Abstract: To describe decision models and related modules，a synthetical framework，composed of model representation，solver representation，data representation and related ontology base，is proposed.The framework is based on necessary extensions to OWL-S（Web Ontology Language for Service）.It has full compatibility with internet and semantic Web technologies，wide range of applications and convenience of communications among users.What’s more，the cooperation of model，solver and data services will benefit from the special designed data parameter in the framework.An example of a construction site layout problem is introduced to illustrate the description of the decision model using the proposed framework.And the example emphasizes on the description of the data parameter of the problem and the structure of the model.

Key words: decision model, representation framework, Web Ontology Language for Service（OWL-S）

摘要： 通过对OWL-S（Web Ontology Language for Service）进行必要的扩展，提出了包括模型表示、解程序表示、数据表示和相关本体库在内的综合表示框架来表示决策模型及其相关组件。该表示框架具有充分兼容网络和语义Web技术，适用范围广，易于用户交流，数据参数的设计考虑全面且有利于模型、解程序和数据的匹配等优点。以施工现场设施布置问题为例，说明了表示框架对模型的表示，重点对数据参数和模型内部结构的表示进行了描述。
