In this research, aiming at the highly efficient small artificial lung, the membrane area was made fixed in 0.3m^2, and housing form was optimized. Minimization of the standard deviation of the blood flow velocity in the hollow fiber membrane(sddv) as improvenent in gas exchange performance, minimization of blood pressure(pdrop) and minimization of a blood fill ration(pv) as biocompatibility, and minimization of the domain of 0.5 or less mm/s of the blood flow velocities(v5mm ) as reduction of thrombosis were set up in objective functions. In addition, calculating for the relation between objective functions and design variables by multiple linear regression analysis using many solutions produced inevitably, it is thought that will get new indexs of a future design. The excellent result was able to be obtained from the analyzed result on optimization of the artificial lung. Moreover, it was suggested from the relation between objective functions and design variables that the volume of a hollow fiber membrane is the most important.
