Man-machine interaction model for occupational risk modelling

This paper defines the MORM Model (Man-Machine Occupational Risk modeling) which is devised for modeling risk in wide-scaled industrial systems. We introduce the basic principles of the human-machine interaction model based on a dynamic approach. This approach consists of two features. First, the extended Cognitive Reliability and Error Analysis Method (extended CREAM) and second a high level Petri Net formalism called CO-OPN (Concurrent Object-Oriented Petri Nets) are used for modelling. To illustrate the MORM Model we adapted a case study of a metal wire making process.
