چکیده
|
In this paper, we consider the problem of evaluating the efficiency of a company, dmu, initially having sub-units, dmsu, for fulfilling their requirements in these internal subunits. this is similar to the methods of producing different items in a chain system, in which all the parts are provided in other related sections of the chain system. in fact, the output of every sub-unit in this system produces the internal input for the following subunits in the chain. we demonstrate the efficiency of all sub-units and finally the aggregate efficiency of them at large.
