چکیده مقاله :
In this paper, the cost and income efficiency models have been considered withregard to the multiple objective programming structures. For finding the efficientpoints in purposed MOLP problem, some various methods like Lexicography &the weighted sum can be used. So by introducing the MOLP problem the cost &income efficiencies will be achieved. In the present study, the MOLP problem isconverted to an objective function by the weighted sum of the objective function.So we determine the efficient hyperplanes gradient by finding the dual linearprogramming (LP) problem.
