摘要：

In this paper, comparisons of OWA operators and ordinal OWA operators are carried out by using lattice theoretic methods. It is proved first that in both cases, the set of all aggregation operators forms a lattice, then the concept of positive valuation is used to measure the ''orness'' of aggregation operators and the structures of all such possible ''orness'' measures are determined.
