Abstract

E-waste is a hazardous concept for human health, environment and businesses, and therefore, risk assessment is essential to eliminate or reduce the negative effects of e-waste in a circular economy. Decision-making plays an important role during the risk assessment in e-waste recycling. This study aims to develop a decision tool under uncertain and risky conditions for achieving sustainability in electronic waste (e-waste) recycling in circular economy. Prospect theory and its aspects are integrated with the sustainability risk assessment in e-waste recycling. In order to evaluate the irrationality and risk attitudes of decision makers in a risky and uncertain environment, the prospect theory-based TODIM (acronym in Portuguese for interactive and multicriteria decision-making, i.e. Tomada de Decisão Interativa Multicritério) method for a previous computer disassembly problem is used. Using prospect theory, the relationship between loss aversion, reference point, framing and two selves effect, and sustainability dimensions is presented with a sustainability risk assessment point of view. Further, tasks of computer disassembly processes are prioritized by considering risk factors. The results showed that random access memory modules, motherboard and power supply are the highest priority risks based on the evaluation of listed twelve sustainability risks. In this study, it is suggested that prospect theory is suitable for decisions under risk and uncertainty, and it is applicable to integrate sustainability risk assessment and prospect theory in order to fulfil the gap of knowledge.

循环经济中电子废物回收的可持续性风险评估

摘要

电子垃圾是对人类健康、环境和企业有害的概念,因此,风险评估对于消除或减少电子垃圾在循环经济中的负面影响至关重要。决策在电子废物回收的风险评估中起着重要作用。本研究旨在开发一种在不确定和风险条件下的决策工具,以实现循环经济中电子废物(电子废物)回收的可持续性。前景理论及其方面与电子废物回收的可持续性风险评估相结合。为了评估决策者在风险和不确定环境中的非理性和风险态度,基于前景理论的TODIM(葡萄牙语中交互式多准则决策的缩写,即 Tomada de Decisão Interativa Multicritério) 方法用于解决以前的计算机反汇编问题。运用前景理论,从可持续性风险评估的角度,提出了损失厌恶、参考点、框架和两个自我效应与可持续性维度之间的关系。此外,通过考虑风险因素对计算机拆卸过程的任务进行优先级排序。结果表明,基于对列出的十二个可持续性风险的评估,随机存取内存模块、主板和电源是最高优先级的风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。运用前景理论,从可持续性风险评估的角度,提出了损失厌恶、参考点、框架和两个自我效应与可持续性维度之间的关系。此外,通过考虑风险因素对计算机拆卸过程的任务进行优先级排序。结果表明,基于对列出的十二个可持续性风险的评估,随机存取内存模块、主板和电源是最高优先级的风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。运用前景理论,从可持续性风险评估的角度,提出了损失厌恶、参考点、框架和两个自我效应与可持续性维度之间的关系。此外,通过考虑风险因素对计算机拆卸过程的任务进行优先级排序。结果表明,基于对列出的十二个可持续性风险的评估,随机存取内存模块、主板和电源是最高优先级的风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。可持续性维度是从可持续性风险评估的角度提出的。此外,通过考虑风险因素对计算机拆卸过程的任务进行优先级排序。结果表明,基于对列出的十二个可持续性风险的评估,随机存取内存模块、主板和电源是最高优先级的风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。可持续性维度是从可持续性风险评估的角度提出的。此外,通过考虑风险因素对计算机拆卸过程的任务进行优先级排序。结果表明,基于对列出的十二个可持续性风险的评估,随机存取内存模块、主板和电源是最高优先级的风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。根据对列出的十二个可持续性风险的评估,主板和电源是最高优先级风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。根据对列出的十二个可持续性风险的评估,主板和电源是最高优先级风险。本研究提出前景理论适用于风险和不确定性下的决策,适用于将可持续性风险评估与前景理论相结合,以填补知识空白。
