Abstract This paper studies the efficiency assessment of Decision Making Units (DMUs) when their inputs and outputs are fuzzy sets. An axiomatic derivation production possibility set is presented a enhanced Russell graph measure formulated using arithmetic approach. The proposed approach uses polygonal sets LU-fuzzy partial orders, provides crisp measures (and associated ranking) as well effici...

Measures, especially efficiency measures, are crucial and pivotal in determining a company's performance level financial health, as well the extent to which they reflected other indicators. This study investigates company’s measure (working capital) contributes achieving returns for period 2009-2018. Therefore, it assumes that does not contribute cumulative abnormal return. drew several finding...
