摘要
在控制害虫不超过经济临界水平的前提下,考虑实施一次不同控制方案时花费最小的控制策略,即寻找脉冲喷洒农药和投放天敌等的最佳组合使得总的花费达到最小问题.利用LambertW函数的定义和性质以及Lagrange乘子条件得到了一次脉冲作用下的成本.结果显示综合控制的成本是最优的.
Different one time control tactics are investigated when the numbers of pest are not larger than the economic threshold, and the optimal combination of spraying pesticides and releasing in natural enemies in terms of cost are addressed. The sufficient conditions which guarantee the existences of the optimal strategies in terms of cost are obtained by using the definition and properties of Lambert W function and Lagrange multiplier. The resuits indicate that the integrated control strategy is the optimal.
