When studying the evolution of complex systems one refers to model representations comprising various descriptive parameters. There is hardly research where system evolution is described on the base of information flows in the system. The paper focuses on the link between the dynamics of information and system evolution. Information, exchanged between different system's parts, before being processed is first provided with meaning by the system. Meanings are generated from the perspective of hindsight, i.e. against the arrow of time. The same information can be differently interpreted by different system's parts (i,e,provided with different meanings) so that the number of options for possible system development is proliferated. Some options eventually turn into observable system states. So that system evolutionary dynamics can be considered as due to information processing within the system. This process is considered here in a model representation. The model under study is Triple Helix (TH) model, which was earlier used to describe interactions between university, industry and government to foster innovations. In TH model the system is comprised of three interacting parts where each part process information ina different way. The model is not limited to the sphere of innovation and can be used in a broader perspective. Here TH is conceptualized in the framework of three compertment model used to describe infectious disease. The paper demonstrates how the dynamics of information and meaning can be incorporated in the description of Covid-19 infectious propagation. The results show correspondence of model predictions with observable infection dynamics.

翻译：研究复杂系统的演进时,人们会提到由各种描述参数组成的模型表达方式。 几乎没有研究在系统信息流动的基础上描述系统演进。 本文侧重于信息动态与系统演进之间的联系。 信息在系统处理之前在系统各部分之间交换, 系统首先提供意义; 含义来自后视角度, 即对时间箭头。 同一信息可以由不同系统部分的不同解释( 即, 提供不同含义的), 以便可能系统开发的选项数量激增。 有些选项最终会变成可观测的系统动态。 因此, 系统演进动态可以被视为系统内的信息处理过程。 在此, 以模型的形式来考虑这一过程。 正在研究的模型是Triple Helix(TH) 模型, 早先用来描述大学、 工业和政府之间的互动, 以促进创新。 在TH模型中, 系统由三个互动部分组成, 其中每个部分都以不同方式处理信息。 模型并不局限于创新领域, 并且可以在一个更宽泛的系统动态系统中使用。 系统进进进化的动态描述C 概念, 将C 展示进化的进化概念, 展示进化文件的进化框架。 。 C 展示进进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进化的进。 C。
