Context-aware pervasive computing application system should be flexibly adaptable to dynamic changes of context and application requirements and proactively provide the information satisfied with current context for users. The concept model and developing approach based on preference model presented by (K. Henricksen and J. Indulska, 2004) can satisfy the adaptation of context-aware pervasive computing application in a certain extent. However, this model can't easily describe fuzzy fact. Moreover, codes need be modified when constraints on system behavior have changed. Based on their production, this paper presents one type of rule, expresses fuzzy fact using operator predicate logic and presents a developing approach based on this type of rule. Therefore, the context-aware pervasive computing system developed using this approach need not modify codes when constraints on system behavior have changed. Such system can be more adaptive to dynamic changes and proactively provide information. In addition, requirements of context-aware pervasive computing application system can be expressed more accurately. Finally, experiments and examples prove that the model and approach proposed are feasible
