calc_queue_load: Calculate Queue Load

In NHSRwaitinglist: Waiting List Metrics Using Queuing Theory

Calculate Queue Load

Description

Calculates the queue load. The queue load is the number of arrivals that occur for every patient leaving the queue (given that the waiting list did not empty). It could also be described as the rate of service at the queue. The queue load is calculated by dividing the demand by the capacity: queue_load = demand / capacity.

Usage

calc_queue_load(demand, capacity)

Arguments

demand	Numeric value of rate of demand in same units as target wait - e.g. if target wait is weeks, then demand in units of patients/week.
capacity	Numeric value of the number of patients that can be served (removals) from the waiting list each week.

Value

Numeric value of load which is the ratio between demand and capacity.

Examples

# If 30 patients are added to the waiting list each week (demand) and 27
# removed (capacity) this results in a queue load of 1.11 (30/27).
calc_queue_load(30, 27)
