Reliabilty Analysis of Multi-State Series System

Abstract

Reliability Analysis considering Multiple Possible States is known as Multi-State Reliability Analysis. Multi-State System Reliability Models allow both the System and its Components to assume more than two levels of performance. Though Multi-State Reliability Models provide more realistic and more precise representation of Engineering System, they are much more complex and present major difficulties in System definition and performance evaluation. This paper presents a new Systematic Approach for the Reliability Analysis of Multi-State Series System which helps to determine the Expected Throughput and Performance-Free Failure Operation (PFFO) of the System. This Approach is applied to a Mathematical Model dealing with a Particular Population, being categorized into four groups based on their Haemoglobin level and the Health Status of the Population under Study is analyzed.
