考虑orness测度水平为不确定型的情况下如何求解MEOWA算子权向量问题。结果表明：不确定型orness测度下求解MEOWA算子权向量可以转化为相应orness测度区间端点或内点时的MEOWA权向量的求解,并对两者的关系进行分析。将该方法应用于某化工建设项目环境影响技术评估,算例表明该方法的可行性和有效性。

英文摘要：

A method for solving the weight variable of the maximal entropy ordered weighted averaging （MEOWA） operator is proposed, based on the uncertainty of orness measure. Our analysis shows that the problem can be solved by transforming it into a problem of the weight variable of the MEOWA under the corresponding endpoints or interior point of interval of orness measure; the relationship between these two approaches is dis- cussed and analyzed. Finally, the new method is used in a technical assessment of the environmental effects of chemical plant construction, which highlights the feasibility and effectiveness of the method.
