Supply-demand pinch based methodology for multi-period planning under uncertainty in components qualities with application to gasoline blend planning

Uncertainty in component quality in gasoline blending due to measurement errors and variation in operation leads to planned blends which may not meet quality specifications and re-blending is required. Formulating gasoline blending as chance constrained programming enables a decision maker to decide what percentage of blends will be guaranteed to meet the specifications and balance the increased cost of blends vs. the cost of having to re-blend …
