Queuing is a common phenomenon in theme parks which negatively affects visitor experience and revenue yields. There is thus a need for park operators to infer the real queuing delays without expensive investment in human effort or complex tracking infrastructure. In this paper, we depart from the classical queuing theory approach and provide a data-driven and online approach for estimating the ...
Network and processing overhead associated with web services is a significant challenge to its performance. As a result, web service providers often announce a service level agreement. This ensures that consumers, who pay for the service, can get the service at a given quality level. In this paper, we study the competition between two providers offering functionally the same web services, whe...
Queuing theory is used to model many systems in different fields in our life; it is used in simple systems and complex ones. The main idea in the application of a mathematical model is to measure the performance measures of the application in order to improve the performance of the system. This paper will present an analytical method and simulation modelin estimation the appropriate model for a...
Typing is one of the basic and prevalent activities in human machine interaction. John (1988, 1996) proposed a PERT (Project-Evaluation-Research-Technique)-based model called TYPIST, which modeled 21 of the 31 behavioral phenomena in transcription typing (Salthouse, 1986, 1987; Gentner, 1983). However, TYPIST can only analyze the typing phenomena along the time dimension; it can not model error...
This paper aims to find the optimal arrangement of consultation rooms in the specialist outpatient clinics of a hospital in Singapore to maximize the utilization factor. Doctors’ utilization and waiting time of the patients were also optimized in this research. This was done by building and validating queuing and simulation models to predict and model the real life variance and uncertainty in t...

We consider a multiserver queuing process speciied by i.i.d. interarrival time, batch size and service time sequences. In the case that diierent servers have diierent service time distributions we say the system is heterogeneous. In this paper we establish conditions for the queuing process to be characterized as a geometrically Harris recurrent Markov chain, and we characterize the stationary ...
In this paper we consider a queuing system in which the service times of customers are independent and identically distributed random variables, the arrival process is stationary and has the property of orderliness, and the queue discipline is arbitrary. For this queuing system we obtain the steady state second moment of the queue size in terms of the stationary waiting time distribution of a s...
