Flexibility index synthesis

In the synthesis of resilient HENs, use of the class 1 flexibility index target offers two important features (Colberg et al., 1988) ... 

The Inherent Safety Index, ISI, was developed to consider a wider range of factors affecting the inherent safety of the process (Ch. 8). The ISI allows the evaluation of inherent safety of process alternatives to be done in a computerized process synthesis environment. The represented synthesis approach allows the inherent safety comparison of process alternatives to be done flexibly and interactively in the conceptual design phase.
