现有库存(on-hand inventory),库存水平(inventory level),库存位置(inventory position)

库存管理中,这几个名词特别容易混,干脆写一篇博客总结下。

  • 现有库存(on-hand inventory),是指持有的真实库存量

  • 库存水平(inventory level),现有库存减去延迟交付的订单
    inventory level = on-hand inventory − backorder quantity \text{inventory level} = \text{on-hand inventory} - \text{backorder quantity} inventory level=on-hand inventory−backorder quantity

  • 库存位置(inventory position),等于库存水平加上在途库存(已经下单但还没有到达的订单)

inventory position = inventory level + on-order quantity \text{inventory position} = \text{inventory level} + \text{on-order quantity} inventory position=inventory level+on-order quantity
