Patients nationwide experience difficulties in accessing medical appointments in a timely manner due to long backlogs. Meanwhile, patients do not always show up for their scheduled services, with significant no-show rates. Unattended appointments result in under-utilization of a clinic’s valuable resources, and limit the access for other patients who could have filled the missed slots. Medical ...

Patient no-shows and cancellations are a significant problem to healthcare clinics, as they compromise clinic's efficiency. Therefore, it is important account for both into the design of appointment systems. To provide additional empirical evidence on no-show cancellation behaviour, we assess outpatient clinic data from two providers in USA EU: rates increase with scheduling interval, which num...

In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...

This paper deals with the G/G/R machining system consisting of M operating machines as well as S cold standbys. The concepts of balking and reneging are incorporated which make our model more versatile to deal with real time systems. The broken-down machines are sent to repair facilities consisting of R permanent repairmen. The failure times and repair times are generally identical and independ...
