| Abstract: | This paper presents an unified model which can represent qualitative and quantitative temporal information as well as certain and uncertain temporal information. After defining the time points and the time intervals,we define the relations among time points and the relations among time intervals and discuss the composition of the relations. Then we discuss the reasoning problem and give two examples. |
