This study develops a multi-level programming model for the planning shale gas-water supply chains. A set of leader-follower-interactive objectives with emphases of water consumption, economic performance, and pollutant discharge are integrated into a sequential decision-making process. Satisfactory degree is introduced to tackle the computationally challenging problem based on an interactive fuzzy approach. Operational decisions regarding water resources allocation, transportation mode selection, and pollutant discharge control would be achieved. Results reveal that the environmentally- or economically-aggressive strategies would be generated when a single goal for optimizing economic benefits or pollutant discharge. The multi-objective decisions are limited by the selected weights. However, the multi-level model would provide more comprehensive schemes due to its sequential consideration of the economic/environmental concerns. Findings from the multi-level model can facilitate (a) balancing the conflicts among different decision makers, (b) timing and siting for shale gas production, and (c) managing water resources for pollutant discharge control.

这项研究为页岩气-水供应链的规划开发了一个多层次的编程模型。一套以用水，经济绩效和污染物排放为重点的领导者与跟随者互动目标被整合到一个顺序决策过程中。引入令人满意的程度来解决基于交互式模糊方法的计算难题。将实现有关水资源分配，运输方式选择和污染物排放控制的运营决策。结果表明，当优化经济效益或污染物排放的单一目标时，将产生对环境或经济具有侵略性的战略。多目标决策受所选权重的限制。然而，多级模型将顺序地考虑经济/环境问题，因此将提供更全面的方案。多层次模型的发现可以促进（a）平衡不同决策者之间的冲突，（b）页岩气生产的时机和选址，以及（c）管理水资源以控制污染物排放。
