THE JUST-IN-TIME INVENTORY EFFECT: DOES IT HOLD UNDER DIFFERENT CONTEXTURAL, ENVIRONMENTAL AND ORGANIZATIONAL CONDITIONS?
研究显示，随着准时制采购、生产和销售比例提高，库存周数从五六周降至不到两周，且该负相关关系在不同情境、环境和组织条件下普遍成立。
When the percentage of purchases, production and sales made on a just-in-time (JIT) basis increases, weeks of inventory decrease. This study demonstrates the nature of this inverse relationship in a wide variety of conditions that differ in contextural, environmental and organizational factors. On average, inventory is cut from between five to six weeks to less than two weeks as the JIT percentage goes from zero to one hundred.
