ŒfÚŽGŽi‰pjF PROCEEDINGS OF THE SYMPOSIUM ON SYSTEM OPTIMIZATION
’˜ŽÒi‰pjF Ikumasa YOSHIDA, Tadanobu SATOU, Yukio ADACHI
ƒ^ƒCƒgƒ‹i‰pjF BASIC STUDY ON OPTIMAL SEISMIC SENSOR LOCATIONS
´˜^i‰pjF Optmal location for placing seismograph along freeway is discussed. First the theory of spatial distribution estimation of earthquake intensity is presented and the index which indicates the quality of the sensor locations is proposed based on the estimation error of the spatial distribution. The optimal sensor location problems can be formulated as optimization problem in which the objective function is the sensor location index and design parameters are locations of the sensors. Real coded GA is used for the optimization. After the outline of the real coded GA is presented, optimal sensor location is determined by using the proposed methodology.
