Abstract: Rough set theory is a mathematics tool specifying imperfection and uncertainty. Based on the knowledge theory of the rough set, the numerical values of some features or attributes are not required. Through data reduction, this article analyzes the investment decision of hydraulic engineering and obtains the following by reduction: i. when the construction expense of the hydraulic engineering is low, but the financial income is high, the investment in the construction project can be selected; ii. when the expense of the hydraulic construction project is low and the external influence is common or the financial expense is common, if the external influence is low or the financial income is high, the investment can be delayed; iii. when the construction strategic benefit of the hydraulic engineering is low, the decision rule of no investment can be selected. The novel findings discovered by this article have provided scientific information regarding investment decisions of hydraulic engineering.
