Figure 13.
The figure contains two graphs. Graph (a) on the left shows market share on the vertical axis ranging from 0 to 0.7408, plotted against time in months on the horizontal axis from 1 to 100. Four series are displayed: base run, accuracy control, stock control, and combined accuracy plus stock control. The base run and accuracy control series are relatively stable, while stock control and combined control show higher fluctuations, with noticeable sharp drops near months 28, 36, and 82. Graph (b) on the right presents cumulative market share error on the vertical axis ranging from 0 to 4.352, against the same time period. The base run and accuracy control lines rise steadily with lower error, while stock control shows greater increases in error over time. Combined accuracy plus stock control falls between the two patterns. Legends below the graphs identify all four scenarios. Overall, accuracy control shows the most stable performance, while stock control contributes the highest volatility and error accumulation.The realisation of market share under the improvement scenarios
