introduction : it is clear that if the discharge process takes less time and the patient leaves the hospital bed earlier, the length of hospitalization, and consequently, the waiting time for admission decreases. therefore, the method of use of treatment facilities is somewhat improved. the hospital discharge process, from when the discharge authorization is issued until the patient leaves the ...

this paper presents a discrete-time single-server finite buffer n threshold policy queue with renewal input and discretemarkovian service process. the server terminates service whenever the system becomes empty, and recommencesservice as soon as the number of waiting customers in the queue is n. we obtain the system-length distributionsat pre-arrival and arbitrary epochs using the supplementary...

PROBLEM Most patients with advanced lung cancer currently receive much of their health care, including chemotherapy, as outpatients. Patients have to deal with the complex and time consuming logistics of ambulatory cancer care. At the same time, members of staff often waste considerable time and energy in organisational aspects of care that could be better used in direct interaction with patien...

background: hospital emergencies have an essential role in health care systems. in the last decade, developed countries have paid great attention to overcrowding crisis in emergency departments. simulation analysis of complex models for which conditions will change over time is much more effective than analytical solutions and emergency department (ed) is one of the most complex models for anal...

Background It is experienced in emergency department waiting time to a course of treatment becomes longer due to lack of communication and patient planning. By optimizing the communication between doctors and nurses the waiting time for patients can maybe be reduced. The emergency department triage patients in category 1 to 5. Category 1 is most emergent. We selected two patient groups, categor...

We propose a model for disorderly streetcar routes. Through simulations and comparisons to real data, we illustrate that such routes may sometimes become supersaturated, in the sense that forward and backward waiting times become positively correlated.
