At the same time improve the accuracy of information to ensure that the Hospital Finance, is zoned price, under doctor39。s orders, and other aspects of the human error rate hits zero, so that the medical staff to release more energy and time to serve the patients and ensure economic interests of the patients at the same time Create economic benefits for the Hospital. 1 Stochastic model In various queuing system, the randomness of them is a mon, but also plays a fundamental role. The arrival time between customers and customer service requirements, at least a random, otherwise the problem too simple. Queuing theory research system described some of the major indicators of the probability distribution, divided into three parts: 1) Queuing system behavior problems Queuing system on the behavior of the problem is the study of the various laws of the probability of queuing system, including captain of the system, the customer waiting time and length of stay, and the busy period, and so the probability distribution, including their transient nature and the balance under the Census and Statistics Behavior. Queue System is the behavior of the core line of research is queuing System of statistical inference and optimization of the foundation. Consider applications from the Census and balance the various indicators of the probability of nature is particularly important. 2) The statistical system queue inference In order to understand and grasp a queuing system is running in the law, through repeated observations, data collection, and then using mathematical statistics by the method of data processing, inferred by observing the law of the probability of queuing system, application of the corresponding The theoretical results to study and solve the queuing system of the problem. Queuing system has been the statistical inference is the oute of the actual application of the basic work, bining the characteristics of queuing system, the development of such special random process of statistical inference is very necessary. 3) Queuing system optimization problem Queuing system optimization problems, including the optimal design and have the best system of operational control, the former are in the service system settings, the future operation of the situation has estimated that the design be based on staff. The latter is already queuing system for optimal operational strategies, such as tools for the Treasury, when the queue of workers receiving too many tools, additional staff, although this increase in the cost of services, but on the other hand, a decrease of tools for workers The waiting time, an increase of the effective production time workers, so the benefits may far exceed the cost of services increased. Queuing theory study and application of knowledge is an objective system to solve the optimal design or operation of management and create a better economic and social benefits. Description To the hospital outpatient for the study, it has the following characteristics: ① input process: the arrival of patients are independent, have arrived in the time interval is random。 certain period of time subject to the arrival of Poisson distribution. ② queuing rules: from the firste, first service, and to wait for the system, namely the arrival of all patients with a doctor39。s office and are not idle, they must wait. ③ services: diagnosis and treatment of patients is independent of each other, subject to the negative exponential distribution. ④ service window: multiserver, C parallel with a desk, desk work independently. Model assumptions and the establishment Assumption of an average of reach for λ, a single help desk services, the average rate (units of time that was the end of several services) μ, the entire service agencies, the average service rate c μ。 system of service intensity
