This paper presents a mathematical model and simulated annealing heuristics for assigning activities to workspaces and resources (e.g., equipment, parts, and toolboxes) to work/storage spaces during planned outages at electric power plants. These assignments are made such that the distance resources (toolboxes) travel throughout the duration of the outage is minimized. This problem is defined a...

In our everyday lives, we create massive amounts of data. But how much does it really cost to store data? With ever decreasing cost of storage media, a popular misconception is that the cost of storage has become cheaper than ever. However, we argue that the cost of storing data is not equal to the cost of storage media alone – rather, many often ignored factors including human, infrastructure,...

Infrastructure as a Service is a provision model in which a Cloud Service Provider (CSP) outsources the equipment used to support operations, including storage, hardware, servers and networking components. In such an service model customer stores his/her information in the hands of service providers, the insider attacker, hacking etc are vital corners to be handled, many have proposed solutions...

File replication for uninterrupted availability is affected by the localised nature of network failures, particularly in ubiquitous, mobile environments; nearby nodes often get disconnected together, as a result of switching equipment faults, or of local wireless network unavailability – for instance, failure of a base station, or loss of network connectivity when a train enters a tunnel. In th...

An automatic test pattern generation (ATPG) method is presented for a scan-based test architecture which minimizes ATE storage requirements and reduces the bandwidth between the automatic test equipment (ATE) and the chip under test. To generate tailored deterministic test patterns, a standard ATPG tool performing dynamic compaction and allowing constraints on circuit inputs is used. The combin...

We will present a progress report on our effort to develop a science-based design methodology for warehousing systems. In particular, we will discuss the hierarchical structure of our design procedure. This includes the decisions and parameters used in the master model, the various sub-models, and the decision and data interaction between the various levels in the hierarchy. We will present sev...

The emergence of the Internet and personal computers has led to an age of unprecedented information access. The proliferation of Internet connectivity, personal computers, and portable, high density data storage has put volumes of data at one's ngertips. While the spread of such technology has increased e ciency and knowledge, it has also made information theft easier and more damaging. One com...
