BEDS is built on the assumption that patients arrive with a stationary intensity, and that the distribution governing their length-of-stay is also stationary. Thus, BEDS works only when modeling inpatient wards.
BEDS further assumes a setup consisting of a number of patient types and wards. The wards contain a fixed capacity. Patient...
