Is the Risk Pooling Strategy applicable in all circumstances? 1. 수요의 변동계수 (Coefficient of Variation)가 높으면 높을수록 Risk Pooling을 도입했을 때의 Benefit은 더 커짐. WHY? 변동계수 = 표준편차 / 평균 & 평균재고 = 안전재고( z) + Q/2 2. If demands are positively correlated, the Benefit from Risk Pooling disappears. WHY? + - + + - - - + + + - 15
