Not so long ago, information technology (IT) risk occupied a small corner of operational risk – the opportunity loss from a missed IT development deadline. Today, the success of an entire financial institution may lay on managing a broad landscape of IT risks. IT risk is a potential damage to...

Abstract In this paper the reliability analysis of two new models generalizing the m -consecutive- k -out-of- n : F system is carried out using GERT: Model I: m -consecutive- k -out-of- n : F system with ( k -1)-step Markov dependence, and Model II: m -consecutive- k -out-of- n : F system with...

Security in power systems refers to the ability of the system to withstand imminent disturbances (contingencies). Maintaining security is an issue which must be addressed at the system level. It is shown in this paper, however, that it is possible to maintain power system security in an...

We consider Markov Modulated Bernoulli Processes (MMBP) where the success probability of a Bernoulli process evolves over time according to a Markov chain. The MMBP is applied in reliability modeling where systems and components function in a randomly changing environment. Some of these...

Lifelines are networks extending spatiallyover large areas. Transportation systems, pipelines,communication and power transmission systems areexamples of lifelines. The performance of a lifelineafter a major earthquake is particularly vital for acommunity because of the emergency services that...

Implementation of IT Service Management (ITSM) processes as prescribed by the Information Technology Infrastructure Library (ITIL) or in Microsoft Operation of Framework (MOF) can be a difficult undertaking. The Regis University Networking Lab Practicum (NLP) has opted to align its current IT...
