Computerized Maintenance Management System (CMMS)

Maintenance management driven by real equipment performance, dimensional quality and QIF (ISO 23952) integration

IVR CMMS plans and controls maintenance activities using real availability and performance data from OEE, combined with dimensional results automatically collected from IMTE — Inspection Measuring and Test Equipment. Work orders are linked to QIF-structured characteristics and SPC behavior, ensuring that maintenance decisions are supported by measurable evidence and full traceability.

Maintenance with measurable impact

  • Work orders linked to real OEE availability losses
  • Dimensional quality indicators from IMTE measurements
  • QIF-structured characteristics associated with equipment behavior
  • SPC-based detection of process instability after maintenance
  • Integrated CAD + QIF + DMIS digital thread

Maintenance planning based on real performance data

IVR CMMS uses OEE data to identify availability and performance losses that indicate the need for preventive or corrective maintenance.

Instead of relying solely on time-based intervals, maintenance planning incorporates real execution metrics captured from MES and equipment monitoring.

Maintenance activities are aligned with measurable equipment behavior.

Dimensional evidence supporting maintenance decisions

Dimensional results collected from IMTE — Inspection Measuring and Test Equipment provide objective indicators of equipment condition, such as drift, repeatability issues or process instability.

These results are structured in QIF (ISO 23952) and linked to specific machines, tools and components, enabling root cause analysis based on measured characteristics.

  • Characteristic-level degradation tracking
  • Correlation between dimensional drift and machine condition
  • Traceable link between maintenance action and measured outcome

Integration with MES and SPC after intervention

After maintenance intervention, SPC monitoring validates process stability and capability. Control charts and Cp/Cpk indices are associated with the related maintenance work order.

This ensures that corrective actions restore dimensional performance and do not introduce new variability.

Maintenance effectiveness is verified by statistical evidence.

Continuous digital thread in asset management

Engineering definitions from CAD are structured in QIF and executed via DMIS programs. Dimensional outputs from IMTE feed MES, OEE and CMMS modules without manual re-entry.

The digital chain — CAD → QIF → DMIS → IMTE → MES → OEE → CMMS — ensures consistency between engineering intent, measured results and maintenance decisions.

  • Design-to-asset traceability
  • Alignment between dimensional definition and maintenance records
  • Documented and auditable maintenance history

Audit-ready maintenance records

All maintenance plans, interventions and validation results are stored as structured, retrievable records.

By integrating maintenance management with real dimensional evidence, IVR CMMS ensures technically defensible and fully traceable asset control.

Maintenance becomes a data-driven and measurable engineering process.
