利用线性系统理论中响应函数的概念，建立了承压均质非均匀含水层的随机地下水管理模型。库珀-雅各布方程用于开发单位响应函数。该模型明确地考虑了渗透率和存储系数的随机性，这使得在一个指定的系统性能可靠性要求的井场最佳抽水模式的确定。一个假设的例子被用来证明模型的适用性。模型结果的可靠性要求和含水层参数的不确定性水平的影响进行了检查。进行后优化模拟以检查模型的性能并进一步评估其有用性。
A stochastic groundwater management model for a confined, homogenous, and nonuniform aquifer is developed using the concept of response function in the linear system theory. The Cooper‐Jacob equation is used to develop the unit response function. The model explicitly considers the random nature of transmissivity and storage coefficient, which enables the determination of optimal pumping pattern in a well field subject to a specified system performance reliability requirement. A hypothetical example is utilized to demonstrate applicability of the model. Model results affected by reliability requirement and uncertainty level of aquifer parameters were examined. A post‐optimality simulation is conducted to examine the performance of the model and to further assess its usefulness.
