Project Structure

JAS-mine separates model behaviour, output collection and graphical observation into managers. SimPaths applies that pattern within its Maven project.

Role	SimPaths implementation
Model	SimPathsModel creates the simulation state and schedules processes on Person, BenefitUnit and Household.
Collector	SimPathsCollector computes and exports statistics and selected entity records.
Observer	SimPathsObserver supplies charts and monitoring in interactive runs.
Experiment builder	SimPathsStart or SimPathsMultiRun constructs and registers the managers.

Where to work

Source is under src/main/java/simpaths/. The model/ package contains agents and model processes, data/ contains loaders and supporting calculations, and experiment/ contains execution, collection and observation.

input/ holds parameters and simulation inputs; config/ holds run configurations; output/ holds run results. Maven generates compiled files under target/. The root pom.xml specifies dependencies and builds the single-run and multi-run executables.

The Repository Guide is the canonical directory and data-pipeline reference. An Eclipse-generated JAS-mine demo structure is not required to work on SimPaths.

Follow the lifecycle

Manager objects are registered with the engine before execution. Their buildObjects() methods prepare state; their buildSchedule() methods register events. Collector and observer schedules are separate from the model schedule, so their timing determines which state is recorded or shown.

See The Model and the Schedule for event ordering, Start Class Implementation for startup and Statistical display for output controls.
