Abstract: Context-aware computing is one of key problems of intelligent environment and the context-aware application has focused on providing services to users.Context-conflict often occurs when multiple users share limited resources at the same time in intelligent environment.The mathematical model of context-conflict is built based on fuzzy set and systematology.The context-conflict resolution policy is represented as finding the extremum of a constrained multivariable function.In desirable scenarios，this resolution policy can describe the context-conflict problem concisely and serve users without distracting or sacrificing others.This proposal for solving context-conflict situations simplifies development of context-aware applications.

Key words: ubiquitous/pervasive computing, intelligent environment, context-aware, context-conflict

摘要： 情景感知是智能空间中的关键技术，是用户在智能空间中获得服务的依据。由于智能空间中提供服务的资源是有限的，多个用户在同一时间内争夺资源服务时，就造成了情景冲突。根据模糊集和系统学，建立了情景冲突的数学模型，并将解决情景冲突问题可转化为一个多元函数求条件极值的问题。实例分析表明，这个方法能简明地描述情景冲突问题，并能有效协调解决情景冲突。这方法具有较好的描述情景冲突能力，适合于在计算机实现。
