VSM을 약간 변형해서 만든 SCM 시뮬레이션 사례입니다. 고객의 구매에 대응하기 위한 적정 재고 레벨을 계획하기 위한 모델인데, 재고량이 없으면 판매기회를 상실한 것으로 판단합니다. 고객의 주문 확률, 이에 대응하기 위한 물품의 오더 주기 및 오더의 lot 수량, 각 단계별 프로세스의 처리 능력 등이 모델화 되어 수행됩니다. 시나리오에 따라서 고객의 service level 및 판매기회 상실 수량 그리고 Supply chain 내에서의 lead time과 평균재고량 등을 분석할 수 있으며 시나리오별 물류비와 판매이익을 분석하여 최적의사결정을 지원합니다.

''Using a Witness model forced us to challenge in detail the methodology of our proposed LEAN production process. The result was a change, not only in how we produce, but also how we control and measure production.'' John Laister SCM Process Manager

An advanced business simulation tool from Lanner has been used by Batchelors Foods (part of Campbell Grocery Products Ltd.) to ensure that a planned change to their supply chain would not be compromised by an adverse impact on inventory and customer service levels.
