Two-stage Malmquist Productivity Index with Intermediate Products

Different processes in Decision Making Unit (DMU) are the same as subprocesses in that DMU when it is not considered as blackbox. Most of the time these subprocesses are mooted in a series structure and frequently used in real world applications. When it is aimed to evaluate the performance of a unit with its subprocesses and what it did in the past, those techniques which show progress and regress can be used. One of these famous techniques is Malmquisr Productivity Index (MPI). Here MPI is developed and used for series structural DMUs, with two components, in which intermediate inputs and outputs exist.
