In this paper, the performance of a telephone system in which there are both patient and impatient customers is studied. Depending on the waiting time in the buuer, a customer may become impatient and therefore the call is incomplete. A impatient customer still consumes real processing time. The impact of impatient customers on the system is much more remarkable than people would expect. We for...

Sixty dropouts from hypertensive clinics were interviewed in depth to determine reasons for noncompliance. Waiting time and a poor doctor-patient relationship were the major reasons given. The average waiting time prior to examination by the doctor was 2.5 hours, and the average waiting time at the pharmacy was 1.8 hours. In contrast the average time spent with the doctor was 7.5 min. The poor ...

INTRODUCTION Oral diseases may have an impact on quality of children's life. The presence of severe disability requires the use of care under general anesthesia (GA). However, because of the limited number of qualified health personnel, waiting time before intervention can be long. AIM To evaluate the waiting time before dental care under general anesthesia for children with special needs in ...

This study analyzes the waiting lines for solid organ transplants in Brazil's Unified National Health System. By using a queuing theory model, we estimate the waiting times for different organs under alternative scenarios. The model reveals the elasticity of various waiting times with respect to arrival and service rates for organ transplantation within the system. Average waiting time for a so...

The objective of this paper is to analyze service reliability of bus rapid transit (BRT) taking Changzhou BRT as an example. Headway irregularity, potential waiting time, equivalent waiting time, and reliability buffer time are recommended to measure service reliability of BRT. Temporal and spatial distributions and comparisons are analyzed. Findings are that passengers of Changzhou BRT need to...

banking and financial services are important parts of the service industry. quality of service in the banking industry has a close relationship with customer satisfaction service system. banks could create competitive advantage by increasing customer satisfaction and reduce costs in today's competitive environment. this paper presents a decision-making model to obtain optimum tasks assigne...

Many scholars study shows that the background music is restaurant controllable environmental factor that can affect the customer waiting time, which has some management implications for solving customer wait time problem in the service sector. This article used experimental management method, randomly selected a large restaurant, and then observed each customer just coming in, recorded backgrou...

Grid computing enables sharing, selection and aggregation of computing resources for solving complex and large-scale scientific problems. The resources making up a grid need to be managed to provide a good quality of service. Grid scheduling is a vital component of a Computational Grid infrastructure. This paper presents a dynamic cluster based job scheduling algorithm for efficient execution o...

In this paper, a new variant of Round Robin (RR) algorithm is proposed which is suitable for soft real time systems. RR algorithm performs optimally in timeshared systems, but it is not suitable for soft real time systems. Because it gives more number of context switches, larger waiting time and larger response time. We have proposed a novel algorithm, known as Priority Based Dynamic Round Robi...
