Getting started with simmer for patient flow modeling
Trying to do DES in R

simulation
patient flow
library(simmer)In an earlier post, Getting started with SimPy for patient flow modeling, I developed three very simple patient flow models as part of my learning SimPy process. Now I’ll build those same simple models using simmer. See the earlier post for details about the system being modeled. In a nutshell, it’s an inpatient obstetrical setting in which patients flow through three units: OBS -> LDR -> PP in the process of giving birth. Arrivals are Poisson and all length of stay distributions are exponential. My goal is to start to learn how to use simmer for discrete event simulation and do some comparisons with SimPy.
obflow_1 - Stays modeled with delays (no resources)
Same scenario as in the SimPy version.
- Exponential arrivals
- Stays modeled as delays (no resources)
Define a few constants.
ARR_RATE <- 0.4
MEAN_LOS_OBS <- 3
MEAN_LOS_LDR <- 12
MEAN_LOS_PP <- 48
RNG_SEED <- 6353Create a simulation environment. This is similar to env = simpy.Environment() in SimPy.
env1 <- simmer("obflow_1")
env1## simmer environment: obflow_1 | now: 0 | next:# Initialize random number generator
set.seed(RNG_SEED)Create a trajectory to model the patient flow logic. Simmer is very process oriented. A trajectory contains a chained sequence of simmer statements for doing things like seizing and releasing resources, setting entity attributes, print log statements, and a number of other activities. See the Add Activities section of the Reference manual.
Note the use of the magrittr pipe operator (the %>%) to chain the statements together.

When a patient tries to move on to the next unit in their trajectory, they may get blocked in their current unit if there are no beds available. So, we need to make sure that bed release isn’t done until next destination is seized.

The trajectory concept is intuitively appealing and simmer does have quite a few activities that can be added to them for more complex modeling needs (renege, select from a resource pool, branching, rollback, and quite a few more.) I did find myself longing for the flexibility and elegance of Python and felt that the chaining of activities for complex processes was going to end up being difficult to create, maintain, and most of all, debug. Then again, this may be due to the fact that while I’ve used both R and Python extensively, I tend to use Python for more “programmatic” things and R for statistical analysis and modeling. Perhaps if I was a better R programmer, simmer would be more appealing to me. I’ll continue to tinker and explore simmer but I’m thinking I’m going with SimPy for now for my open source DES work.
Before leaving simmer, I created one more model in which I use its branch activity to model a proportion of patients requiring a c-section and then a longer length of stay in postpartum. This also gave me a chance to try out some of simmer’s monitoring and plotting (via simmer.plot package). Nice.
