its surprising to me how little work is done to make the tools which do this accessible considering how much money and open data there is.
it gets less open and more complicated is when you consider certain mills only can make certain cuts, produce certain products, and accept certain logs. then factor in distance between mills and the products they can make, and also log lengths accepted by the trucks which can travel those routes.
its all solvable and should be, but its so niche and that i still think there isnt an accessible solution
