In this thesis, we have proposed the algorithms of performing of three improving types, can improve the efficiency of prospecting of the unusual fluctuation database , so the improvement type of a thesis performs algorithms and will not need to rescan the whole database each time when there are newly-increased materials, the majority only needs to scan the newly-increased trade materials, in order to improve the efficiency of prospecting.

在本论文中，我们提出了三个改良式的演算法，第一个为Apriori演算法来动态探勘，其二为使用布林演算法为基础进行动态探勘，最后为以布林运算为基础之FP-tree的动态探勘，可以提升异动资料库的探勘效率，因为在过去的资料探勘技术中，在探勘关联规则的过程中，若有新增或删除交易资料时，则必须重新计算一次，将造成前次探勘计算的重复及资源的浪费，所以本论文的改良式演算法当有新增资料时将不用每次都要重新扫描整个资料库，绝大部分只需要扫描新增的交易资料，以提升探勘效率。

Through the comparison of different conditions in multi-angle repeated test, we observe the disaccording path of risk preferences. The main content of this thesis are as follows. Firstly, we design 2 sessions of experiments to find the impact of the softening budget constraint and the form of endowment on the risk preference. Besides, this thesis also includes several experimental comparative studies, focusing on the dynamical inconsistency of risk preference as well as its drifting path.

It also eliminates the invalid paths between statuses considering the restriction of minimum continuous time of on and off , and tamps rates , thereby reducing the number of paths in dynamic programming and attaining the aim of reducing dimensions . After confirming the running or suspended status of units , the approach is used to distribute powers among units , thereby increasing the efficiency of dynamic programming greatly .

通过比较各时段负荷及机组参数，剔除各时段下不满足要求的组合状态，从而减少动态规划中的状态点数；根据机组的最小连续运行，停运时间限制，计及机组功率上升，下降速度的约束，剔除了状态点间的无效路径，从而减少了动态规划的路径个数，达到降维的目的；在确定机组启停状态后，再采用解析法进行机组的功率分配，可以大大提高动态规划方法的效率。
