Abstract：
Wastewater treatment facility location selection and network design issues have become attractive topics in the field of wastewater management due to increasing human population, resource scarcity, environmental concerns, and rise of necessity for sustainable solutions for future policy designs. Especially in areas where the demand for wastewater treatment increases dramatically over the years because of reasons such as high migration levels, rapid industrialization, and tourism activities, the problem turns out to be more critical and dynamic. The existing studies try to deal with the issue through mathematical modeling approaches based on optimization perspectives, which require significant computational effort. In this study, an alternative approach based on system dynamics (SD) method is proposed to examine the complex dynamic and nonlinear structure of wastewater treatment facility location selection and network design problems. The proposed SD simulation model is designed for a densely populated industrial and tourism spot, the city of Antalya, located on the Mediterranean coast of Turkey. The model is capable of determining where and when to build a new wastewater treatment facility as well as generating the generic wastewater network structure to be built for the five districts situated in the city center based on cost issues for 2015-2040 period. In addition, the impacts of demand level changes for wastewater treatment due to population variations are analyzed via several scenarios to help decision makers to develop sustainable and cost-efficient management policies. Although SD is a frequently utilized approach in the water/wastewater management arena, to the best of our knowledge, this study is the first attempt to examine the complex and dynamic nature of wastewater treatment facility location selection and network design problems through SD approach.
摘要：
由于人口的增加，废水处理设施的位置选择和网络设计问题已成为废水管理领域的诱人话题，资源稀缺，环境问题,以及未来政策设计的可持续解决方案的必要性上升。特别是在由于高迁移水平等原因，污水处理需求多年来急剧增加的地区，快速工业化,和旅游活动，问题变得更加关键和动态。现有的研究试图通过基于优化视角的数学建模方法来解决这一问题，这需要大量的计算工作。在这项研究中,提出了一种基于系统动力学（SD）方法的替代方法，以研究污水处理设施位置选择和网络设计问题的复杂动态和非线性结构。所提出的SD模拟模型是为人口稠密的工业和旅游胜地设计的，安塔利亚市,位于土耳其地中海沿岸。该模型能够确定何时何地建造新的废水处理设施，并根据2015-2040年期间的成本问题为位于市中心的五个地区建造通用废水网络结构。此外,通过几种情景分析了人口变化对废水处理需求水平变化的影响，以帮助决策者制定可持续和具有成本效益的管理政策。尽管SD是水/废水管理领域中经常使用的方法，据我们所知,这项研究是首次尝试通过SD方法检查污水处理设施位置选择和网络设计问题的复杂性和动态性。
