2.The complexity of various cost factors is reduced through application of Activity Based Costing(ABC) method. The benefits of low level activities, both tangible and intangible, are hierarchically aggregated into higher level activities.
3.Generally the events of interest are quite rare (many orders of magnitude slower than the vibrational movements of the atoms), and therefore direct simulations, tracking every movement of the atoms, would take thousands of years of computer calculations on the fastest present day computer before a single event of interest can be expected to occur, hence the name EON, which is an immeasurable period of time.
