Intelligent Systems Configuration Services for Flexible Dynamic Global Production Networks

FLEXINET

FP7 project 608627 – now in negotiation

The FLEXINET Concept

Basic premise - reference ontologies• Any multi-system design or configuration method needs a

common base of concepts from which to build and to share knowledge

• Text based concepts are not good enough – see next slide• Formal languages like OWL are NOT sufficiently

expressive to represent the complexities of manufacturing

• Common Logic based formalisms provide both a semantic capability and also an inference capability for compliance checking

Problem – multiple standards with multiple text based semantics

•Resource (ISO 15531-1; ISO 18629-1): Any device, tool and means, except raw material and final product components, at the disposal of the enterprise to produce goods or services. This definition includes ISO 10303-49 definition.

•Resource (ISO 10303-49): Something that may be described in terms of a behavior, a capability, or a performance measure that is pertinent to the process.

•Resource (ISO 15704): An enterprise entity that provides some or all of the capabilities required by the execution of an enterprise activity and/or business process.

Are these definitions the same or different? How similar are they? Do they provide any basis across which sharing can be achieved? It is not possible to say definitively

Formal definitions using a Common Logic base

(=> (Core.Resource ?r) (exists (?c) (and (Core.Capability ?c) (Core.hasCapability ?r ?c)))):IC soft "Every resource may have some capability." (=> (Core.Resource ?r) (exists (?e) (and (Core.Enterprise ?e) (Core.isHeldBy ?r ?e)))):IC soft "Every resource may be held by some enterprise." (=> (Core.Resource ?r) (exists (?p) (and (Core.Process ?p) (Core.isUsedBy ?r ?p)))):IC soft "Every resource may be used by some process."

•Cannot be misinterpreted

•Can be used to build new ‘specialisations’ to suit specific requirements

•Inferences can me made based on the logic
