blend. It did so based on the properties of available stocks and blend proportions suggested by the blender. Then‚ by the 60’s computers advanced quit a bit. Linear programming models were being solved by linear programming introduced by the refiner engineers. A process optimization program for nonlinear optimization that solved nonlinear programming problems was developed by IBM‚ called POP II. Then‚ immediately after‚ the GOP blending optimization system was developed that used the POP II system.
