On Inventory Abatement via Manufacturing Randomness Reductions*
研究在持续改进框架下，通过减少制造随机性来降低库存的策略，发现减少随机性不一定降低库存，有时反而增加库存，但能提高客户服务水平。
ABSTRACT Under a continuous improvement framework, the policy of abating inventory via reductions in manufacturing randomness is considered. To explore this policy, a model of a real‐world production‐inventory system is developed, tested, and studied. The results suggest that manufacturing randomness reductions, even substantial ones, may not necessarily lead to inventory abatement, and paradoxically may lead sometimes to an inventory increase. In these cases, however, manufacturing randomness reductions will translate into higher customer service levels.
