Thanh Thanh company has the main factory at Cu Chi province and two outsource factories at Dong Nai province. Every month, the planning team need to allocate the list of products with around more than 50 items (more than 60 containers) to their three factories, so, they have to work and optimize with the complex information as below:

1. The capacity of each factory: based on the volume of fine wood and separate for semi-product and finished-product.
2. The commitment capacity with each client.
3. The normal orders (around 35 orders) and stock orders (around 12 orders): some clients just make stock orders, so it’s not priority if the factory is full capacity.
4. Some special products need the specific factory.
5. The latest day shipping of each order.
6. The volume of fine wood for each product based on BOM.

Based on that, the manager needs the output results with very detail information as below:

1. The list of products of each factory that can satisfy their capacity per week.
2. The list of products on stock order need to put in production.
3. If one factory makes the semi-product and the other factory completes, need to define when the semi-product will be sent for the complete step to optimize their process.
