Simulation details for step 1
| Regions | Based on a total of 12.6 M units annually * | Standard deviation of supply (4 variations) | A blood donor shortage imposed Three main scenarios: A, B and C |
|---|---|---|---|
| Region 1 | D1 = 30% (Dt) S1 = 25% (St) | 5% 7.5% 10% 12.5% | Scenario A: No shortage Scenario B: No shortage Scenario C: 50% of blood donors are eliminated for 4 weeks |
| Region 2 | D2 = 25% (Dt) S2 = 25% (St) | 5% 7.5% 10% 12.5% | Scenario A: No shortage Scenario B: No shortage Scenario C: No shortage |
| Region 3 | D3 = 20% (Dt) S3 = 25% (St) | 5% 7.5% 10% 12.5% | Scenario A: No shortage Scenario B: 50% of blood donors are eliminated for 4 weeks Scenario C: No shortage |
| Region 4 | D4 = 25% (Dt) S4 = 25% (St) | 5% 7.5% 10% 12.5% | Scenario A: No shortage Scenario B: No shortage Scenario C: No shortage |

Note(s): * Demand is normally distributed. The unit of annual demands is recorded from the American Red Cross (www.Redcross.Org) and BCA websites. Units of supply are assumed to match the annual demand. Total demand (Dt) = D1 + D2 + D3 + D4 and total supply (St) = S1 + S2 + S3 + S4
