Regelmenge

Regelmenge, literally “set of rules,” is a German term used in technical literature to denote a curated collection of rules, constraints, or procedures that govern the behavior of a system, model, or process. It is commonly used in control theory, computer science, and linguistics to distinguish rule-based specifications from other modeling components such as objectives or data-driven elements.

In control engineering and process automation, the Regelmenge defines the logic that translates sensor inputs into actuator commands, often incorporating safety constraints, limits, and mode-dependent behavior. It may be fixed or subject to adaptation, and is analyzed for properties such as completeness, consistency, and robustness.

In artificial intelligence and expert systems, the Regelmenge corresponds to a production-rule base, typically expressed as if-then rules. An inference engine applies these rules to derive conclusions or actions. Key design considerations include rule coverage, non-contradiction, and conflict resolution.

In linguistics and formal grammars, the term can refer to the production rules of a grammar that determine which strings belong to the language. The Regelmenge defines allowable constructions and transformations within the formal system.

In modeling and systems engineering, the Regelmenge is often complemented by optimization or learning components to improve decision-making or adapt to changing conditions. The concept emphasizes clarity, verifiability, and modularity, enabling engineers and researchers to examine and modify the rule set independently of data or objectives.
