基于语义X列表的可重构药品价值链知识模型

摘要

为减少药品价值链系统价值载体的“价值－价格偏离”，实现系统形式化知识表达与优化重构，从药品价格－价值“形成、流动、传递与实现”的视角，构建了药品价值链系统闭环结构模型；基于该模型，运用S-BOX理论分别将系统结构与运行机理转化为本体结构列表和语义推理规则，构建了可重构药品价值链系统知识模型。推理算例实验表明，本模型能有效计算不同药品价值链结构下价值载体在原料采购、制造、批发、零售等各价值链环节的“价值－价格偏离量”，进而实现价值链系统优化重构，可为抑制药品价格过高提供理论支持。%To reduce the“Deviation between Price and Value (DPV)”of the value carriers of the medical value chains,and to achieve formal knowledge expressing and reconstructing,from the view of value“forming-flowing-obtaining-realizing”processes,a closed loop model is constructed for analyzing the medi-cal value chain system. Based on this model and S-BOX model,the medical value chain system structures and operation mechanisms are respectively transformed into ontology structure bills and semantic rules,and then the S-BOX based reconfigurable medical value chain system knowledge model is constructed. Further-more,the reasoning results denote that the DPVs of medical value chain nodes can be effectively calculat-ed. And then with the DPVs,the value chains can be improved and reconstructed for controlling the phar-maceutical price intelligent.
