service that cares for Stroke, TIA, Complex Neurology and other types of neurological dependency patients. It guides users on the likelihood that a given capacity will cause admission delays.

1.2 Model Outputs#

At the end of a model run the following is calculated:

  • The probability of delay - p(delay) - in admission to an Acute Stroke Unit by bed numbers.

  • The probability of delay - p(delay) - in admission to a Rehabilitation Unit by bed numbers.

  • The reciprocal of p(delay) for both ASU and Rehab. Interpretted as 1 in every n patients is delayed.

  • The occupancy distribution of the Acute Stroke Unit

  • The occupancy distribution of the Rehabilitation Unit

The probability of delay is calculated as follows:

\[P(N = n)/P(N \leq n)\]

1.3 Experimentation aims#

This is an infinite server model. A single scenario is run, given set of arrival and length of stay parameters, to produce a distribution of outputs.
