Fig. 4. Measured correlations between the adjusted and raw utilizations of successive blocks. The average adjusted and raw OR utilizations are the independent variables in the computer simulations. They are plotted on the vertical axis, as in Figs. 1–3. “Adjusted” and “Raw” in the figure identify curves for adjusted utilization and raw utilization, respectively. Auto-correlations are plotted on the horizontal axis. The figure shows that the correlations between utilizations of successive OR blocks are correlated.
