Parallel processes in Manufacturing.

[brijesh m]

Hi friends,
I am trying to configure the below routing having routing tasks A,B,C,D,E and then finished product got produced.

     A------>B----->D----->F---->Finished Product
     |                               ^
     |------>C----->E--------|

Actually my main aim is to explore how OFBiz handles the parallel processes which are very much the case in manufacturing units. I have tried some tricks but didn't able to get it. The thing is that in routing you can't add two routing task with same sequence number which restrains the below routing scenario. Please have a look at it and suggest the solution I am sure many among us have encountered this issue at some point of time.


Thanks
Brijesh M

someone else my correct me, but ofbiz has a basic system.
you can look at the data model book for manufacturing.
there may be some coding that needs to be done.
I am hoping that the project module can be tied into manufacturing so
the you can have Gnatt and Pert charts to evaluate processes and when
they can be done
this would then allow for parallel processes.

Hey BJ: I know you're trying to help, and you often do, but if you don't know why guess? You risk either spreading FUD about OFBiz or leading someone in the wrong direction.

On this topic, personally I would even prefer to defer to Jacopo to comment.

Sorry, what was that? You "thought you had it down"? Now I'm confused.

I commented on this because you started your email by saying that you didn't have it down: "someone else my correct me, but ofbiz has a basic system. you can look at the data model book for manufacturing. there may be some coding that needs to be done."

My interpretation of what you wrote, in the same order, is roughly: "I'm not sure what I'm talking about, but I think the stuff in OFBiz is pretty basic. Look in the Data Model Resource Book for more information on manufacturing because I don't really know. Even though I don't know if OFBiz supports this or not, I do know that if it doesn't then some coding may be needed."

That may be a big misinterpretation, but if it's not too far off the mark then what you do you mean by "thought I had it down"?

actually I used that because I was also proposing something, and it was
a polite way of leaving the door open.
but your criticism is accepted.

My suggestion, and this is what some of our (HotWax Media) customer  
actually do, is to reorganize your bill of materials and routings in  
the following way.

Let's say that the finished product id is "XYZ"

You could define the bill of materials of XYZ in the following way:

XYZ
|
|_______> semi finished product (or wip aka work in process product)  
XYZ1
|_______> semi finished product (or wip aka work in process product)  
XYZ2

And its routing would be just F

The routing for XYZ1 would be: A+B+D
The routing for XYZ2 would be: A+C+E

You create three production runs:

* one for XYZ1
* one for XYZ2
* one for XYZ that depends on the above two (i.e. it is executed after  
the above two are completed)

Hope it helps,

Jacopo

PS: if you define the products XYZ1 and 2 as WIP (productTypeId) and  
you create the production run for XYZ the system will automatically  
create the three production runs and their dependencies.

Hi jacob

Today i was trying to run one production run which had just 2 tasks.


A--------------------->B-----------------> Finished good
            c

Task A is producing work-in-progress item c


Task A is using raw material a,b
Task B is using raw material c,d( c is the output of task A)

i created BOM like this

finished good composed of

Raw material a,b .....Task A
Raw material c,d.......Task B


So while running my production run ......it was not showing requirement of
item C. Why?....
i m guessing that i need to create BOM for c also? is it?

I think if i wont create BOM for c (which is composed of a,b and Task A),
how will the system know
how much a,b will product how much of *c*

and after completing task A ,inventory is showing work-in-progress material
c , but it dint get subtracted
after task B gets finished(since it is using WIP c). why ?

hi jacopo

Sorry Jacopo , earlier i had written wrong name of urs. So sending my query
again .


Today i was trying to run one production run which had just 2 tasks.


A--------------------->B-----------------> Finished good
            c

Task A is producing work-in-progress item c


Task A is using raw material a,b
Task B is using raw material c,d( c is the output of task A)

i created BOM like this

finished good composed of

Raw material a,b .....Task A
Raw material c,d.......Task B


So while running my production run ......it was not showing requirement of
item C. Why?....
i m guessing that i need to create BOM for c also? is it?

I think if i wont create BOM for c (which is composed of a,b and Task A),
how will the system know
how much a,b will product how much of *c*

and after completing task A ,inventory is showing work-in-progress material
c , but it dint get subtracted
after task B gets finished(since it is using WIP c). why ?
