<p style='text-indent:20px;'>In this paper, a queuing system as multi server queue, in which customers have a deadline and they request service from a random number of identical severs, is considered. Indeed there are stochastic jumps, in which the time intervals between successive jumps are independent and exponentially distributed. These jumps will be occurred due to a new arrival or situation change of servers. Therefore the queuing system can be controlled by restricting arrivals as well as rate of service for obtaining optimal stochastic jumps. Our model consists of a single queue with infinity capacity and multi server for a Poisson arrival process. This processes contains deterministic rate <inline-formula><tex-math id="M1">\begin{document}$ \lambda(t) $\end{document}</tex-math></inline-formula> and exponential service processes with <inline-formula><tex-math id="M2">\begin{document}$ \mu $\end{document}</tex-math></inline-formula> rate. In this case relevant customers have exponential deadlines until beginning of their service. Our contribution is to extend the Ittimakin and Kao's results to queueing system with impatient customers. We also formulate the aforementioned problem with complete information as a stochastic optimal control. This optimal control law is found through dynamic programming.</p>

Healthcare is a fast growing industry demanding perfection, top notch services and optimal utilization of available resources. Despite shortages in doctors and nurses as well as frequent overcrowding, the number of incoming patients to the government hospitals is increasing every year. The outpatient department in Malaysian Government hospitals is consistently experiencing frequent congestion particularly in the morning. The challenge for hospital administrators is to rightly and timely allocate resources in relevant departments. Henceforth, this study aims to further gauge the performance of an outpatient department in a local hospital in Kedah. In particular, it aims to investigate the current efficiency level of a queuing system of the said department and to propose potential solutions. The study uses Multi-server Queuing Models (M/M/s) to measure the performance of the waiting line. A computational work is then presented to value the operating characteristics of the model. The findings exhibit the performance of existing queuing system and the need to re-examine the number of doctors on duty. In all, the study may be beneficial as a decision making aid to the administrator of the outpatient department particularly to re-look and improve existing queuing system in tandem with the center’s commitment for better customer satisfaction and minimal patients’ turnover.
