There’s this discussion on production planning but we find that in many cases the company does not intend or maybe even can do real planning.
The only thing the company wants is to know is what is the load of the different work centers and the overall production line.
What I mean by the term load is that the company wants to know what is the total number of hours a given work center (or work center category, etc) will be used by adding the planned time of all in progress and planned productions.
Sometimes the production manager to simply wants to be able to sort productions so they can have the sorted cumulative expected load.
Also, they want to know the total number of employee hours required to handle that load.
Is there a plan to implement something along those lines in Tryton?
What we did with the production_route module is to add a time, a quantity and a calculation field to the route steps, and that is quite simple and matches most needs.
Our production_route and production_operation modules have another design in which employees hours are considered work centers too. That is good for some cases, but not flexible enough when an employee can be working on several machines at the same time.
We would like to use core modules at some point but it’s not clear to me what is the path forward.
Thanks for opening up this question. We also faced similar questions.
I first tried to open up the discussion about those topics because I felt that it’s the path forward.
Along with other tools (Frepple) we developed some tools to help to plan
Centro de trabajo: Work center
Horas: Hours assigned to that work center
Dias y horas restantes: Hours converted to days (8h work time frame)
Fecha liberacion: Date on which this work center will be free to accept more work. So they know if they have resources to match a customer requested delivery date.
Concetración por maquina: Workload by work center.
3 section filters: Work center categories, work centers and employees.
At the main page the production with the estimated time, worked time, and remaining time.
At the right all the info about the production with some actions (frepple related)
Also there’s another custom view for employees where employee log in and sees the planned things assigned to the employee with all the detailed info along with some actions (start / stop).
Our asked requirements are quite similar to yours:
Estimated time on production works, so it can be planned on different work centers
Know the load of each category and work center (first image)
Assign employee to each work based on skills (frepple)
Extra:
Forward planning, not late (as Tryton and Community Frepple does) because some work centers are costless if they are filled with work (especially cut operations), and stopping the operation only because the production is planned for tomorrow is expensive. You want all the materials cuts ASAP as possible when all the factory is about metal, not JIT.
In our case we also faced the employee problem, because some work centers are semi-automatic (just require some supervision in some steps and employees can manage 4 semiautomatic work centers at a time) and others are totally manually.
But yeah, I would love to support some path forward in a direction that involves time and quantity (load) for production orders.
