Considering just-in-time production, the mathematical model of flexible job-shop schedulingfor bi-objective is established. To solve the model, a genetic algorithm is developed. In this algorithm, a two-row chromosome structure is presented because of the special point of the model. At the same time, AOV network is applied to decode and compute the fitness function. Then selection, crossover and mutation operator of the genetic algorithm are designed. Finally, an example of job shop scheduling is shown.

An equal cross-section blade was investigated and a finite element model was built parametrically. Geometrical parameters (such as length, width and thickness), material parameters (such as young's modulus and density) and speed of blade were considered as input random variables while the static frequencies and dynamic frequencies were output random variables. Combining the finite element method, response surface method and Monte Carlo method, the statistical properties and cumulative distribution functions of static frequencies and dynamic frequencies were obtained. Probability sensitivities analysis, which combined the slope of the gradient and the width of the scatter range of the random input variables, was applied to quantitatively evaluate the sensitivities of static frequencies and dynamic frequencies with respect to the random variables. The Scatter plots of structural responses with respect to the random input variables were illustrated how to adjust the values of the static frequencies and dynamic frequencies by changing input random variables.

RCBV values calculated using cSVD and oSVD were identical. Both values were equal to the whole areas under the concentration-time curve were divided by the arterial input function areas.

The scatter plots of rMTT and Td were useful in stroke staging.
