针对移动社交网络下随机型群体需求形成的内部机理研究的不足，基于群体需求感知、资源及偏好等状态信息，给出了可实现资源有效利用的移动社交网络下随机型群体需求的识别方法。根据个体具有的需求信息及满足需求所拥有的资源条件，将需求状态划分为：显性状态、资源型隐性状态、感知型隐性状态和完全隐性状态，给出不同状态之间的转换机制。基于此分析了移动社交网络下随机型群体成员动态变化对群体需求状态的影响机理，结合群体偏好状态信息，识别出可实现群体资源实时最优配置的群体需求。最后结合实例验证了该方法的有效性。

For inadequate research on the internal formation mechanism of random group requirements in mobile social network, this paper analyzes the identification progress of random group requirements based on their shared resources and information of group requirements. According to the perception of the requirements and resources of the individuals, we analyze the internal structure of requirements and divide them into four states: state of feasibility, state of unfeasibility with lack of resource, state of unfeasibility with lack of awareness and state of complete unfeasibility. The mechanisms of transition between different states are described. Based on this, this paper analyzes the influence mechanism of random group members忆dynamic changes on group requirements in mobile social networks, and identifies the group requirement that can realize the real-time optimal allocation of group resources. Finally, an example is given to verify the effectiveness of this method.
