A distribution-driven simulation ma

A distribution-driven simulation may be inaccurate, however, because of relationships between successive events in the real system.
The frequency distribution indicates only how many instances of each event occur; it does not indicate anything about the order of their occurrence.
To correct this problem, we can use trace tapes.
We create a trace tape by monitoring the real system and recording the sequence of actual events (Figure 6.25).
We then use this sequence to drive the simulation.
Trace tapes provide an excellent way to compare two algorithms on exactly the same set of real inputs. This method can produce accurate results for its inputs.
