Abstract

[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 semantic 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.
