Data envelopment analysis (DEA) is a powerful nonparametric engineering tool for estimating technical efficiency and production capacity of service units. Assuming an equally proportional change in the output/input ratio, we can estimate how many additional medical resource health units would be required if number hospitalizations was expected to increase during epidemic outbreak. This assessment proposes two-step methodology hospital beds vacancy reallocation COVID-19 pandemic. The...
Current Internet transport protocols are being revisited in an attempt to respond traffic growth size, diversity and the emergence of new applications. Designed reduce Web TCP latency connection establishment time, QUIC uses UDP defines its own congestion control. To verify some QUIC's performance claims, we carried out extensive set controlled experiments reflecting conditions by configuring various parameters, such as round trip time (RTT), packet loss ratio, web pages, caching....
The Internet is one of the most important innovations humanity and has brought many our social cultural changes. web pages have great importance because they are opening door for which users can interact directly with each other corporations. A bad performance may result in a significant loss from millions users. This work aims to evaluate through Data Envelopment Analysis (DEA), provide list 82 100 most-accessed addresses world ranked by their page load time (output) projection on size...
Abstract For strategic reasons, benchmarking best practices from efficient competitors is not usual in many data envelopment analysis (DEA) applications. Even for industries composed of multiple branches, providing information about their peers can jeopardize results those branches if they compete market, resources or recognition by the central administration. In this work, a time‐series adaptation DEA directional model proposed as an alternative coping with problem. The methodological...
A misincentive is characterized as an incentive producing the opposite effect of motivating or preventing some specific action. In circumstances, contract penalties such sanctions and fines on late delivery low-quality software encourage irregularities instead them from occurring. The present study models behaviors in Information Technology Outsourcing (ITO) transactions a Principal-Agent problem. Considering non-linear relationship vendors’ cost structure client’s sensitivity to...
Browsing is a prevalent activity on the World Wide Web, and users usually demonstrate significant expectations for expeditious information retrieval seamless transactions. This article presents comprehensive performance evaluation of most frequently accessed webpages in recent years using Data Envelopment Analysis (DEA) adapted to context (inverse DEA), comparing their under two distinct communication protocols: TCP/IP QUIC. To assess disparities, parametric non-parametric hypothesis tests...
