Optimizing Item Allocation and Supply in Manufacturing with Timing Constraints

Hi, 

I am currently working on a storage location assignment problem, which involves optimizing the allocation of various items with different dimensions to different storage areas. My model comprises two phases: warehousing, where there is one storage area with a specific number of racks, and manufacturing, which has its storage area and a specific number of racks as well.

In this problem, I aim to determine both the number of supplies for each SKU item and the allocation of storage spaces for each item. These allocations need to adhere to the capacity constraints of each storage area while maximizing the production of final products. Each final product or order is a combination of several items.

While addressing this problem, I've noticed that there are processes in manufacturing and for final products that have timing considerations. This makes the problem somewhat resemble a flexible flow shop scheduling problem. However, unlike traditional flow shop scheduling, I am not looking to minimize makespan. Instead, I want to focus on the allocation of items to space and the supply of each SKU item based on the entire process of warehousing and manufacturing.

Could you please help me identify the specific type of problem or hybrid problem that my model falls under? Also, how can I get help on formulating this problem?
