While mean time to data loss (MTTDL) provides an easy way to estimate the reliability of redundant disk arrays, it fails to take into account the relatively short lifetime of these arrays. We analyzed five different disk array organizations and compared the reliability estimates obtained using their mean times to data loss with the more exact values obtained by directly solving their correspond...

results responsiveness, effectiveness, and flexibility with eigenvalue of 2.628 were identified as the main aspects of agility in humanitarian health supply chains. the components of visibility, reactivity, and speed were identified as components of responsiveness. quality, reliability, and completeness were identified as components of effectiveness. volume, delivery, mix, and product were know...

This paper discusses a discrete event simulation model for the availability analysis of weapon systems. This model incorporates missions, operational tasks and system reliability structures to analyze the availability of a weapon system. The proposed simulation model consists of 5 modules: Simulation Engine, Maintenance Organizations, System, its Mission Profile and RBD which are based on missi...

In many businesses, LANs have displaced older, paper-based methods of doing work, and these organizations now depend on the reliability and availability of their computer networks for the continuity and efficiency of daily operations. Reliability refers to a LAN's capacity to operate despite failures in communications links and equipment. Availability is a measure of performance; it refers to t...

Abstract In dynamic markets, organizations have to be ambidextrous adapt constant change. Simultaneously, are increasingly required adopt quality management accreditation. Standardization through accreditation bares the risk of limiting an organization’s capabilities. this study, we aim evaluate determinants organizational decision-making seek and pursue innovation activities, whether activitie...

Emergency preparedness, planning, and response suffer from shortcomings that impede the potential for effectiveness. In this article, we provide an overview of Emergency Preparedness and Management that is based upon our research, including insights into the shortcomings of current practices, a discussion of relevant theories (e.g., High Reliability Organizations, muddling through) and recommen...

Abstract To improve organisational safety and enhance security efficiency, organisations seek to establish a culture of that provides foundation for how employees should approach security. There are several frameworks models provide set requirements forming cultures; however, many organisations, the difficult meet, if not impossible. In this research, we take different perspective focus on core...
