一个地下水管理模型，使用非线性规划算法，找到最低成本的设计相结合的泵和处理补救系统的泵和处理组件，包括系统的建设和安装以及操作和维护的固定成本。目标函数的固定成本条款被纳入非线性规划制定使用惩罚系数法。将该模型应用于具有均匀导水率的含水层的结果表明，包括固定成本的组合井场和处理工艺模型对这些系统的设计和成本具有显著影响，通过使用更少、更大流量的威尔斯来降低成本。先前的泵送和处理设计公式已经导致系统具有许多低流速威尔斯井，这是由于使用了不表现出规模经济或固定成本的简化成本函数。文中还列举了两个具有非均匀电导率场的含水层。
A ground-water management model using a nonlinear programming algorithm was developed to find the minimum cost design of the combined pumping and treatment components of a pump-and-treat remediation system and includes the fixed costs of system construction and installation as well as operation and maintenance. The fixed-cost terms of the objective function are incorporated into the nonlinear programming formulation using a penalty coefficient method. Results of applying the model to an aquifer with homogeneous hydraulic conductivity show that a combined well field and treatment process model that includes fixed costs has a significant impact on the design and cost of these systems, reducing the cost by using fewer, larger-flow-rate wells. Previous pump-and-treat design formulations have resulted in systems with numerous, low-flow-rate wells due to the use of simplified cost functions that do not exhibit economies of scale or fixed costs. Two example aquifers with heterogeneous conductivity fields were al...
