Abstract Information source selection (ISS) is ubiquitous across a myriad of scientific disciplines. Previous studies mainly viewed the issue of ISS as a multi-criteria decision making (MCDM) problem, and therefore used MCDM methods to investigate it. However, many important aspects, for example, the dynamic process of ISS, the impact of different kinds of factors on ISS, and the stability of the solution of ISS, have not attracted enough attention and are still lacked of deep investigation. In this paper, an evolutionary game model is proposed to study this issue from theoretical perspective. That is to say, an ISS game is developed to formalize the interaction relationship between information sources, and replicator equation about population dynamics is used to mimick the dynamically evolutionary process in ISS. Within the proposed model, two kinds of factors, subjective factors and objective factors, have been separately considered and their respective influence on ISS has been distinguished. Furthermore, the dynamic process of ISS is presented clearly, and the stability of the solution is also investigated mathematically. Illustrative examples show that the proposed model sheds new light into the issue of ISS.

基于演化博弈论的信息源选择模型

摘要 信息源选择 (ISS) 在无数科学学科中无处不在。以往的研究主要将ISS问题视为多标准决策（MCDM）问题，因此使用MCDM方法对其进行研究。然而，国际空间站的动态过程、各种因素对国际空间站的影响、国际空间站解决方案的稳定性等许多重要方面还没有引起足够的重视，还缺乏深入研究。本文提出了一个演化博弈模型来从理论角度研究这个问题。也就是说，开发了一个ISS博弈来形式化信息源之间的交互关系，并利用种群动态的复制方程来模拟ISS中的动态演化过程。在提议的模型中，分别考虑了主观因素和客观因素两种因素，区分了它们各自对国际空间站的影响。此外，清晰地呈现了ISS的动态过程，并对解的稳定性进行了数学研究。说明性示例表明，所提出的模型为国际空间站问题提供了新的思路。
