projectcyclus

ProjectCyclus is an open-source software framework designed to model and simulate cyclical processes across domains where resources, flows, and timescales interact. Its design emphasizes modularity, reproducibility, and scalability, enabling users to assemble custom simulations from a core engine plus domain-specific plug-ins.

Developed by a distributed community of researchers and practitioners, ProjectCyclus provides a core simulation kernel, a component catalog, and tooling for scenario creation and analysis. The architecture is plug-in based, allowing researchers to implement new process types, data models, and objective functions without modifying the engine. It supports batch simulations, parameter sweeps, and comparative analysis across scenarios, and is accompanied by documentation, tutorials, example models, and a language-agnostic API.

Development is community-governed, with public repositories, contribution guidelines, and issue tracking. Releases are distributed under an open-source license to encourage collaboration and transparency. The project emphasizes reproducibility through versioned scenarios, input data, and provenance tracking of results.

Typical applications include studying resource cycles, industrial processes, logistics networks, and energy systems where cyclical behavior and feedback dominate outcomes. Users range from university researchers to policy analysts and engineering teams seeking transparent modeling tools.
