认知、架构与运行框架下应急物资供给的知识服务研究OA

[Purpose/significance]To address the challenges in matching supply-demand information within the emergency material supply domain,this study constructs a knowledge service framework from three dimensions cognition,architecture,and operation to enhance the agility of emergency response and the resilience of supply chains.[Method/[process]A cognition-centered knowledge service framework is proposed for the emergency material supply field,encompassing five dimensions:scenario,approach,structure,perspective,and model.Subsequently,a system architecture is developed focusing on three aspects:emergency data integration,knowledge-driven supply,and emergency scenario perception.The operationalization of the proposed knowledge service is explored in terms of its logic,mechanisms,and patterns.[Result/[conclusion]The constructed knowledge service framework effectively supports the association and transmission of multi-stage cascading knowledge by refining data perception granularity,structuring complex knowledge networks,and achieving seman-tic matching of supply and demand.It provides methodological and platform-based support for addressing supply-demand imbalances,enhancing supply chain resilience,and balancing response agility with supply flexibility.
