Designing a Mathematical Screening Model to Select the Key Problems in (EFQM) Excellence Model

We can call “EFQM excellence model” as a transition from the great number of different models and approaches to unity in context of organizational improvement and excellence. Doing self-assessment to find areas for improvement (AFIs) is the most important application of this model. Those organizations which are on lower level of total quality management will encounter lots of AFIs. So finding key problems is an important challenge for them. Reviewing the literature shows that there is no specific and systematic model to solve this challenge. We intended to introduce a mathematical screening model in order to help organizations to find their key problems. The proposed model was designed in fuzzy context, because decision making situation of most of the organizations is in vague and ambiguity.
