Summary
This study integrates metrology and research methods to create a system for analyzing periodic maintenance intervals. Understanding device failure modes like random and time-related failures is crucial for preventing predictable failures and optimizing maintenance schedules.
Area of Science:
- Metrology and Engineering
- Reliability Engineering
Background:
- Current maintenance practices often lack a systematic approach to interval determination.
- Integrating metrological principles can enhance the scientific basis of maintenance planning.
Purpose of the Study:
- To develop a periodic maintenance interval analysis system.
- To establish a framework for optimizing device maintenance schedules based on quality indicators and failure modes.
Main Methods:
- Integration of metrological methods and research principles.
- Utilization of engineering endpoints as measurement attributes.
- Identification and analysis of two primary failure modes: random and time-related failures.
Main Results:
- Defined accuracy and reliability as key quality indicators for maintenance.
- Established a system for periodic maintenance interval analysis.
- Demonstrated the importance of recognizing failure modes for effective maintenance.
Conclusions:
- A systematic approach to maintenance interval analysis is essential for preventing device failures.
- Understanding time-related failures allows for proactive and predictable maintenance scheduling.
- The developed system provides a basis for averting predictable and preventable device failure.
