我国非国家组织药品集中采购模式比较

目的比较分析我国各省市的药品集中采购方案及相关政策,探讨各地非国家组织药品集中采购模式的特点。方法围绕采购内容、采购规则等比较分析各地的非国家组织药品集中采购模式的特点,以及采购内容、采购环境、采购规则之间的内在关系。结果我国目前的非国家组织药品集中采购模式可划分为药品集中采购组织(group purchasing organization,GPO)、非过评仿制药带量采购、专项药品带量采购、带量议价以及分类采购框架下的带量采购5种。我国非国家组织药品集中采购的特点是分品种、分批次,以政府主导为主,执行机构主要为医疗保障局。结论目前,各地的非国家组织药品集中采购仅覆盖了部分品种的药品,对非过评仿制药进行集中采购是未来的重要趋势,建立公平、科学的质量分组规则是非国家组织药品集中采购亟待解决的重要技术问题。

Algorithms for Increasing of the Effectiveness of the Making Decisions by Intelligent Fuzzy Systems

There are considered rule-based intelligent systems using fuzzy inference. Comparative analysis of different approaches and algorithms of making decisions on the base of fuzzy logic is given. Using of the parallel calculations can reduce the time of making decision in case of large-scale systems. Effectiveness of parallel calculations depends on the grouping of the rules and variables. Building of the graph of the dependence of the rules and the graph of dependence of the linguistic variables are suggested. On the base of the developed groups of rules and defuzzification of the linguistic variables we suggest to reduce the time of making decision and therefore to increase the effectiveness of the decision making with using of parallel calculations for each group.

THE SUFFICIENT AND NECESSARY CONDITION OF THE MAJOR STOCHASTIC PREFERENCE RULE IN GROUP DECISION MAKING

Group decision making problem with stochastic preference is investigated. The authors present four rational conditions for testing group stochastic preference rule, and prove that the com- bination of these four rational conditions is the sufficient and necessary condition of major stochastic preference rule for group stochastic preference rule.
