问题 问答题

G公司是专业生产硬盘视频播放机的企业,其产品根据内置硬盘容量的大小,分别有120G,160G,250G几种规格。这些产品除硬盘容量不同以外,其他结构完全相同。
G公司制造模式是按照营销部门提出的销售预测,编制主生产计划,然后运行MRP,分解出物料需求计划,进行物料采购。生产出成品后,放在仓库中,接到客户订单后真接发货。
G公司生产线每天的产能很大,基本可以满足每天订单的需求量。其主要材料硬盘的供应商库存也比较大,在G公司下达采购硬盘订单后,2小时内可以到货。而其他部件,虽然交货周期长,但其价值相对较低,且各个型号通用。
因此,从下达硬盘采购订单到生产为成品,一般在一天以内,而G公司的客户对交货期的要求是下达订单的2日内发货即可。
根据以上案例提供的资料,请回答问题
1.请分析G公司的产品可能发生断货或者库存积压现象的原因是什么
2.G公司目前的存货缓冲点在哪?如果通过改变供应链上存货缓冲点的方法来改善库存问题,你建议可以把缓冲点移到哪一点?这两点之间的区划在哪里?
3.G公司准备按照你的建议,改变存货缓冲点,此时,G公司的销售、计划、生产、采购、物流部门应该做出哪些改变来保证新的生产方式顺利进行?

答案

参考答案:1.(1)销售预测不会是准确的,按照销售预测备货,必然出现产品冗余与不足;
2.(1)目前的DP点在DP2(按库存生产)。
(2)可以移动到DP3(按订单组装)。
(3)两者区别:
①DP2的库存形式是成品、DP3的库存形式是零件、部件。
②库存资金占用,DP2比DP3要大。
③交付时间,DP3比DP2要长
3.(1)销售部门还需要提供销售预测,并提高预测精度,并做好与其他部门的沟通。
(2)计划部门排定生产计划的时间要更短,并需要与供应商共享生产计划。
(3)采购部门应该做好让供应商JIT送货的相应准备。
(4)采购部门应和主要供应商保持更紧密的关系。
(5)生产计划的执行应比以前更严格,生产部门应在设备保障、生产质量上做出更多努力。
(6)物流部门应保证配货、发货过程更准确、时间更短。
