The circular economy (CE) is reasoned to organize complex systems supporting sustainable resilience by distinguishing between waste materials and economic growth. This is crucial to the electronic waste (e-waste) industry of developed countries, and e-waste operation management has become their top priority because e-waste contains toxic materials and valuable sources of elements. In the UK, although London Metropolitan city boasts an ambitious sustainable resilience target underlying the context of CE, practical implementation has yet to be feasible, with few investigations detailing if and how the existing target implications enable industrial and social-ecological sectors to continue their performance functionalities in the face of undesired disruptions. In this paper, a dynamic Bayesian Network (dynamic BN) approach is developed to address a range of potential risks. The existing London e-waste operation management is considered as an application of study for sustainable resilience development. Through the utilization of dynamic BN, a comprehensive analysis yields a Resilience Index (RI) of 0.5424, coupled with a StdDev of 0.01350. These metrics offer a profound insight into the intricate workings of a sustainable system and its capacity to swiftly rebound from unexpected shocks and disturbances. This newfound understanding equips policymakers with the knowledge needed to navigate the complexities of sustainable e-waste management effectively. The implications drawn from these in-depth analyses furnish policymakers with invaluable information, enabling them to make judicious decisions that advance the cause of sustainable e-waste management. The findings underscore that the absorptive capacity of a sustainable and resilient e-waste operation management system stands as the foremost defense mechanism against unforeseen challenges. Furthermore, it becomes evident that two pivotal factors, namely "diversifying the supply chain" and "enhancing supply chain transparency," play pivotal roles in augmenting the sustainability and resilience of e-waste operation management within the context of London's ambitious sustainability targets. These factors are instrumental in steering the trajectory of e-waste management towards a more sustainable and resilient future, aligning with London's aspirations for a greener and more eco-conscious future.
循环经济（CE）被认为是通过区分废料和经济增长来组织支持可持续恢复力的复杂系统。这对发达国家的电子垃圾（e-waste）行业至关重要，并且电子垃圾运营管理已成为其首要任务，因为电子垃圾含有有毒物质和有价值的元素来源。在英国，尽管伦敦市在循环经济背景下拥有雄心勃勃的可持续恢复力目标，但实际实施仍不可行，很少有调查详细说明现有的目标影响是否以及如何使工业和社会生态部门在面对意外干扰时继续其性能功能。在本文中，开发了一种动态贝叶斯网络（dynamic BN）方法来应对一系列潜在风险。现有的伦敦电子垃圾运营管理被视为可持续恢复力发展研究的一个应用。通过使用动态贝叶斯网络，全面分析得出弹性指数（RI）为0.5424，标准差为0.01350。这些指标为可持续系统的复杂运作及其从意外冲击和干扰中迅速反弹的能力提供了深刻见解。这一新认识为政策制定者提供了有效应对可持续电子垃圾管理复杂性所需的知识。这些深入分析得出的启示为政策制定者提供了宝贵信息，使他们能够做出明智决策，推动可持续电子垃圾管理事业的发展。研究结果强调，可持续且有恢复力的电子垃圾运营管理系统的吸收能力是抵御不可预见挑战的首要防御机制。此外，显而易见的是，“供应链多样化”和“提高供应链透明度”这两个关键因素在增强伦敦雄心勃勃的可持续发展目标背景下电子垃圾运营管理的可持续性和恢复力方面发挥着关键作用。这些因素有助于引导电子垃圾管理走向更可持续、更有恢复力的未来，符合伦敦对更绿色、更具生态意识未来的期望。
