conclusions using the simulation as a decision making tool helps us to decide how we can reduce outpatient's waiting time. comparison of outputs of this scenario and the based- case scenario in simulation model shows that combining physician's work time changing with patient's admission time changing (scenario 9) would reduce patient waiting time about 73.09%. due to dynamic and complex nature ...

abstract introduction: the amount of waiting time is an indicator of level of access to hospital services and can be measured as one of the indicators of the effectiveness of hospital performance. this study aimed to determine the average waiting time in shahid rahnamoon and afshar clinics. methods: this descriptive, analytical, cross – sectional study was conducted with a simple size of 264 pa...

introduction: emergency department is one of the most important hospital wards that offers emergency services to unstable patients 24 hours a day, 7 days a week. however, the way the services are offered reflects the general status of the hospital since patients with the most serious problems frequently refer to the emergency department. emergency department waiting time is one of the indices u...

in the current seismic data acquisition techniques, sources are fired with large time intervals in order to avoid interferences between the responses of successively firing sources, measured by the receivers. this leads to a time-consuming and expensive survey. theoretically the waiting time between two successively firing sources has to be infinite, since the wavefield never vanishes completel...

conclusions according to the results, there was a direct correlation between access to physical space in ed and waiting time. in addition, improving the physical access did not necessarily result in shorter waiting time. therefore, to improve triage process, improvement of waiting time indices, and modifying forms of work process in ed are recommended. results the correlation between the waitin...

the purpose of this study is estimate waiting time of frost occurrence over iran. the daily data from 663 synoptic and climatology over iran during 1/1/1340 to 11/10/1383 have been used. data interpolated by kriging method on 15ã—15 km pixels. the data base with dimension 15992ã—7187 obtained that on the rows were days and on the column were pixels. by t student test the interval mean of waitin...

Suppose that you are going to school and arrive at a bus stop. How long do have wait before the next arrives? Surprisingly, it is longer—possibly much longer—than what might guess from looking schedule. This phenomenon, which called waiting-time paradox, has purely mathematical origin. In this article, we explore explain why occurs, discuss some of its implications (beyond possibility being lat...
