中文摘要：

针对开放式环境对松散耦合的灵活协作模式的需要，以及协同设计问题通常具有的“结构不良”和“创新参与”的特性，提出RPACTI Agent模型．该模型拓展了传统的确定性协作接口模式，加入了非确定性的接口描述和调用方式，提出了基于能力、潜力和兴趣的三接口模式，并在此基础上提供确定性、尝试性和弱约束集成的混合协作模式，以更加灵活的方式处理协同设计问题．同时，在模型中引入基于政策的管理，以保证自组织协作过程是面向需求和可控的．该模型既考虑了解决问题的成功率和效率，又体现了灵活性，更加适合开放式环境下的协同设计问题．

英文摘要：

Aiming at the requirement of flexible cooperation mode in open environment, and the ＂ill-structured＂ and ＂creativity-needed＂ characteristics of cooperative design problem, this paper presents an RPAcTI Agent model. This model extends traditional modes that only have determinate cooperation interfaces, by adding indeterminate interface description and invoking methods. It is proposed a new mode based on three kinds of interfaces： capability, potentiality and interest. Furthermore, the model supports a hybrid mode of determinate, tentative and weakly-constrained collaboration, enabling agents to cope with dynamic and uncertain problems in a more flexible manner. Policy-based management is also integrated into the model, ensuring that the self-organizing collaboration is demand-oriented and controllable. The model is competent for solving the cooperative design problems in open environment because of its success rate, efficiency and flexibility.
