Permutations With Repetition and other constraints

I have a project I’ve been working on for work. I’ve been searching the internet for a similar solution for a few weeks and haven’t been able to find a close enough solution that I can modify.

I’m trying to maximize the useable product off of a manufacturing machine that is 280” (inches) wide. We sell the product in different widths. So I am ultimately trying to create a tool that will allow me to input the different widths that I need and then find the permutations that fall between 275 & 280". From there, I’ll find the best permutations from the generated list that I can use to manufacture all of the needed product.

When I’ve looked at different examples, it appears that I’m looking for permutations with repetition.

The other requirements that I need are:
• With repetition – so that one size could be used multiple times in the solution
• Need the Permutations to be between 4 and 9 widths at a time. Meaning I could use 70” 4 times to get 280”, 31” 9 times to get 279” or any other combination of widths to get between 275 & 280”
• I need to be able to input between 15-25 widths for the macro to be able to process
• Any permutation that doesn’t fall between 275 & 280” should be discarded or not included in the final list
• Generate a list of valid permutations in a 9 column table with the sum of the widths in the 10th column

The closest example I could find to this was located at Generate all possible permutations given input values

I don’t know how to modify it to meet my needs.

Any help would be greatly appreciated.
