create a system pulled by forecast sales without using a process flow

[celia_li]

[ FlexSim 21.0.0 ]

Hello, I want to model on Flexsim a system pulled by forecast sales spread over a week (for example 50 product required for saturday, 100 for sunday etc) and I don't know how I can model this on Flexsim. I thank you in advance for your help.

Hi @Célia LI

I'm not entirely sure what you're asking.

You can use an arrival table to determine how many items enter the model at a given time by changing the arrival style on a source to Arrival Schedule

and then determine how many items per day (this model's time units are hours) in Edit Table

Is this what you are looking for?

I thank you for your response. I initially modeled it like this (using arrival schedule) but in that case I think that it would be a push strategy and not a pull one (because it starts from the source). I am rather looking for a way to start it from the final stock and then go up gradually to the source, if it is possible. I have to model a company based on a pull system.

Ah, I see. I believe this could be done with ProcessFlow, using a list for product inventory and a Pull from List activity acting as the product sales.

Ok thank you, I was looking for a way to avoid using a process flow but if it is the only solution I will do it like that !

Celia,

the concept of Lists is available in 3D modelling as well, not in Process Flow only:

You will want to check the user manual´s "Working With Lists" topic.
