INTRODUCTION FOR RELIABILITY ENGINEERING
- Reliability Engineering is a discipline focused on ensuring that systems and components perform their intended function without failure over a specified period of time and under stated conditions.
- It plays a critical role in product design, manufacturing, and maintenance by identifying potential failure modes and implementing strategies to mitigate them.
- This training provides practical tools and techniques to predict, analyze, and improve the reliability of products and processes, ultimately enhancing performance, safety, and customer satisfaction.
LEARNING OBJECTIVES
In this course, the participants will :
- Understand the fundamental concepts and significance of reliability engineering in design, manufacturing, and maintenance.
- Apply key reliability metrics and statistical models to assess and predict system performance and failure behavior.
- Utilize practical tools such as FMEA, FTA, and Weibull analysis for failure analysis and decision-making.
- Develop and implement effective reliability testing strategies, including accelerated life testing and reliability growth modeling.
- Integrate reliability principles into maintenance planning using Reliability-Centered Maintenance (RCM) and lifecycle cost analysis.
LEARINING METHODOLOGY
- Activities, discussions, videos and case studies with frequent activities & quiz for a deeper understanding.
