Study on optimization of parameters in a biological model

According to the data observed in a China-Japan Joint Investigation,the parameters of an ecosystem dynamics model (Qiao et al.,2000) were optimized.The values of eighteen parameters for the model were obtained,with nutrient haft saturation constant,K_n=1.4 μmol/dm³,K_p=0.129 μmol/dm³ and Ks=1.16μmol/dm³ for the diatom and Kn=0.345μmol/dm³,Kp=0.113 μmol/dm³ for the flagellate.Three proposals to set up a function for this multiple objective problem were discussed in detail.
