This paper presents a conceptual design decision making approach through operational modeling through the eyes of the airline. It put more emphasis on the engine maintenance, repair and overhaul, since engine maintenance is about 13% of the total cash cost. A key element of the research is a simulation program through Operation Simulation Modelling OSM, that has been built by the others to create an operational modelling environment to see the impact of different design technologies, or concepts, or compare different type of engines operation on a real environment through the eyes of the customer (i.e. the airline engineers and mechanics). The Rolls Royce engine (RB211-524D4) for a specific airline has been chosen to be the case study and validate the code in case of man-hours. Finally, it was found that OSM givens outcome for the baseline maintenance hours, and man hours needed give an difference 2.7% and 0.8% respectively.
