getKanban Simulation

This is a Java-based simulation for the getKanban board game. It provides a means by which to test various policies (prioritisation, WIP limits, etc.) without playing the game.

Configuring

Most decisions are captured by policies. For example:

• Which cards to expedite
• How to assign dice to cards
• The order in which to pull cards from the backlog
• Optional events (such as sending Ted on training)

The BoardRunner class is the starting point for changing policies.

Building

mvn clean package

This will produce an executable JAR with all the dependencies included.

Running

• mvn exec:java; or
• java -jar target/get-kanban-simulation-<version>-jar-with-dependencies.jar

Using the java -jar method allows you to provide the number of trials as a command-line argument, such as:

# 10,000 trials
java -jar target/get-kanban-simulation-<version>-jar-with-dependencies.jar 10000

Running the project shows four percentiles (50, 70, 85, 95) of the distribution of financial summaries associated with the trials.
