Figure 7
The diagram is a two-dimensional plot titled “Feasible Range of Fixed Investment (F subscript k) (considering consumer congestion).” The horizontal axis is labeled “Sensitivity to quality inconsistency, delta” and ranges from 0.00 to 0.35 with an interval of 0.05. The vertical axis is labeled “Fixed cost for central kitchen, F subscript k” and spans from 0.00 to 0.05 with an interval of 0.01. The legend in the top left provides labels for the blue curve and both shaded regions. The blue curve is labeled “k of (delta),” the pink region is labeled “Partial Market Coverage for Main Model,” and the yellow region is labeled “Full Market Coverage for Main Model.” A blue upward-sloping curve represents a function that starts from the origin and rises smoothly in a concave-upward trend, which ends at the top right. Two vertical dashed lines divide the horizontal axis into three regions: a green dashed line at around 0.10 and a purple dashed line at around 0.15. Between these two lines, the area under the curve is shaded in pink. To the right of the purple dashed line and left of the green line, the area under the curve is shaded in yellow. Note: All numerical data values are approximated.Feasibility of central kitchen adoption: threshold analysis of (κ(δ)). Source: Authors’ own work
