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.
