A large number of algorithms have been proposed in the literature, which differ from each other based on the type of institution involved and the type of constraints. This paper first surveys the origin and the techniques, then presents the AI Planning-based algorithm to solve TTP. We implement the algorithm by SQL language, which is Timetabling Problem, and show that it is of great value by using the simulated data on it. At the end of this paper we describe other applied domains and its prospect.

时间表问题是一类应用非常广泛的研究课题，目前业出现了各种各样的解决时间表问题的方法，本文简要分析了近几十年时间表问题研究的历史和技术现状，提出了基于智能规划方法的时间表问题解决方案Plan TTP，并且我们用SQL语言实现了这一解决方案Plan TTP，通过对学校课程表的模拟实验证明该方法具有较大的使用价值，最后指出Plan TTPS的一些其他应用领域和发展前景等。

From the perspective of theoretical research, the extreme orientation of both philosophy and psychology will lead to the contradiction and breaking of knowledge teaching and students' development. Consequently, the development of all the students to be human being would be lost. From the perspective of teaching practice, both the spoon-fed teaching and experience-constructive teaching, either controlling or indulging students, as a matter of fact, lead to the lost of cultivating students to be human being. Analyzing from the perspective of ideology, Herbart's "educational teaching", Dewey's "experience" curriculum and teaching ideology and constructivism make contributions to knowledge teaching. However, they have, constraints. If we cannot understand both their advantages and disadvantages but simply support or deny them, teaching research and practice will go to an extreme.
