This paper describes a duopoly market for healthcare where one of the two providers is publicly owned and charges a price of zero, while the other sets a price so as to maximize its profit. Both providers are subject to congestion in the form of an M/M/1 queue, and they serve patient-consumers...

Utilizing a cyclic queue system, this paper investigates the effect of variance on a multi-item production facility. The variance of setup time, service rate and arrival rate is shown to have a powerful and sometimes paradoxical influence. Reduction in setup time, for example, is usually...

The performance of single-server queues with independent interarrival intervals and service demands is well understood, and often analytically tractable. In particular, the M/M/1 queue has been thoroughly studied, due to its analytical tractability. Little is known, though, when autocorrelation...

Sarkar and Zangwill (1991) showed by numerical examples that reduction in setup times can, surprisingly, actually increase work in process in some cyclic production systems (that is, reduction in switchover times can increase waiting times in some polling models). We present, for polling models...

In the early 1990s, research began to show that the Japanese production theory, which espouses reduction of machine setup time as a sure way to improve production performance, may be limited. Specifically, it was found that reduction in mean setup times without any change in variance can,...

This paper analyzes the impact of type of insurance, income, and reason for appointment on waiting time for an appointment and waiting time in the physician’s practice in the out- patient sector. Data were obtained from a German patient survey conducted between 2007 and 2009. We differentiated...

Cost sharing represent a well-established tool for the control of health care demand in many Oecd countries, even though it is used with caution, and in combination with other instruments, in order to avoid potential negative impacts on access to essential health care services. Waiting lists and...

This paper studies how congestion in the public health sector can be used as a redistributive tool. In our model, agents differ in income and they can obtain a health service either from a congested public hospital or from a non congested private one at a higher price. With pure in-kind...
