save current simulation status to custom parameter

Hello,

I'm trying to create RL agent and I need to send a lot of information to it via custom parameter.

It's about a job shop scheduling optimization so I have multiple jobs (objects) each of them have multiple operations (processors).
I think I need a Map since the information that I need to send will look like that :
obs[TokenId?] = [current step id, next destination, time to finish the current step, time to finish the whole job ,... ]

I thought about tokenId but not sure if this is a unique identifier for each job/token.

I can have x simultaneous jobs/tokens so I need to send all these information to my RL ( maybe I'll have another question about custom observation space later on)

so the idea is that my RL agent should know all about current processing, left time for each processor , occupied processors , .... )
I need your help to figure out how to do that :) hoping that my question is clear enough!

Regards!

Hey @BaraaM, do you have a model you have that you could post that demonstrates the basic processes you're trying to model? It would help us a lot if you gave us some concrete information to work with such as a input material rates, how many different processes there are and what they entail, are there operators involved, if so how many, etc. Thanks!

Hey @Kavika F thank you very much for your answer, I saw the notification for your comment yesterday. For the moment I used "attrs.uniqueid.value" to get the id and I was able to get the information from my jobs using custom user commands. I'm still having some problems about communicating all of that with my RL model but I think I'll put another question about this problem.

Thanks!
