regelsæt

Regelsæt, or rule set in Danish, is a coherent collection of rules that governs behavior, decisions or operations within a defined domain. A regelsæt specifies conditions under which certain actions should be taken, outcomes that should result from those actions, and any constraints or exceptions. It may be formal and machine-readable or informal and human-readable, depending on its purpose and audience.

It is used across fields such as software and data processing, finance, law, governance, gaming, and safety. In software, a regelsæt is processed by a rule engine or a business rules management system to automate decisions. In games and sports, it defines how play proceeds, scoring, and penalties. In regulatory contexts, it codifies obligations, rights and allowed behaviors.

Typical components include a list of rules, each with a condition or trigger and an associated action or conclusion; optional metadata such as priority, scope, version, and provenance; and mechanisms for conflict resolution, defaults, and exceptions.

Developing a regelsæt involves elicitation of requirements, formal modeling, validation and testing, deployment, and ongoing governance. Conflicts between rules are resolved by priorities, specificity, or rule-activation order. Changes are versioned to preserve a history of decisions and ensure traceability.

Examples: a financial rule might state that transactions above a threshold require additional verification; a content moderation rule might block posts containing certain keywords unless overridden by an administrator. In information systems, regelssæt feed into rule engines and business rules management systems (BRMS), and may be represented as decision tables or logical expressions.
