CSP-Based Mechanism Reduction

Computational singular perturbation or CSP analysis also provides informatimi oti the contribution of the rates of the reaction steps to the various timescale modes within a model. It can therefore be used to identify redundant species and reactions as part of a model reduction procedure. The CSP methodology has been introduced in Sect. 6.4, and here we discuss aspects related to mechanism reduction. We continue the use of notations that were introduced in Sect. 6.4. 

In the CSP methodology, several characteristic values (called indices) were derived (Kourdis and Goussis 2013), which allow the analysis and reduction of reaction mechanisms. 

The sum of the absolute values of is equal to unity. A relatively large If I value indicates that the -th reaction step is a significant participant in the w-th equilibrium. 

The contribution of the -th reaction step to the evolution on the SIM of the -th variable can be evaluated with the help of the CSP Importance Index
