Figure 2
The figure shows a five-step framework for analysing humanitarian material donation systems. Step 1 involves selecting the Luding earthquake case and defining a 29-day emergency period. Step 2 covers data preparation from official donation records, cleaning, and standardisation to obtain 1,287 valid entries. Step 3 defines an indicator system categorising donation input, output, and environment. Step 4 applies an entropy-based model to compute correlation and running entropy values. Step 5 assesses system orderliness and compares four donor groups, including government, enterprises, organisations, and individuals. The flowchart connects these steps sequentially with arrows, showing data flow between preparation, analysis, and evaluation.Research framework for evaluating orderliness in the HMDS
