komplexných reak£ných systémov 
Boris Fa£kovec 
’kolite©: prof. Ing. Igor Schreiber, CSc. 
25. november 2011 
Ústav chemického inºenýrství, Vysoká ²kola 
chemicko-technologická v Praze
Úvod a zadanie úlohy 
I Komplexné reak£né siete stretneme pri ²túdiu 
metabolizmu, mechanizmoch chemických reakcií, 
chemických reaktoroch atd. 1 
I Modelujeme sústavou oby£ajných diferenciálnych rovníc, 
ktorá je ur£ená stechiometriou siete 
_x = f(x) = Sv (1) 
kde S je stechiometrická matica a v vektor reak£ných 
rýchlostí. 
I Priestor reak£ných rýchlostí v stacionárnom stave je 
nulovým priestorom x. 
I Iba jeho £as´ v kladnom ortante ! rozklad na 
elementárne podsiete 
1Stability of complex reaction networks. Clarke B.L., Adv. Chem. 
Phys., 1980, 43, 1
Ur£enie stability siete 
I Pri ur£ovaní stability ²tudujeme maticu linearizácie 
J = S(diag(vs))T (diag(xs))1 (2) 
kde kappa je kinetická matica, ktorej prvky sú denované 
ij = 
@lnvj (xs) 
@lnxi 
(3) 
I Skúmame v²etky hlavné subdeterminanty B. 
B = S(diag(vs))T (4) 
Ak je jediný záporný, sie´ je nestabilná.
Dekompozícia na podsiete - implementácia 
I Algoritmus Schilinga, Letshera a Palssona 2 
I 2-kroky v kaºdej iterácii, iterácií ako po£et zloºiek 
 kombinácia 
 odstránenie redundantných riadkov 
I Iteratívna implementácia druhého kroku - zásadne zníºi 
výpo£tovú náro£nos´ 
2Theory for the Systemic Denition of Metabolic Pathways and their 
use in Interpreting Metabolic Function from a Pathway-Oriented 
Perspective, Schilling C.H., Letscher D., Palsson B.O., J. theor. Biol. 
2000, 203, 229-248
Ur£enie stability kombinácie 2 sietí - implementácia 
I Stena denovaná analyticky ako kladná lineárna 
kombinácia 2 hrán. 
I Skon²truuje sa matica - symbolický zápis 
I Subdeterminantami sú polynómy - numerická interpolácia 
I Ak má polynóm kladný kore¬ alebo je v ©ubovo©nej 
kladnej hodnote záporný, sie´ je nestabilná 
I Problém v robustnosti
