Planuns

Planuns are a theoretical construct in planning theory that refers to modular, autonomous units that cooperate to generate and execute plans in distributed environments. The term combines planning and units to emphasize modularity and local autonomy within a shared objective. In the standard conception, each Planun maintains a local model of its environment, a repository of objectives, and a set of action policies. Planuns coordinate through lightweight communication protocols to align actions without centralized control.

Historically, Planuns emerged from studies of multi-agent systems and distributed optimization, where centralized planning proved brittle in dynamic settings. Proponents argue that Planuns can provide resilience through redundancy and faster response to local changes. Critics point to coordination overhead and potential inconsistencies between Planuns.

Applications span supply chain networks, smart cities, disaster response simulations, and modular software orchestration. In practice, Planuns are simulated in agent-based models and used as a design metaphor rather than a turnkey technology.

Limitations include the need for robust communication channels, risk of strategy divergence, and vulnerability to adversarial interference. Research continues into governance mechanisms, convergence guarantees, and privacy-preserving coordination.
