DETECTION OF HARMFUL PROCESS INTENT IN AN INTENT-BASED PRODUCTION PROCESS

Method for detection of harmful process intent in an intent-based production process, comprising the steps:providing (S10) a machine-readable production model (M) linking an intent model (I), correlating to process intent (Ip), comprising production process functions, constraints on measurable properties on the production process functions and/or production process function sequences required for the production process, and a process model (P), correlating to process knowledge comprising a production process behaviour;determining (S20) a safety library (L) of at least one safety process intent (Is), wherein the safety library (L) is protected by security mechanisms to be maintained outside of regular intent-based engineering mechanisms and operation mechanisms;evaluating (S30) changes of process intent (Ip) in view of potentially harmful process intent (Ih) dependent on the at least one safety process intent (Is); andproviding (S40) a report of potentially harmful process intent (Ih) for auditing based on the potentially harmful process intent (Ih).
