System dynamics analysis of COVID-19 prevention and control strategies

Shuwei Jia, Yao Li & Tianhui Fang

 Environmental Science and Pollution Research, 2022

摘要/Abstract

The COVID-19 pandemic now affects the entire world and has many major effects on the global economy, environment, health, and society. Focusing on the harm COVID-19 poses for human health and society, this study used system dynamics to establish a prevention and control model that combines material supply, public opinion dissemination, public awareness, scientific and technological research, staggered work shifts, and the warning effect (of law/policy). Causal loop analysis was used to identify interactions between subsystems and explore the key factors affecting social benefit. Further, different scenarios were dynamically simulated to explore optimal combination modes. The main findings were as follows: (1) The low supervision mode will produce a lag effect and superimposed effect on material supply and impede social benefit. (2) The strong supervision mode has multiple performances; it can reduce online public opinion dissemination and the rate of concealment and false declaration and improve government credibility and social benefit. However, a fading effect will appear in the middle and late periods, and over time, the effect of strong supervision will gradually weaken (but occasionally rebound) and thus require adjustment. These findings can provide a theoretical basis for improving epidemic prevention and control measures.

基于系统动力学的“互联网+健康医疗”体系模型

摘要/Abstract

“互联网+健康医疗”模式已然成为我国健康医疗产业发展的一个新方向,为解决传统医疗行业中存在的诸多问题提供了新思路。在分析”互联网+健康医疗”对传统医疗的影响及其发展机制的基础上,利用存量流量图等工具构建”互联网+健康医疗”体系模型,运用Vensim软件对我国”互联网+健康医疗”发展情况进行仿真,并模拟相关政策的干预效果。结果表明:”互联网+健康医疗”在降低潜在医疗需求(PMD)、促进分级诊疗中具有重要作用,保障医疗保险能够较好地嵌入”互联网+健康医疗”就诊流程中对降低PMD最有意义,而降低整体门诊价格对于优化就医结构、促进分级诊疗最为有效。 

基于系统动力学的智慧医疗云服务平台功能需求建模方法

摘要/Abstract

智慧医疗云服务平台是集多角色、多功能于一体的综合服务平台。鉴于现有平台的功能使用率低、数据不共享、平台架构混乱等问题,本文在解析平台角色的基础上,确定了系统需求边界,引入系统动力学方法,模拟平台内部各要素之间的相互作用和因果关系,实现需求分析的动态化和实时化,保证了所提取功能的有效性,提高了数据的共享程度,并通过各角色关系分析,进而厘清平台架构。
