Products and process strategies selection has attracted much attention, especially for produced water management. In order to select best alternatives, it is necessary to develop a comprehensive decision-making methodology applicable to complex and uncertain systems. In this paper, we propose a new network-based methodology of decision-making. Firstly, the discrete quantitative and qualitative input data are mapped into networks based on ordered visibility graph. Then we take advantages of network topologies, which are node degree and node distance, to establish the relationships among the input data. Finally, the data are aggregated into a single value to make a decision. The case study indicates that our method is advantageous to make decisions objectively while inheriting the characteristics of network structures.

产品和工艺策略的选择引起了广泛的关注，特别是在采水管理方面。为了选择最佳替代方案，有必要开发一种适用于复杂和不确定系统的综合决策方法。在本文中，我们提出了一种新的基于网络的决策方法。首先，基于有序可见性图，将离散的定量和定性输入数据映射到网络中。然后，我们利用节点度和节点距离等网络拓扑来建立输入数据之间的关系。最后，将数据汇总为单个值以做出决定。案例研究表明，我们的方法在继承网络结构特征的同时，有利于客观地做出决策。
