“…In addition, they presented examples of managers' contributions to healthcare system resilience in longitudinal intervention studies. Taherkhani et al (2022) developed a methodology to assess the efficacy of various substation disaster recovery plans to improve the electrical resilience of healthcare systems, thereby improving system recoverability after earthquakes. Wiig et al (2020) claimed that despite the differences in definitions of resilience, some of the same resilience processes exist.…”

The concept of resilience is complex and interdisciplinary, with various theories, models and definitions of resilience (Chowdhury and Quaddus, 2016;Taherkhani et al, 2022). Regarding the definition of resilience, there are sociological studies of recovery from disaster events (Johnson et al, 2013), psychological explanations of individual human responses to stress (Corbaz-Kurth et al, 2022) and engineering perspectives on safety science (Wiig et al, 2020).…”

PurposeThe purpose of this paper is to examine the impact of two typical relationship management approaches (trust relationship with suppliers and reciprocity) on manufacturer resilience in the context of the COVID-19 crisis. Moreover, this paper aims to deepen the understanding of environmental uncertainty's moderating effect on the association between the trust relationship with suppliers (TRS) and reciprocity.Design/methodology/approachStructural equation modeling has been used to test the hypotheses on 361 Chinese manufacturing firms' managers and independent directors during the COVID-19 crisis.FindingsThe results reveal that reciprocity positively enhances three dimensions of manufacturer resilience, namely, preparedness, responsiveness and recovery capability. Reciprocity positively mediates the relationships between TRS and preparedness, responsiveness and recovery capability. Moreover, environmental uncertainty moderates the association between TRS and reciprocity.Practical implicationsThis study highlights the critical role of reciprocity, the relational governance approach, in enhancing manufacturer resilience in practice. This paper suggests that during emergencies such as the COVID-19 pandemic, managers should adopt trust and reciprocity in supplier relationship governance to strengthen the resilience of manufacturing companies and adapt effective strategies according to the environment.Originality/valueThis study is unique in developing new scales of manufacturer resilience through interviews and surveys with Chinese manufacturers and theoretical research. Based on the social capital theory and social exchange theory, this study shed light on the role of trust and reciprocity. It also bridges relational governance theory with the literature on manufacturing firm resilience literature to help manufacturers better understand the transdisciplinary links between relationship management and resilient operations in emergencies.

“…There are currently 687 operational microgrids in the US, off-grid or grid-connected, with a total capacity of 4.4 GW supporting diverse communities, including universities, hospitals, and military bases, among others [6]. The demand for microgrids continues to rise as entities and communities seek to use microgrids as supplementary power sources for enhanced energy resilience and reliability [8][9][10]. Microgrids also offer promising sustainability benefits as renewable energy technologies become increasingly feasible and affordable [11].…”

Microgrid implementation often lacks economic and environmental efficiencies due to sub-optimal configuration and operation. The current study aims to explore the optimal configuration and operational strategies for a microgrid system with maximum life cycle economic and environmental co-benefits. This study was inspired by a real microgrid optimization need for Shoals Marine Laboratory, a seasonal marine teaching and research field station on Appledore Island, Maine. A system dynamic model was developed to simulate the microgrid operation, and a multi-criteria analysis was performed based on diesel electricity generation, equivalent annual costs, and carbon footprint under various system sizing and operation scenarios. This study found that an effective battery capacity of 120–165 kWh (400–550 kWh actual with 30% depth of discharge) and a solar capacity of 85–105 kW can effectively minimize all three objectives under an average daily demand of 265 kWh during the study period. Additionally, implementing an alternative system operation strategy can lead to a 12% reduction in diesel electricity generation.
