为解决应急物流智能协作面临的异构信息融合与知识管理难题,以有效知识应用为目标,利用业务模型与本体模型对组成构件上的相关性进行映射,并根据系统控制与实体行为约束所需的业务推理规则,设计了3种模块之间的关系与四阶段转换步骤,形成了业务模型驱动的本体表示方法。以该方法为基础,结合应急物流领域需求,建立了由概念集合、概念属性、语义约束、推理规则等要素组成的应急物流本体模型。通过应急配送路径选择案例,自动推理得到可替代邻近点以完成配送路径求解。结果表明,应急物流本体模型及其应用实现了异构信息的本体融合,消除了以关键词匹配为基础的常规检索失效现象,满足了最小路径算法的执行条件,为应急物流决策模型及算法应用提供了知识层面的支持。
為解決應急物流智能協作麵臨的異構信息融閤與知識管理難題,以有效知識應用為目標,利用業務模型與本體模型對組成構件上的相關性進行映射,併根據繫統控製與實體行為約束所需的業務推理規則,設計瞭3種模塊之間的關繫與四階段轉換步驟,形成瞭業務模型驅動的本體錶示方法。以該方法為基礎,結閤應急物流領域需求,建立瞭由概唸集閤、概唸屬性、語義約束、推理規則等要素組成的應急物流本體模型。通過應急配送路徑選擇案例,自動推理得到可替代鄰近點以完成配送路徑求解。結果錶明,應急物流本體模型及其應用實現瞭異構信息的本體融閤,消除瞭以關鍵詞匹配為基礎的常規檢索失效現象,滿足瞭最小路徑算法的執行條件,為應急物流決策模型及算法應用提供瞭知識層麵的支持。

To solve the problem of heterogeneous information integration and knowledge management in the emergency logistics intelligent collaboration,aiming at the effective knowledge application,an ontology modeling method was proposed by utilizing the internal mapping of components and the business inference rules between business model and ontology model,involving relations among three modules and a four-step transformation process. Based on the suggested modeling method, an emergency logistics ontology model composed of concept aggregation,concept attribute,semantic restriction,and reasoning rules was constructed. As a case study,an emergency distribution routing problem was addressed by implementing the ontology model and reasoning out the neighboring alternative nodes. The result shows that the proposed ontology model and its application can achieve the heterogeneous information integration with ontology,eliminating the conventional retrieval invalid phenomenon,satisfying the conditions of the shortest path routing,and providing the knowledge base for the emergency logistics decision-making model and its algorithm application.
