Participatory approaches to develop community-based system dynamics models to tackle complexity are promising, but research is needed in how simulation models can be developed with community stakeholders to yield significant system insights. This study presents the results of a community-based system dynamics modelling process to increase water consumption and decrease sugar sweetened beverage consumption in Portland, Victoria, a regional town in Australia.
A series of group model building workshops with 11 community stakeholders addressing the topic of water and sugar sweetened beverage consumption was conducted in Portland. A simulating system dynamics model was built with stakeholders to inform action planning.
A system dynamics model was created to provide insight into water and sugar sweetened beverage consumption in Portland. The model included six feedback loops describing the causal effects of sugar sweetened beverage consumption habits and norms, water taste, water consumption norms, public water availability, and public health benefits. For example, the sugar sweetened beverage consumption norm loop modelled how people overestimating others' consumption may motivate an increase in their own consumption, feeding back and further amplifying an increase in sugar sweetened beverage consumption. The model contributed to the foundation of a strong partnership to improve the taste of water and educate the public on water consumption.
Engaging stakeholders in system dynamics modelling about water and sugar sweetened beverage consumption increased engagement and collaboration to address the problem among community stakeholders.
采用参与式方法开发基于社区的系统动力学模型以应对复杂性具有广阔的前景，但仍需要研究如何与社区利益相关者共同开发仿真模型，以产生有意义的系统见解。本研究展示了在澳大利亚维多利亚州波特兰市开展的一项基于社区的系统动力学建模过程的结果，旨在增加水的摄入量并减少含糖饮料的摄入量。
在波特兰市，与 11 位社区利益相关者进行了一系列小组建模研讨会，探讨水和含糖饮料消费的主题。与利益相关者共同构建了一个模拟系统动力学模型，为行动计划提供信息。
创建了一个系统动力学模型，以深入了解波特兰的水和含糖饮料消费情况。该模型包括六个反馈回路，描述了含糖饮料消费习惯和规范、水的口感、水的消费规范、公共水的供应以及公共卫生效益的因果关系。例如，含糖饮料消费规范循环模型描述了人们高估他人消费可能如何激发自己消费的增加，从而反馈并进一步放大含糖饮料消费的增加。该模型为改善水质和教育公众关于水消费的强大合作关系奠定了基础。
让利益相关者参与关于水和含糖饮料消费的系统动力学建模增加了社区利益相关者解决该问题的参与度和合作度。
