Abstract

Abstract: In order to meet the need of representation and reasoning of uncertain temporal knowledge, uncertain temporal relationship is extended into strong relevant logic. Some relevant concepts of rough sets and strong relevant logic are given; strong relevant logic is extended to form rough temporal strong relevant logic by defining uncertain temporal relation, and the prove of its reliability and completeness are given; representation and application of uncertain knowledge based on the rough temporal strong relevant logic are validated using a practical example. The result shows that it is easy to represent uncertain temporal knowledge using the extended rough strong relevant logic.

Key words: uncertainty temporal, strong relevant logic, rough sets, representation of knowledge, emergency

摘要： 在强相关逻辑基础上扩展不精确时态关系，以满足不精确应急时态知识表示与推理的需要。给出了粗糙集及强相关逻辑的相关概念；通过定义不精确时态关系扩展了强相关逻辑，形成了粗糙时态强相关逻辑，给出了可靠性和完备性证明；通过实际例子说明粗糙时态强相关逻辑的知识表示和应用。结果表明扩展后的粗糙时态强相关逻辑可以实现不精确时态知识的表示与推理。
