Higher eef means lower operating cost. So, they are related indirectly.

Energy Efficiency Ratio or EEF is inversely related to the operating cost whereby increased EEF means decreased OC (operating cost).
Say for instance:
Energy efficiency ratio (EER) of ACs:  The ratio between the cooling capacity and the power input of the Air Conditioners (ACs) .

For instance, if a 1 TR (3500 W) AC consumes 1000 watts, then the EER of the Air Conditioners is 3.5 W/W.  Air Conditioners (ACs) with high EER consume less power.
