Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  discusses parametric solutions and envelopment formulations of radial data envelopment analysis (DEA) models with mixed orientation of input and output. These solutions geometrically but not numerically lie beten the two usual solutions from input and output orientations. The consequent results provide alternative optimal solutions beten those from input- and output oriented CCR models for constant returns to scale DEA models and optimal scale efficiency in addition to technical efficient solutions from input- and output-oriented BCC models for variable returns to scale DEA models.
