Designing resilient biofuel supply chains that can withstand these risks while maintaining security and competitiveness has become a major concern and an urgent issue for enterprises. However, due to the lack of effective methods for quantifying and evaluating supply chain disruption risks, existing supply chain design approaches fail to adequately address the problem of mitigating such risks. To address this issue, this paper proposes an improved Node Disruption Impact Index with adjustable parameters, based on cost changes in the supply chain caused by disruptions at different nodes. This index enables the identification of nodes with varying risk levels and provides a means for evaluating disruption impact. The adjustable parameters can be tailored to meet the needs of supply chain enterprises, facilitating a trade-off between economic benefits and supply chain resilience. Furthermore, the paper applies the index to the fluctuation range of node uncertainties and develops a two-stage stochastic programming supply chain optimization model. This model incorporates a mechanism for addressing potential high disruption risks. By applying the model to a biofuel supply chain case in Guangdong Province, the results demonstrate that, when high-risk nodes are interrupted, the proposed model outperforms traditional models in terms of cost and market delivery rate. This confirms the effectiveness of the method in the optimization design of resilient supply chain.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 6","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results from Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy confirmed the successful synthesis of UiO-66 and illustrated the assembly of CS and PA onto UiO-66 through a self-assembly strategy. Thermogravimetric analysis in conjunction with cone calorimetry and Raman spectroscopy analyses indicated that incorporating biologically-based flame-retardant coating-modified CS/PA@UiO-66 and BN nanosheets could effectively increase the flame-retardant performance of epoxy composites.
