The main purpose of the paper is to generalize the concept of equitable efficiency by introducing the concept of equitable A-efficiency, where A is an arbitrary matrix with non-negative entries. Two conditions are provided to ensure that the relation of equitable A-dominance is an equitable rational preference relation. Furthermore the structure of equitably A-efficient set is investigated and is proved that the set of equitably A-efficient solutions is contained within the set of efficient. Hence to reduce Pareto-optimal solutions, we can use equitably A-efficient solutions.
