Problem formulation of multi-coordination and multi-synchronisation in CIMS

Two reference models are proposed. The complexity of multicoordinating control in CIMS is due to three main reasons: many types of activities, many aspects to be considered, and management horizons. The first reference model concerns a production activity, expressions such as event, situation, support capacity, load flow and structure between these elements are defined to facilitate the user-problem communication. The second reference model concerns the multicoordinating control structure. Multiaspect and multihorizon attributes and interactivity relationships are defined to formulate multicoordinating control structure and to make it explicit
