Tandem Queues with Impatient Customers for Blood Screening Procedures

Abstract: We study a blood testing procedure for detecting viruses like HIV, HBV and HCV. In this procedure, blood samples go through two screening steps. The first test is ELISA (antibody Enzyme Linked Immuno-Sorbent Assay). The portions of blood which are found not contaminated in this first phase are tested in groups through PCR (Polymerase Chain Reaction). The ELISA test is less sensitive than the PCR test and the PCR tests are considerably more expensive. We model the two test phases of blood samples as services in… Show more

“…In the next example, we consider several Markov chains that come from tandem queuing networks [1] . Tandem queuing networks have been applied in wireless networks [30] and blood screening procedures [5] . For each tandem queuing network, there are two finite queues with single-servers, customers arrive according to a Poisson distribution with rate μ, and the service time distributions at the two single-server stations are Poisson with rates μ 1 and μ 2 , respectively [7] .…”

“…Tandem queuing network exists in some practical applications, for example, in wireless networks [25] and blood screening procedures [26]. Following the settings and description in [17], we consider the situation that there are two finite queues with single servers, customers arrive according to a Poisson distribution with rate , and the service time distribution at the two single-server stations is Poisson with rates 1 and 2 .…”

“…Tandem queueing networks, where customers need to visit several stations in sequence, abound in the modern economy. Examples range from call centers, where customers talk to general call-takers before being transferred to specialists (see, e.g., Gans et al 2003), to hospital emergency rooms, where patients are admitted by triage nurses before going on to have a number of medical tests and procedures (see, e.g., Zayas-Cabán et al 2013), to cost-efficient blood screenings, where a less sensitive but inexpensive test is conducted before a more sensitive and expensive one (see, e.g., Bar-Lev et al 2013). In these applications, abandonment (i.e., leaving the queue before or while being served) is an important phenomenon.…”
