Red chip supply problems in your factory are usually caused by insufficient plastic bars, which is usually caused by oil production backing up because you're not consuming your heavy oil and/or petroleum fast enough.

Crack heavy oil to light, and turn excess petroleum into solid fuel. As a further refinement, you can put these latter conversions behind pumps, and use the circuit network to only turn the pumps on when the tank storage of the respective reagent is higher than ~80%.
