Reliability Engineering Principles for the Plant Engineer


The purpose for quantitative reliability measurements is to define the rate of failure relative to time and to model that failure rate in a mathematical distribution for the purpose of understanding the quantitative aspects of failure. The most basic building block is the failure rate, which is estimated using the following equation: Where:

Reliability Analysis of the Engineering Systems Using ...


The present paper investigates the reliability analysis of industrial systems by using vague lambda-tau methodology in which information related to system components is uncertain and imprecise in nature. The uncertainties in the data are handled with the help of intuitionistic fuzzy set (IFS) theory rather than fuzzy set theory. Various reliability parameters are addressed for strengthening ...

Basics of System Reliability Analysis - ReliaWiki


Reliability Block Diagrams (RBDs) Block diagrams are widely used in engineering and science and exist in many different forms. They can also be used to describe the interrelation between the components and to define the system. When used in this fashion, the block diagram is then referred to as a reliability block diagram (RBD).

Reliability Allocation in Parallel – Series Systems


1- The reliability allocation is depending on the way with which the elements of the system are connected. 2- The process considered in this paper is the converse of that for calculating the system reliability. 3- This method used to calculate the reliability allocation for more general structure of parallel - series systems.
