CC4003 Reliability in Engineering Systems Syllabus:

CC4003 Reliability in Engineering Systems Syllabus – Anna University PG Syllabus Regulation 2021

COURSE OBJECTIVES:

1. The ability to use statistical tools to characterize the reliability of an item;
2. The working knowledge to determine the reliability of a system a
3. To suggest approaches to enhancing system reliability;
4. The ability to select appropriate reliability validation methods

UNIT– I RELIABILITY CONCEPT

Reliability definition – Quality and Reliability– Reliability mathematics – Reliability functions – Hazardrate–Measures of Reliability–Design life–Apriori and posteriori probabilities– Mortality of a component–Bath tub curve–Usefullife.

UNIT– II FAILURE DATA ANALYSIS

Data collection –Empirical methods: Ungrouped/Grouped, Complete/Censored data – Time to failure distributions: Exponential, Weibull– Hazard plotting– Goodness offittests.

UNIT–III RELIABILITYASSESSMENT

Different configurations–Redundancy–m/nsystem–Complex systems: RBD–Baye’s method– Cut and tie sets–Fault Tree Analysis–Stand by system.

UNIT– IV RELIABILITY MONITORING

Life testing methods: Failure terminated – Time terminated – Sequential Testing – Reliability growth monitoring–Reliability allocation–Software reliability.

UNIT– V RELIABILITY IMPROVEMENT

Analysis of downtime – Repair time distribution – System MTTR – Maintainability prediction – Measures of maintainability–System Availability–Replacement theory.

COURSE OUTCOMES:

 Analyse the interference between strength and stress, or life data for estimating reliability;
 Apply the appropriate methodologies and tools for enhancing the inherent and actual reliability of components and systems, taking into consideration cost aspects; specify life test plans for reliability validation
