As groundwater resource in irrigation district is affected by many factors,evaluation of groundwater carrying capacity is a multi-objective optimal problem.A multi-objective quantitative evaluation model was established, which included four objectives,i.e.,GDP, grain yield, population and COD emissions. The improved Differential Evolution (DE) algorithm was built and adopted to solving the multi-objective...
Mine fire not only brings about great loss of coal resources and damage the whole mining system, but also causes the massive personnel casualty. Based on the air distribution request of the mine ventilation network, solves airflow quantitative optimizing control to the mine ventilation system network's nonlinear programming mathematical model using harmony annealing search, fuses the dynamic perturbation...
