3. Problem statement
• Diagnosis and treatment
• EHR, CT scans, Domain knowledge,..
• Manufacturing of customized products
• Key issues
• Degree of customization
• Delivery time
• Barriers to customization
• lack of efficiency of traditional manufacturing enterprise to
handle low-series or one-of-a-kind production tasks
• lack of efficiency in transfer of multi-disciplinary knowledge,
required for the design of custom implant

5. Proposed solution
• Virtual Breeding Environment / Virtual Enterprises
• Qualified/certified manufacturing enterprises,
technically coordinated by the broker (focal supplier to
clinical centers)
• Interoperable infrastructures
• Common infrastructure
• Models’ infrastructure
• Systems’ infrastructure
• Individual enterprises’ information systems

8. Semantic interoperability issues
• In single domain environment
• Logical relations between the micro-steps carried out
during the surgery and spatial features of the bones
(location, arrangement) (CIS – PRE-OP-Sys)
• Logical relations between anesthesia planning and EHR
entities (CIS – PRE-OP-Sys)
• Logical relations between spatial features of the bones
and implant design (CIS – IMPL-D-Sys)
• In cross-domain environment
• Interoperability between IMPL-D-Sys and VBE systems

10. Processes
• Pre-operation planning service
• Design of the implant service
• Sourcing, manufacturing and delivery of scaffold
and inner fixture products, engineered to order
• Sourcing, implementation and delivery of services
of digital reconstruction of traumatized bone and
analysis of bio-mechanical properties of the
implant
• Sourcing and implementation of the ethical
committee review and delivery of review results
