optimal resource allocation in dea with integer variables

resource allocation and optimal leveling are among the top challenges in project management. this paper presents a dea-based procedure for determining an optimal level of inputs to produce a fixed level of outputs. to achieve this goal, we assume that the levels of outputs can be forecasted in the next season and the procedure will determine optimal level of inputs for all dmus. such as some of them can only take integer values. so, after this design for the value of inputs and outputs all dmus are placed on the optimal level. an illustrative example is used to show the applicability of the proposed method.
