If you’re new to PDQ, here’s a simple queueing model written R that you can paste directly into an RStudio console or script window:
# A simple M/M/1 queueing model in R-PDQ.
require(pdq)
# input parameters
arrivalRate <- 0.75
serviceRate <- 1.0
## Build and solve the PDQ model
Init("Single queue model") # Initialize PDQ
CreateOpen("Work", arrivalRate) # Create workload
CreateNode("Server", CEN, FCFS) # Def single server
SetDemand("Server", "Work", 1/serviceRate) # Def service time
Solve(CANON) # Solve the model
Report() # Formatted output
