【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.更多还原
