In this paper,the problem of distributing a constant amount of one inputamong DMUs, such that the efficiency of the whole system improves. we have appliedPnj=11MPIj (t1,t2) as an index of system’s improvement.Towards this end, we are supposed to solve a Parametric LP. Since havingparameter j in the technology matrix of a LP is not desirable, we used anon-radial model to evaluate DMUs’ efficiency measure which leads to aParametric LP that have j as a parameter in its RHS, and we applieda method based on interpolation to obtain the optimal solution of ParametricLP as a function of its parameter
