DSS中广义模型服务器规范化研究与实现

DEVELOPMENT AND DESIGN OF GENERIC MODELS SERVERS STANDARDIZATION IN DSS

DSS是由大量广义模型 (多种类型的模型 )有机组合而成的 .采用客户 /服务器方式设计与实现广义模型服务器是一种新的方法 .为了有效的实现广义模型的管理、组合和运行 ,服务器的规范化成为 DSS的重要问题 ,包括广义模型规范化 ,服务器体系结构规范化 ,模型调用、运行、操作语言规范化等 ,本文通过分析广义模型的种类和表达方式 ,给出通用的模型规范化设计和实现方案 ,在此基础上提出一种层次化模型服务器规范设计方法 .包括定义了单模型和组合模型数据描述文件的格式、模型规范化封装类层次结构 ,服务器各层次功能划分等 ,最后给出一应用实例 .其中模型操作语言规范化由其它文章论述 .

DSS involve many kinds of generic models . It is a new method to develop models server by using the mode of client/server . The standardization of models server plays very important part in managing, combining, running models efficiently , which include the standardization of a wide range of models , the standardization of the structure of models server ,the standardization of MML(Model Managing Language) and so on . In this paper, through analyzing all kinds of models , we proposa general solution to development and design of the standardization of models , then present a standardization of models server based on it. The contens of paper include defining data description file structure of models, the hierarchy of model class encapsulation , the function of layers in models server etc. At last, an instance is given to illustrate that the method is available and effective.
