A numerical technique for Total Site sensitivity analysis

► Total Site Sensitivity Table (TSST) is introduced for exploring the effects of total site operating variations. ► A new numerical tool for heat integration was developed, the Total Site Problem Table Algorithm (TS-PTA). ► A simple new method for calculating multiple utility levels for both the PTA and TS-PTA is described. ► The Total Site Utility Distribution (TSUD) table can be used to design the total site utility network.
