Manufacturing Washers from Pipes

[rhowell]

HI All,

I'm looking for a way to use the MRP to create a load of washers from a
length of steel pipe which is ordered in from a supplier. A piece of pipe
is cut into 1000 pieces so one productId is chopped up and 1000 items of a
different productId needs to be put into stock and a number of these
washers used further down the production chain.

Assembling the length of pipe from 1000 washers is straight forward enough
- but I need to effectively disassemble the pipe and I cannot see if this
functionality has been implemented. Can anyone point me in the right
direction?

Many Thanks,

Hi Rupert,

I'm far from a MRP expert, but AFAIK this does not exist in OFBiz OOTB. This would be a reverted (or inverted, also breeder) BOM. The only place I have seen something near so far in "OFBiz world" is in Opentaps. But IIRW it's only for returns of  MARKETING_PACKAGEs, which makes sense when you want to get all  pieces separated back to inventory.

I will soon maybe be in need of such a thing (food industry), and I'd love to have it in OFBiz OOTB. We could draw our inspiration from Opentaps and contribute it... We could even dream of a world which would use this new OFBiz feature in the (hopefully clean) recycling business...

I will need this functionality for a manufacturing company that disassembles assembled parts from past production runs.  Adding a new "Disassemble" routing task type could serve as a flag for performing an inverted BOM.  For my case, a new "Inverted BOM" Bom Type would probably need to be created to allow for production runs in both directions (assembly and disassemble).  I'll probably start working on this within a week.

Hi OFBizzer,

It would be nice if you could subscribe to the OFBiz MLs instead of only using the Nabble forum. I saw that you already posted interesting messages, like in this thread http://ofbiz.135035.n4.nabble.com/view-entity-complex-alias-bug-td4641422.html#d1369166965070-220

For the current subject, we could maybe ge in contact you, Rupert and I. At least sharing efforts through a Jira.

Rupert, would you mind create one for us?

TIA

Jacques

Hi Jacques

Jira for this has been created:

Hi Rupert,

The manufacturing processes you describe are included in standard OFBiz
functionality.

But, you are mixing terminology. What you describe (cutting up a length of
pipe into washers is not a discrete manufacturing process (assembling
components into a product), but a process-oriented manufacturing process.
Reversing the process by disassembling the product into its components is
possible in discrete manufacturing, but reversing the process is not
possble in process-oriented manufacturing. The best example is the the
scrambled egg paradigm. You need to beat (the process) the egg (the
component) to get the scrambled egg (the end product), but you cannot
reverse te process to get the egg again.

The same applies to your problem of the length of pipe and the washers.
After having cut up the length of pipe you have the washers, but you cannot
reverse the process (due to e.g. the scrap produced while cutting the
washers).

In order to solve your problem you have to look at what gross material you
need to produce the 1000 washers. It might be so that there is a need for
10% extra for the scrap factor.  Based on that information you device the
bom per standand unit of quantity.

With kind regards,

Pierre Smits

Thanks for the offer Pierre,

I keep your proposition in mind, for now I will keep the discussion open

Hi Rupert,

Have you tried setting up the BoM between Washer (Produced after passing through required operations) and Pipe (as a BoM component or raw material) in ratio of 1 : 0.001. Once you associate the Washer with proper routing and create production run then you should be able to produce 1000 units of washers and stock them in inventory by consuming 1 unit of Pipe (assuming that scrap factor is 0%).  I have not tested but MRP would also honor this BoM while generating the Procurement or Production requirement for Pipes based on demand for Washers from downstream operations or safety stock requirements  or sales orders or forecast in the supply chain.

Thanks,
Swapnil
