【摘要】 模型是决策支持系统的核心,为支持Web环境中决策问题求解和基于模型驱动的决策支持系统构建,在详细分析了Web环境下系统中各种决策实体及其相互关系的基础上,提出了一种基于Web的模型驱动决策支持系统描述框架,该框架采用可扩展标记语言进行一致性描述和以Web服务方式为用户提供统一接口调用。最后用导弹采办技术风险决策实例说明该框架的合理性和适用性。更多还原

【Abstract】 Model is the core of decision support system.To support decision-making problem solving and construction of model-driven decision support system(MDDSS)in the web environment,the paper demonstrates the decision-making entities and their relationship in the DSS of web environment.Then a description framework of web-based model-driven decision support system(WMDDSS)is introduced.The framework uses extensible markup language(XML)to implement expression consistency of decision model.In addition,it provides a unified approach of user interface calling with web services.Finally,an example of missile technology risk decision-making is illustrated to show the rationality and practicality of the description framework.更多还原
