We present a brief introduction to three reliability engineering techniques: failure mode, effects, and criticality analysis; reliability block diagrams; and fault tree analysis. We demonstrate the use of one of these techniques, reliability block diagrams, in evaluating the availability of information technology (IT) systems through a case study involving an IT system supported by a three-tier Web-server configuration.
This paper provides a general introduction to the simulation technique and the simulation language SLAM II. The use of simulation modelling and in particular SLAM II is demonstrated by way of an illustrative example consisting of the building and manipulation of a simulation model of a materials handling subsystem of a beer brewing and packaging plant. The purpose of the model is to investigate the influence of the number of loading and unloading docks on various measures of system performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
