Introduction to Markov Processes in Healthcare Supply Chains
A hands-on workshop on stochastic modelling for logistical systems.
Who is the Course For?
This course is intended for healthcare supply chain researchers, practitioners, and students who want to model uncertainty in logistical systems using Markov Chains. It assumes familiarity with basic probability and matrix manipulation in R.
Learning Objectives
Understand the structure and assumptions of discrete-time Markov chains (DTMCs)
Apply transition matrices to simulate system evolution over time
Compute and interpret steady-state distributions
Model brand switching and service reliability in healthcare supply chains
Simulate and visualize long-run outcomes in R
Link model insights to supply chain policy decisions
Prerequisites
- Comfortable with basic probability (random variables, distributions)
- Familiarity with R and tidyverse for matrix operations and plotting
- No prior knowledge of Markov chains is assumed
