Forecast Errors in Service Systems
We investigate the presence and impact of forecast errors in the arrival rate of customers to a service system. Analysis of a large dataset shows that forecast errors can be large relative to the fluctuations naturally expected in a Poisson process. We show that ignoring forecast errors typically leads to overestimates of performance and that forecast errors of the magnitude seen in our dataset...
متن کاملA transmission availability forecast service for Internet protocol networks
The quality of available network connections, especially the bandwidth available to clients using the connections, has a large impact on the performance of distributed applications. For example, document transfer applications such as the World Wide Web suffer a dramatic increase in response times as a result of network congestion causing a reduction in the available bandwidth of the connection....
متن کاملDeveloping a Heatwave Early Warning System for Sweden: Evaluating Sensitivity of Different Epidemiological Modelling Approaches to Forecast Temperatures
Over the last two decades a number of heatwaves have brought the need for heatwave early warning systems (HEWS) to the attention of many European governments. The HEWS in Europe are operating under the assumption that there is a high correlation between observed and forecasted temperatures. We investigated the sensitivity of different temperature mortality relationships when using forecast temp...
متن کاملDevelopment of health risk-based metrics for defining a heatwave: a time series study in Brisbane, Australia
BACKGROUND This study attempted to develop health risk-based metrics for defining a heatwave in Brisbane, Australia. METHODS Poisson generalised additive model was performed to assess the impact of heatwaves on mortality and emergency hospital admissions (EHAs) in Brisbane. RESULTS In general, the higher the intensity and the longer the duration of a heatwave, the greater the health impacts...
متن کاملThe Excess Heat Factor: A Metric for Heatwave Intensity and Its Use in Classifying Heatwave Severity
Heatwaves represent a significant natural hazard in Australia, arguably more hazardous to human life than bushfires, tropical cyclones and floods. In the 2008/2009 summer, for example, many more lives were lost to heatwaves than to that summer's bushfires which were among the worst in the history of the Australian nation. For many years, these other forms of natural disaster have received much ...
