The flow diagram begins at the top, labeled “Selected criteria”. A downward arrow splits into two branches, each leading to two rectangles placed side by side. The left rectangle is labeled “Measurable criteria”, and the right rectangle is labeled “Forecastable criteria”. From the left rectangle, a downward arrow moves into an oval labelled “Historical and new suppliers”, which connects to a wide rectangular box labelled “S subscript nk”. Inside this box, two smaller adjacent rectangles appear; the left is labeled “Cost criteria (inverse normalization)” and the right is labeled “Benefit criteria (direct normalization)”. On the right, “Forecastable criteria” branches into two downward arrows. The first arrow leads into an oval labelled “Historical suppliers”. The second arrow leads into another oval labelled “New suppliers”, followed directly below by a small rectangle labelled “Scenario-based approach”. Both the “Historical suppliers” oval and the “Scenario-based approach” rectangle connect downward to another wide rectangle labelled “S subscript nkm”. This rectangle also contains two adjacent internal rectangles; the left reads “Cost criteria (inverse normalization)” and the right reads “Benefit criteria (direct normalization)”.Framework of the suppliers’ scoring processes.
