| . Along with the continuously developing of the calculator technique and information processing technique, electronics information culture speed through each aspect of social activities, and change people's life, study and work method gradually. Because the medical science realm is high all countries new technique to fight to be first to develop with applied profession, computer technique is also the ground for each aspect that seeped through medical science realm. The computer provides new technique and motive for the development of modern medical science, the dependence of medical science realm to calculator also strengthens day by day. Along with the development of market economy, circulate the management of realm in drugs in the hospital have to be engaged in various management decision activity. Because the drugs funds took up the big part of hospital fluxion funds, and the category of the drugs many s new product many s enter goods outlet many management link many and complications, therefore the drugs often appear to put off to run short etc. circumstance. This makes the governor do more effective decision to become very difficult, therefore drugs purchase the decision support system of research and development have already become the urgent demand of drugs in the hospital management.This thesis is foundation in some HIS system in hospital and supports system according to the need establishment drugs purchase decision of that hospital.(Decision Support System for Purchasing Medicine, DSSPM)Because hospital already from the welfare type changes direction the third industry conducts, the hospital faces the huge pressure of social competition, for the sake of oneself of perfect and development, the hospital by all means wants to adapt to a market economy, so request a hospital to use the forerunner's management means as assurance. And because the drugs funds took up fluxion funds in most of the hospital, and drugs category many s new product many s enter goods outlet many management link many and complications, therefore the drugs often appear to put off, missing etc. circumstance. This makes the governor of drugs realm in the hospital do more effective decision to become very difficult, so drugs purchase the decision support system of research and development become the urgent demand of drugs in the hospital management. In the meantime hospital also at information-based, is constructing the third generation to take patient as center to take electronics medical history(CPR) as core now of HIS system, and gradual develop toward the fourth generation direction of information system in the intelligence hospital(IHIS).It is irresistible general trend to consequently work out a drugs purchase problem with DSS combine effective. This drugs purchase decision support system for aim at the need of some drugs in the hospital purchase business to buy decision to the drugs support the system carried on thorough study, design and carried out a drugs purchase decision support system of prototype system. The special feature of that system carries on data organization by data warehouse and designed according to the model database of facing to the object technique and apply heredity calculate way to choose at the model and supported the system structure of system's carrying on to lately try and investigate to the decision.The drugs purchase problem solved a hospital with DSS includes it certain social meaning and academic value. Say for the hospital:1.The drugs purchase that can solve a hospital to exist currently problem raises the science and time limited efficacy of drugs purchase decision in hospital and make decision maker can in time, rapid, availably carry on a medicine purchase.2.Make the management of hospital scientific, raise management level.3.Make the fluxion funds reasonable allocation of hospital, efficiently make use of.4.Raise the whole economic efficiency of hospital, make the hospital obtained the biggest economic income.At academic up:1.DSS is the heat of the calculator science and technology realm research to order of a, DSSPM research and development is as to it's theoretical fulfillment and application.2.Embodied DSS actual application value, opened widely a DSS application, for DSS of developed to do to contribute further and forward.Many after half year of make great effort work, the need having already basically bought according to drugs in the hospital completes to buy decision to support system to the drugs of initial design. In this time in, complete of main work have:1.Thorough studied decision to support system of theories knowledge, designed a drugs purchase decision support system of frame structure. That system adopts the frame structure of classic" three parts decision support system form, then includes a database system, model database system and others' machine's handing over system is with each other these three statures systems.2.That system set out from the angle of concrete application, the choice data warehouse was a data to organize a technique and pass to totally connect to come to concrete operation data within warehouse with the data. And buy the development trend of drugs purchase business in hospital inside need and future a period of time of making policy the analysis according to the drugs, divided the line a grain degree, made sure topic and carried on a concept model design, the first step completed the design of data warehouse in DSSPM.3.Designed a drugs purchase the decision supports system of the system structure , while carrying out the model in the model database, pass to totally connect a people data within operation data warehouse with the data and provide decision support for drugs management in the hospital.4.Need and future that buys to make policy analysis according to the drugs a period of time inside drugs in the hospital purchase business of development trend, divided the line a grain to the drugs purchase decision support system data warehouse degree, made sure topic and carried on a concept model design, and get the data of circulating the model.5.The adoption faced to the way of object to construct model and passed the design that model carried out a model database.See model set against elephant, among them, the data area of object is used to the appearance of describing the model and operated an area to then reflect the behavior of model.The mechanism of passing the inheritting of type carried out inheritting of model, many Tais of type worked out the conjunction problem of of model and passed to establish object to carry out the management to the model and control, with completion functions, such as model and movement model...etc..6.Pass the detailed survey to circulate the business to drugs in the hospital, built up three radicle models in DSSPM.Make use of these three models to predict the drugs sale quantity of one period in hospital, the first step carried out decision support to the hospital drugs purchase.7.Scoop out a data, the medium heredity calculate way applies in drugs purchase the decision supports system of in the model database system, carried out model to automatically choose of function, raised the intelligence of system.First step circulate enunciation, project design reasonable, calculate way credibility, predict result more accurate, can satisfy the request of drugs in the hospital purchase management, the first step carried out decision support to buy the management to drugs in the hospital. |
