Combine Recipe

Hello, I have 10 raw materials and 15 items. Items are created by combining different portions of the raw materials. I have built a model that simulate this process but I was wondering if there is any other approach that is more efficient. Currently I have 10 different ports for my raw materials and in my real-world problem there are many more raw types. Is there a way to avoid having separate ports for each raw? Also, for the combiner is there a way to specify different processing times for different raw materials?

Hey @MohammadMajd, I think I have a solution that may work for you. It's a simple layout but powerful solution.

I started by making a Process Flow that is in charge of making the raw material in a queue.

The change visual is just to color the boxes so you can differentiate different material as they're used in recipes. I used the same table you used in your model to spawn them. Same goes for spawning items; however, I took a different approach for those.

I viewed items coming in as "Requests for materials". So what I did was push all raw material to a list so I could pull them from that list. Essentially, I took each incoming recipe and got their required ingredients from the Recipe table (that you provided). I made a Map of their raw material and how much. Then I pulled that amount of each from the list. I moved them into the "IngredientQueue" for a second before moving them into the Combiner. Then I have them wait there, combining them with a pallet. I move the finished product to a queue.

From here, instead of combining the ingredients with a pallet, you could transform that pallet and the ingredients into a different shape and color to signify their combination. Hope this helps.

You could also look at the opportunistic combiner example model, which doesn't allocate any until it has all those needed for an assembly.

@Kavika F I went through your model and understood the overall function of the ProcessFlow. But I have some questions about the details of it. Is it possible to set up a call so I can ask my questions?

@MohammadMajd What questions do you have? Other users may have those same questions. If you post them here I can respond to them.

1. How can I learn more about lists? Specifically how the list is connected to the Recipe table?

2. How can I modify this model to use operators to transport and process raw materials?

3. How can I have specific delay times for each raw material/item?
