DESCRIPTION:Prof. C. de Prada Moraga\, Dpt. of Systems Engineering and Aut
 omatic Control (University of Valladolid). \nProcesses involving continuou
 s and discrete elements or variable structure are known as \nhybrid system
 s\, and the associated optimization problems are denoting as mixed integer
  \ndynamic optimization (MIDO). The talk provides an overview of some meth
 ods and tools \navailable for dealing with MIDO problems using the so-call
 ed sequential approach\, where \nthe optimization algorithms are combined 
 with a dynamic simulator in order to compute cost \nfunctions and constrai
 nts. A parameterization is proposed that allows converting the MIDO \nprob
 lem into a NLP one\, saving computational time. The talk also examines the
  problems \nassociated with the evaluation of the gradients when discontin
 uities take place in the inputs \nor the model due to its hybrid character
 . Some real life examples are provided to illustrate \nthe method: A cryst
 allization section of a sugar factory\, the optimal start-up of an \nevapo
 ration station and the optimal operation of a desalination plant.
