A couple of suggestions, leave a Chinese base in Chinese hands to train your bombers. Just make sure that the Allies can't base fighters in the area for CAP purposes. Leave a base with a level one airfield within kamikaze activation range so they can come into play as soon as is possible. You might also bomb the port at that base in case any crippled subs try to make repairs there.

So, now that I've got it, what do I do with it? As a result of the capture all the "stuff" there has been reduced to 1 - that's 1 resource, 1 light industry, 1 heavy industry, 1 refinery, 1 oil, and 1 repair shipyard. As much as Japan needs oil, I am NOT going to spend 189,000 supply to fully repair the oil facilities. What I'm thinking is spending 45,000 supply to fix all but resource to 10. But, most of that won't happen until Java is completely captured, as supply is needed for combat operations and fortification. The order of repair will be oil, heavy industry, refinery, light industry, shipyard.

Soerabaja, same happened in my latest AI game.
As I can spare the supply I am repairing all Oil, I expanded the RSY to about 20 to allow repair of CAs and a few other things at the same time.
I repaired Refineries to about 40-50 to make some local fuel for the navy to use each day
Im not repairing HI, LI or Resources at all. I thought about HI but it will take me so long to repair all the Oil I decided against it.
Each Oil turns into something like 9 fuel and the Home Islands have an excess of Refineries so I feel that repairing Oil centres is worth it to try and keep them producing fuel for longer.
It’s “only” 189k Supply

Each industry takes 1000 supply to repair. Light industry produces 1 supply per day, which means that every factory you repair will take 1000 days (2.74 years) to turn into profit.

Heavy industry is better with 2 supply produced per day, so 1.36 years to pay off plus some Heavy industry points.

That is if you have enough Resources to feed them, and if you need to ship in/repair Resources as well, your pay off is even farther away.

Right, I realize all that - but 9k supply to get some local LI going is a small price to pay. If resource needs to be shipped in (not likely), there's plenty at Bandjermasin across the Java Sea. So far, 1 oil point has been repaired; none of the others have started.

This is the argument I faced many years ago with rebuilding damaged supply in Bangkok Certainly the war would end before it would be worth the investment. But producing supplies on a rail line meant propagation of supplies that was worth a savings in fuel to ship supplies to Bangkok. At least my calculations. Besides I had the supplies to spare ;).

Look at it another way, if you save the supplies by not repairing you will not collect interest . . .

It does not work that way because word "interest" usually assumes you will also get your initial deposit back on maturity. In our case it a return on sunk investment. NPV can be calculated just fine anyway
