AN APPLICATION OF DATA ENVELOPMENT ANALYTIC NETWORK PROCESS (DEANP) IN QUALITY FUNCTION DEPLOYMENT (QFD)

In this paper a solution method is proposed for emphasizing the importance of costumer needs at the starting of quality function deployment (qfd) application when there are multi costumer groups. data envelopment analysis (dea) steps are added to an algorithm in which an analytic network process (anp) approach is used in qfd. the need for adding dea steps is determining the efficient customer requirements when there are multi customer groups. this solution approach is called deanp which aggregates data dea to anp. the relative importance values of product technical requirements are calculated with this algorithm and application is performed at a manufacturer of white goods company in turkey. the fact that using deanp instead of anp produced more powerful solutions is also confirmed by marketing specialists.
