主机厂零部件JIT供应物流规划与应用

JIT Inbound Logistics Planning of Auto Parts for Whole Vehicle Manufacturer

为了解决主机厂供应物流交付不及时、卸货位忙闲不均、物流费用不透明、运输效率和服务水平低、管理不可控的现状问题,应用"5W3H"和问卷调查法提出了A车型发动机和变速箱供应物流采用取货制的解决方法。建立了基于平准化、准时化的物流和信息流模型,基于三流合一建立了物流、信息流和资金流作业流程。通过规划方案在试点改善中的应用,使配送中心库存由10 d降为3 d,运输车辆由16台减为8台,每年降低运输费用1 000万元。结果表明该研究成果对于企业提升物流管理水平、降低供应链物流成本和增强整体竞争力具有指导作用。

In some whole vehicle manufacturers, there are problems in part supply, such as late inbound delivery, unevenly busy or idle in port unloading, non-transparent logistics cost, low transportation effi- ciency and service level, uncontrollable management, and so on. To solve this problem, by using ＇5W3H＇ and questionnaire survey, a study is conducted for engine and transmission production of A-type car in a whole vehicle manufacturer. Then, with Milk-run system, solution is presented for the problem. Thus, based on the concept of equalization and just-in-time （JIT）, logistics and information flows are es- tablished. Further, based on the idea of integrating three flows into one, information flow, cash flow, and operation process are also established. Result shows that, for typical large parts, the inventory in distribu- tion center has been reduced from 10 days to three days, and transport vehicle quantity has been reduced from 16 to 8, and it saves transportation cost 10 million Yuans per year. This is a significant improvement.
