Figure A2
The horizontal axis is labeled with percentage values ranging from 0 percent to 100 percent in increments of 20 percent. The vertical axis is labeled with criteria listed from top to bottom as follows: “Cost”, “Applicability”, “Capacity”, “Time”, “Reach”, “Item condition”, “Policies”, “Infrastructure”, “Public acceptance”, “Safety”, “Privacy”, and “Environment”. Each criterion is represented by a single horizontal stacked bar extending from left to right, with different colors showing various research approaches. The legend at the bottom indicates the color codes used: blue for “Modeling”, orange for “Mixed”, gray for “Review”, yellow for “Survey”, blue for “Experiment”, green for “Conceptual”, and dark blue for “Case study”. The data for the bars on the graph are as follows: Cost: Modeling: 63.59 percent; Mixed: 24.87 percent; Review: 3.88 percent; Survey: 0.87 percent; Experiment: 3.39 percent; Conceptual: 1.90 percent; Case study: 1.50 percent. Applicability: Modeling: 66.89 percent; Mixed: 26.46 percent; Review: 2.85 percent; Survey: 0.60 percent; Experiment: 1.70 percent; Conceptual: 0.89 percent; Case study: 0.61 percent.

Time: Modeling: 61.43 percent; Mixed: 23.97 percent; Review: 2.63 percent; Survey: 1.67 percent; Experiment: 5.60 percent; Conceptual: 0.50 percent; Case study: 4.20 percent. Reach: Modeling: 47.90 percent; Mixed: 28.05 percent; Review: 4.85 percent; Survey: 4.21 percent; Experiment: 6.59 percent; Conceptual: 4.10 percent; Case study: 4.30 percent.
