customer which exceeds its deadline will either leave the queue without service or stay in the queue to get unsucWe consider the problem of scheduling impatient CUScessful service. One application of this problem is the tomers in a non-preemptive G/GI/1 queue. Every CUStransmission of time-constrained messages over a comtomer has a random deadline to the beginning of its munication channel. The...

We explore the issue of when and how to partition arriving customers into service groups that will be served separately, in a first-come first-served manner, by multi-server service systems having a provision for waiting, and how to assign an appropriate number of servers to each group. We assume that customers can be classified upon arrival, so that different service groups can have different ...

Customers arriving at a queue do not usually see its time-average behavior unless arrivals occur according to a Poisson process. In this article we study how nearly customers see time-average behavior. We give total variation error bounds for comparing the distance between the timeand customer-average distributions of a queueing system in terms of properties of the interarrival distribution. So...

We consider systems comprised of two interlacing M/M/ • /• type queues, where customers of each queue are the servers of the other queue. Such systems can be found for example in file sharing programs, SETI@home project, and other applications (see e.g. Arazi, Ben-Jacob and Yechiali (2005)). Denoting by Li the number of customers in queue i (Qi), i = 1, 2, we assume that Q1 is a multi-server fi...

It takes time to process purchases and as a result a queue of customers may form. The pricing and service rate decisions of a monopolist who must take this into account are characterized. We nd that an increase in the average number of customers arriving in the market either has no e ect on the monopoly price, or else causes the monopolist to reduce the price in the short run. In the long run t...

The Internet gives incredible opportunities for companies to learn about their consumers. Most managers view learning as actively asking questions directly to consumers and listening to their responses. Alternatively, managers can passively learn by observing the choices that consumers make. Passive learning techniques include user profiling, collaborative filtering, path analysis, and conjoint...

The following paper presents a case study conducted for a non profit organisation (BSU). BSU is a student organisation from Fribourg, Switzerland that regularly organises stock market simulations for students. The purpose of this case study was to analyse participants using a hierarchal fuzzy classification. After a brief overview of BSU, different methods for analysing online customers are ana...
