PARAMETER OPTIMISATION AND ADJUSTMENT BY THE SIMPLEX METHOD (Nelder-Mead)

EcosimPro is an excellent simulation tool with great potential and versatility. Taking advantage of its potential, the EL language was used to implement the non-linear simplex method in order to optimise any type of objective function. Some examples will be given: the simulation of a discontinuous chemical reactor (batch) in which the coolant temperature is optimised to minimise the concentration of reagents or the operating time. But perhaps the most useful example for EcosimPro users is the simulation of a desorption column. Experimental data retrieved from a pilot plant was used in this simulation. In this case, the simplex method was used to adjust the parameters of the model. The latter case is very useful because any simulation carried out with EcosimPro can be used to adjust the parameters and therefore the dynamic model can be validated.
