參與討論知名ERP軟件的BOM, WorkCenter 及 Routing 結構!

暂时我还没有发现象上面所说的化学物品的情况，不过要是有，应该在批次和体积、重量上应该有所不同，不知道现在SAP、CA、SSA上有没有这样的设定。

Here's a specific question:

An electronic finished part has a component that can be wither purchased or made in house. The buy-or-make decision is made at the planning stage. How does SAP, Oracle, Baan or other systems handle this? (BOM structure, planning and scheduling, MRP, etc.)

Another good one:

a component in the BOM is purchased from a supplier then sent out for processing. Then received back and processed. The customer want to keep track of the purchased part and the part that is sent out. How to construct the BOM and how to track the status of the material, costs, and how to run MRP? This happening frequently in metal plating parts for eletronics manufacturing.

Would like to hear your solutions.

各行各業的特點﹐一早曾想過﹐集中各位的才智﹐歸納一下﹐但由于不少的網友都是在談市場﹐在談實施﹐還有什么概念新名詞之類的﹐有實際工廠經驗的少之又少﹐現在正在計划在我
自己的網站上﹐以BBS的方式記錄大家對行業生產的了解。

jameson_cn所說的建立一虛構件﹐這點還是很有意思的﹐雖然說這本來就是實在的東西﹐但也不償是一種解決方案﹐我覺得問題的關鍵是如何在BOM,WorkCenter。。。等之間﹐以什么邏輯實現它???

如huimao123所述﹐例子還是比較適當﹐在邏輯上是同一層的﹐但在工藝上卻不一樣

i think may be solution is following :
the first question's solution

in my practice , the PMC planner will decide to how many should to be purchase and how many should to be manufacturing . Lauch MRP after released the manufacturing quantity and the Purchasing quantity . another way , may be you should set up a substitute component , this component  existing in finished assembly . the attribute of component is purchased . this is ok !  the MRP will not have to run two again .

the second question's solution

i think you should creat a out resourcing Part number for this question of sent out for processing and add to new level in your BOM . then following the system's OSP workflow . the cost ,track and material control will no problem .

ok , that is all . by the way , my system is Oracle .

有关Woher 提出的问题：
1、可以通过既可以采购也可以制造来处理。在ORACLE中指明是制造还是采购方式，同时指定可以采购也可以制造，这样在MRP计划转换成定单时，可以分配生产多少和采购多少。这样只对子件的需求有影响。SAP中花有配额来管理生产多少和采购多少，各供应商供应多少的处理。
2、采用直接采购的方式处理

为什么没有人去讨论BAANI呢，它也是一个不错的ERP软件，对于它的物料清单及工艺流程还可以吧，并还有一个测试BOM是否有死循环，如上A物。　

lzlcn2001

对于BAAN中是不允许的，它是一个死循环，BAAN还有专门的一个程序去检测它。但对于化工行业真的有这种情况，A的生产可能以A作为一个媒体，经过化学反应产生更多的成品A。这样SAP，ORACLE可以处理吗？好像现在的ERP的软件，难于在化工行业中实施对吗？

jameson_cn

上面已经给大家说过可以递归处理BOM，在SAP中可以设置。当然通过设置识别不让递归件做死循环就可以了。实际情况不就是这样吗，不管是回流还是回用。

在qad的系統中有一個關聯產品的bom。當需生產其中一個產品時，系統會自動生成另一個產品的工作單。

看见大家讨论的都很热烈，我也来提一个问题。以前做工艺的时候经常碰到这样的问题： 一个部件“轴” 由 “轴芯”，“轴套” 和 “销” 装配而成， 轴芯 共有 6道工序，轴套有8套工序， 其中 轴芯 的第5道和轴套的第7道需一起做（装在一起，钻销孔，我们称之为 配作，在普通的机加工中这种情形很常见，但精度高的加工设备不需这么做），孔钻好后，再拆开，进行各自的后续工序。 对这样的加工情况，在ERP中排routing时应如何做，各位可有这方面的经验，望能与我交流。
