基于过程组件的物流管理系统模型设计及分析

物流管理系统是工作流管理系统的重要组成部分，是企业经营过程的核心，借鉴组合Petri网的思想，在组件技术和分布式对象技术的基础上，提出了基于过程组件的物流管理系统的层次结构模型，该模型中，可复用的中等粒度的过程组件通过内部建立数据流和控制规则库。屏蔽了精细粒度的原子性对象之间的调用关系，提高了组件的重用性，提出了重组策略，给出了该模型的Petri网映射模型。为模型的性质分析提供了可靠的分析工具。

论博尔赫斯小说《女海盗金寡妇》中郑一嫂的故事流传

通过对博尔赫斯小说《女海盗金寡妇》故事载体的写作背景研究,可以确认女海盗郑一嫂的故事并非博尔赫斯的完全杜撰。进一步进行书面渊源的考证可以发现：郑一嫂的故事来源于菲利普.戈斯的《海盗史》对中国清代史料《靖海氛记》的间接转述。郑一嫂的故事流传经历了翻译、改编和作者的再创作的过程。通过对文本的形成变化过程的细节比较可以看出,不同作者的写作目的的变化应该是故事情节变化的直接原因;同时,上一位作者的取舍也在一定程度上影响到了后人的创作。

Application of Teleonic Principles in the Search for Systemic Causes of Accidents in Anesthesia

Safety of patients in anesthesia has always been one of the major concerns of the anesthetist. It is clear from studies of safety in general that many accidents and critical incidents occur as the result of latent systemic failures to which a great number of factors contribute (Reason, 1990). An ideal way to approach this problem would be within a systemic framework, such as teleonics, developed by Járos and his co-workers (Cloete, 1999; Járos and Cloete, 1987, 1993). In this framework the events and procedures in anesthesia are considered to be part of a very complex network of process systems (teleons). It is postulated that teleonic uncertainty (telentropy) in this complex network is a factor that might lead to accidents. In a previous paper presented to the World Congress at Toronto in 2000, the principles of teleonics were described in a mathematico symbolic way (Horváth et al., 2000). This paper contains selected examples of application of these principles to the identification of possible systemic causes of accidents in anesthesia.
