Condition-Based Maintenance (CBM)
Maintenance strategy where actions are triggered based on the actual condition of the equipment, measured by sensors and performance indicators, rather than on a predefined schedule.
Alert Threshold
Predetermined value of a measured parameter that, once reached or exceeded, triggers a notification or maintenance action to prevent a failure.
Business Rule
Set of logical conditions, defined by domain experts, that guide automated maintenance decisions based on the interpretation of operational data.
Condition Indicator (CI)
Specific quantitative or qualitative measurement, such as temperature or vibrations, used to assess the health status of an asset and predict its future degradation.
Conditional Triggering
Activation of a maintenance intervention only when a set of predefined conditions, based on real-time data, are satisfied.
Trend Analysis
Examination of the evolution of a condition indicator over time to identify degradation patterns and anticipate when a critical threshold will be reached.
Tolerance Limit
Upper or lower boundary of an acceptable operating range for a given parameter, beyond which the risk of failure increases significantly.
Condition Monitoring System (CMS)
Integrated set of sensors, hardware, and software designed to continuously collect, analyze, and display equipment condition data.
Conditional Diagnosis
Process of identifying the root cause of a detected anomaly based on the analysis of condition data and associated business rules.
Key Performance Parameter (KPP)
Specific and essential measurement that directly reflects the health status or critical performance of equipment in a condition-based maintenance context.
Trigger Logic
Algorithm or set of rules (e.g., AND, OR, IF-THEN) that combines multiple condition indicators to make an automated decision to initiate maintenance.
Maintenance Window
Planned time period during which a condition-based maintenance intervention can be performed with minimal impact on operations, once an anomaly is detected.
Threshold Calibration
Process of adjusting and validating alert threshold values to ensure they are sensitive to actual failures while minimizing false alerts.
Operating Profile
Set of typical operating conditions (load, speed, environment) of equipment, used to contextualize condition data and refine trigger rules.
Failure Mapping
Systematic analysis that links specific failure modes to condition indicators and their respective thresholds to create a targeted alert system.
Setpoint Value
Target or nominal value for an operational parameter, whose deviation can be an early indicator of degradation, used in condition-based approaches.
Measurement Interval
Frequency at which sensor data is collected to assess equipment condition, a crucial parameter for the responsiveness of condition-based maintenance.
