Queuing Theory and Wait Times
Queuing, otherwise known as waiting in line, is something that most people feel they know how to do, yet struggle with in practice. Efficient queuing is critical for businesses. For airlines and other businesses which provide time-dependent services, queuing is necessary to ensure efficiency. For the Transportation Security Administration (TSA), queuing is also a matter of safety. To ensure all passengers are appropriately screened, the TSA must ensure that flyers are able to wait in an orderly line and receive appropriate direction. Yet when people are forced to wait in line, they are often angry and agitated. This is especially true in situations such as an airport in which passengers may be worried about missing flights or have gotten up very early in the morning, endured a hectic commute, or face other pressures regarding their flight. Waiting in line is yet another inconvenience.
The fact that TSA officials are a representative of a public agency is an added responsibility. If people are treated poorly by TSA officials, this reflects poorly upon public servants and the government agency the officials serve. It may also make otherwise law-abiding citizens think worse of their government...
Moving lines quickly and making the experience a positive one is important. This underlines the psychological dimension of queueing and expediting queuing that is only a factor when dealing with human beings.
As noted by Ferreira (et al. 2011), there are many ways in which inventory can be organized in terms of a queue, such as a first in and last out method, or a last in and first out method. In the case of human beings, efficiency is not always possible. Rather, fairness and perceptions of fairness are; for example, while it can be useful to expedite the passage of some individuals through a queue if they have additional security background checks, this must be weighed with the potential negative of the ire it tends to stir among those who are waiting. Still, even in other industries, there have been attempts to have different waiting and queueing times for people, based upon segmenting their status, as noted by the Institute for Healthcare Improvement (n.d.). For example, individuals with less lengthy appointments may have staggered appointments with those who are being seen for more intensive procedures. While this is…
Managing the Supply Chain Research an extended enterprise supply chain and identify key issues Value driven supply chains are based on a variety of practices and assumptions. They tend to use the supply chain management to create a competitive advantage to improve a company's performance. The benefit of strategic supply chain management is seen in how an enterprise like Wal-Mart has used its supply chain to obtain an advantage over rivals. For
Queues and Waiting Lines The queuing theory is all about the study of contention for the use of resources that are shared but limited. In other words, it is the mathematical study with the use of models to show results and show opportunities that lie within the processes of arrival, service and the departure. It is made up of models and formulas, which give a description of the relationships between service
Excessive Wait Times in Healthcare Literature Review Excessive wait times in healthcare are a problem for both patients and care providers as they affect patient satisfaction, which in turn impacts the job satisfaction of nurses and other care providers (Chan, 2014). Fatigue and overwork can set in for providers if wait time excesses are not adequately addressed, which can lead to higher turnover rates for professionals and higher costs as a result
Queues v System Dynamics In a system there are different entities that are flowing into and accumulate in stocks then they flow out sometimes into another stock. This is just the same as items in a queue or waiting line. However there are some aspects which are different from queue when compare to systems dynamics. Queues are different from the items that are flowing in and out of stocks as characterized
Expression of Distinct Group Identities Social Identity Theory Laboratory Report Simultaneous Expression of Distinct Group Identities Social identity theory holds that an individual's self-esteem is tied to the groups they belong to and accordingly view themselves as having group traits. The existence of group identity was investigated in the present study by interviewing queued drivers after they experienced a suspected outgroup intrusion into the petrol queue ahead of them. Socioeconomic status, in terms
Emergency Room Efficiency Improving Emergency Department Flow by Using a Provider in Triage Emergency room triage plays an essential role in the speed and quality of the emergency room departments. Triage represents only one small part of the process that determines quality of patient care. Emergency rooms can be crowded. Busy times are often unpredictable, making it difficult to avoid bottlenecks in the system. This has an affect on the amount of
