In my free time for the past few days I've been rewriting the NewHarmony planning program from Julia to R (this has been taking me quite some time since i've also been using it as a way to teach myself linear algebra).
I got to the part where it takes in the estimated labor pool for the future as well as the annual target final consumption for each product and I felt that a core part of "planning" was missing: optimizing over the 5 year period.
If the targets for all goods are set each year manually, then there is some part of the plan that is still done manually. Is there a way to set a goal 5 years into the future and produce, using the information from the IO table and capital depreciation table and capital stock table, the targets for intermediate years?
You can achieve this by having the amount of goods at year N by equal to the goods at year N-1 + new goods produced - goods used up or depreciated and then setting a constraint that good X should be >= some amount at N=5. Hagberg and Zachariah's rhp project that was posted on here can do this I think. Certainly it carries output from one year into the next one.
