Monitoring An Operability Of A Production System

An apparatus for monitoring operability of a production system, the apparatus comprising:

• an input unit to input production-related data of the production system;
• a mapping engine to map the production-related data to instance data of a first knowledge graph according to a given mapping definition;
• a first validation unit to validate a consistency and/or an integrity of the instance data using declarative constraints and to output a first validation result;
• a simulator to generate a computer-implemented material flow simulation model of the production system based on the instance data and depending on the first validation result;
• a generator to generate simulated production logs using the material flow simulation model;
• a second validation unit to validate the simulated production logs against measured production logs of the production system and to output a second validation result;
• and
• an output unit to output the second validation result for monitoring the operability of the production systems.
