摘　　要：在医院门诊收费业务中,各执行科室有不同的计费规则且可能频繁变动,原系统硬编码的设计方式使系统维护工作繁重且有效维护越来越困难。为使门诊收费系统能灵活应对计费规则的新增、修改及启用禁用等需求,提出基于抽象工厂和责任链的门诊收费架构,并给出了有效的系统设计和实现方案。新的门诊收费系统不仅简化了门诊收费处理流程,且增强了程序的可扩展性,让系统易于维护和升级。In the outpatient charging business in hospital,different executive department may have their own charging rules and these rules may change frequently.The original charging system using the way of hard-coding,thus brings huge workload to system maintenance personnel and makes it more and more difficult for them to implement effective maintenance.In order to respond flexibly to the demands of adding,modifying,opening or closing charging rules in outpatient charging system,this paper brings out the abstract factory and responsibility chain based outpatient charging structure,then offers effective designs and plans for realization.The new system not only simplifies the process of charging,but also enhances the scalability of the program,and making it easy to execute system maintenance and upgrade.
