Build up a process to get capacity data

ehcor

Hello Community,

I don't know RapidMiner very well and have some questions and challenges. It would be great if someone could help me with that topic:

Please find attached the CSV file with example values. The file I'm working with is about 1.000.000 examples and 22 attributes.
I generate an attribute which counts the days between start and finish. There are various things I would like to solve:
- How can I find out how much is produced in which period on which manufacturing line?
- Can I display the capacity utilization of the production line? 
- For example, production line 1 can only produce 500 units per day. How can I determine when a production line is overloaded?

HI @ehcor,

Interesting project ! 
I propose the following process :

To execute this process, you have to set in the Set Macros operator parameters:
 - your "start date" (with strict respect of the format of the date of your existing date attributes "Scheduled_start" and "Scheduled_finish"
ie 'Apr 18,2018')
 - your "end date" (same rule as the "start date")
 - the "department" name you want to calculate the capacity (ie Prod1, Prod2 etc.)
Warning : your "end date" must be strictly later than your "start date".........(I know it's logical, but I precise it because RM can raise an error or deliver some false results in this case)



I have to make a few clarifications :
There are particular cases where your "start date" or your "end date" can be set between the 
"Scheduled_start" and the "Scheduled_finish" dates of one of a production period.
In this case, I made a simplifying hypothesis : I count the total production between the "Scheduled_start" and the "Scheduled_finish" dates
which overestimates the final total calculated capacity of a production department...(in deed, in this case, only a part of the scheduled production is in reality produced...) 
Rigorously, in these particular cases, I think that you have to linearly interpolate the production ==> This may be an improvment of the process...

In the end, after setting and executing the process, you obtain results like that :


You can test this process with your whole dataset and tell me what do you think.

Hope it helps,
