Absolutely not imo, thats one big waste of time for a new player... reserched items still have to be bought once they are complete and they arnt cheap, also it's a lucky dip as to whether you get anything worth having,
set your bunker to turn the supplies into weapon stock and sell every ~2hrs 20mins for $210,000
Without the workshop and staff upgrades is $150K for 25% Plus you will need more crates to keep it supplied as efficacy is not as good. The work to keep it supplied is so inefficient as a Solo player as you can make money much faster elsewhere, import Export for example.
