<p class="MsoNormal">I am no ERP expert. I am trying to develop useful analytics on top of data generated in the supply chain.<o:p></o:p></p>
<ul type="disc">
<li class="MsoListParagraph" style="mso-list:l1 level1 lfo5">“what happens to part numbers”: no research that has been published, as far as I know. Just empirical experience. Because of significance added to part numbers, program identifiers for example. In
many companies, engineering departments feel the need to “re-number” a part when re-using it, because it is used on another program. End result: many different part numbers are referencing exactly the same part. All this significance also discourages efforts
to try to re-use topology: it is easier to slightly change a part (to make sure it legitimately gets another part number) than to try to deal with the issue of significance in part numbering. This is an industry wide problem.<br>
It is my opinion that we risk the same, if we introduce significance to the serial number.
<br>
I agree, we have to have a human readable. No doubt. It has to be there. But let’s back it up with a UUID so that we can do data analytics easier.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l1 level1 lfo5">Are we proposing to store serial numbers in STEP? This feels to me like an ERP issue to me. Which I am not an expert in.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l1 level1 lfo5">Agree, the serial number is unique in the context of the part number. Still, I think it would make sense to have a UUID go with that human readable form of the part/serial number. Makes it much easier
on the analytics.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l1 level1 lfo5">I get your point of the tuple. But if you push that to its logical end, you can add even more information in that collection: let’s add the Engineering Requirement as well. The tuple includes 4 data
items: pn, sn, er, UUID:<o:p></o:p>
<ul type="circle">
<li class="MsoListParagraph" style="mso-list:l1 level2 lfo5">pn = 33, sn = 1, er = 1, UUID = x3d<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l1 level2 lfo5">pn = 33, sn = 2, er =1, UUID = x6e9<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l1 level2 lfo5">
pn = 55, sn = 1, er = 1, UUID = xcfdd<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l1 level2 lfo5">
pn = 55, sn = 1, er = 2, UUID = x45ba<o:p></o:p></li></ul>
</li></ul>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in">
I think that the problem will be (but bear in mind that I am no expert in this either) to uncouple these. If we do the above, how can I easily find all “pn = 33”’s that have been made against er=1. Or which serial numbers? I think that it is far easier to create
data source searches if each pn has its own UUID, each sn has its own UUID and each er has its own UUID. Again, Jan’s opinion.<br>
<br>
In the past, I have shown the following picture (courtesy of Mitutoyo): it shows a UUID for each item (pn, sn, each er). When going to a different sn, only the UUID for that sn changes. The other ones stay the same. That makes a lot of sense to me. Seems easy
to search for data that way. <br>
<br>
<img width="884" height="389" style="width:9.2083in;height:4.052in" id="Picture_x0020_1" src="cid:image001.png@01D89A97.D3A33F60"><o:p></o:p></p>
<ul type="disc">
<li class="MsoListParagraph" style="mso-list:l1 level1 lfo5">Indeed, we can’t fix human fallacies through standards, but we can create systems that make it less easy to generate these fallacies. To me, that starts with things like the v5/v4 discussion. By adding
v5 in there, you open the door for significance, which we, humans, will grab a hold off and push to the limit. We are wired like that. If we go v4, that will never be an option. To me, that would be an example where we can have an effect on the amount of fallacies
humans can introduce to the system. <br>
Therefore, when it comes to UUID’s, my preference on UUID’s remains v4, as I am extremely worried that if we allow v5’s, then human tendency will be to add significance to the UUID, which brings us back to the significance trap in the first place.

<p class="MsoNormal">We are still in a world where we do a lot of the manufacturing orchestration by hand. That drives the need for human readable forms of these identifiers. But long term, as orchestration processes get automated, there is a need for UUID’s.
Since humans are going to be always in (or at the very least close to) the loop, human readable forms are important. But the inconsistencies that that brings, need to be countered by a UUID, which will take a more and more central role as automation get s
introduced.<o:p></o:p></p>
