Figure 3

Left: The number of unused kits for each week. Right: An example of the consumption rate \(r^X_t\). These charts are for the representative medical institution belonging to group B, which is shown in Fig. 2. The green cross (\(\times \)) and dotted line stand for strategy \(S_1\), the yellow plus (\(+\)) and dash–dotted line for strategy \(S_2\), the blue bullet (\(\bullet \)) and solid line for strategy M, and the red square (\(\blacksquare \)) and dashed line for strategy I (note that this should be constant in theory, but it is not and increases due to the truncation effect).
