Abstract :
In this paper, we consider a three-stage network comprised of a leader and two
followers in respect to the additional desirable and undesirable inputs and
outputs. We utilize the non-cooperative approach multiplicative model to
measure the efficiency of the overall system and the performances of decisionmaking
units (DMUs) from both, the optimistic and pessimistic views.
Moreover, we utilize the concept of a goal programming and define a kind of
cooperation between the leader and followers, so that the objectives of the
managers are capable of being inserted in the models. In actual fact, a kind of
collaboration is considered in a non-cooperative game. The non-cooperative
models from this view cannot be converted into linear models. Therefore, a
heuristic method is proposed to convert the nonlinear models into linear models.
After obtaining the efficiencies based on the double-frontier view, the DMUs
are ranked and classified into three clusters by the k-means algorithm. Finally,
this paper considers a genuine world example, in relevance to production
planning and inventory control, for model application and analyzes it from the
double-frontier view. The proposed models are simulations of a factory in a real
world, with a production area as leader and a warehouse and a delivery point as
two followers. This factory has been regarded as a dynamic network with a time
period of 24 intervals.
