Why queuing never vanishes

This tutorial aims to address and illustrate that queuing theory has a wider potential than generally perceived, while at the same time a variety of practical problems, both in daily-life and industry, are open for fundamental research. To this end, it will: (i) Highlight basic queuing insights for daily-life purposes. (ii) Provide exact and bounding results for queuing network applications. (iii) Present a number of practical illustrations (case studies) taken from areas such as: Daily-life situations (postal offices and supermarkets); Transportation (railways and air-traffic); Administrative logistics (reengineering); Telecommunications (call-centers).
