【正文】 imization 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。 materials management of information is not accurate, the resources of its own hospitals unknown, the backlog caused by waste, And were not the best use. HIS use of realtime management of financial documents, stores, medicines to solve the above problem is an effective way. Drugs such as the management, use of the country under the GSP management standards, making local hospitals in the drug supply management and the validity of drug management, and other areas more convenient norms, greatly enhance the safety of hospital treatment. The hospital information system operate effectively, could significantly enhance the department39。s office to arrange for optimal design, to obtain essential characteristics of their systems to reflect the number of indicators of results, forecast, analysis or evaluation, the maximum to meet the needs of patients and their families, will effectively avoid waste of resources. Through the queuing theory to the shortage of hospital business analysis, a puter management system for hospital use is inevitable, the report shows that implementation of information management can enhance the overall image of the hospital, the hospital people to effectively feel the standardization and modernization Management, enhance the local hospital in the influence of petitiveness, so as to enhance the economic benefits of the hospital。 Hospital is a plex system, from the registered patients, medical, designated prices, get medicine each service agencies, when a service of the existing demand for the services provided over the existing capacity, will take place in the queue, because of the arrival of Time and time required for diagnosis and treatment of patients with the randomness, controllability small, the queue is almost inevitable, when the Clinic is insufficient, and often appear in the queue waiting time is too long, patient satisfaction declined, medical personnel, too hurry, easy to Error patient disputes arising from the patients and the munity will have an adverse impact. So how reasonable scientific and medical equipment for medical staff, hospital doctors and will not blindly increase unnecessary idle equipment, a waste of resources, so that patients wait as much as possible to reduce the time, how to strike a balance between, In order to improve service quality, reduce service costs, this is a modern hospital administrators must face the issue. queuing theory model, through mathematics and quantitative methods, the objective of a plex system of queuing behavior of the structure and dynamic simulation studies, science, and accurately describes the probability of the queue, the queue of operations research is an important branch of [ 1, 2]. In hospital management, if the queuing theory on the basis of the hospital outpatient, the queuing system39。 醫(yī)院信息管理系統(tǒng)不僅僅只是醫(yī)院管理現(xiàn)代化的標志 ， 更重要的是已經(jīng)成為醫(yī)院的核心競爭能力之一 ， 成為醫(yī)院持續(xù)性發(fā)展的一個重要組成部份 。這是對幾十年來傳統(tǒng)醫(yī)療管理的挑戰(zhàn)，只有建立
