This paper describes the process that was followed at the Colombian National Audit Office, during 3.5 years, to develop new auditing practices, called second-order auditing. The purpose of the second-order control is to detect possible faults in the internal control mechanisms of the audited entities. General and particular models for second-order audit are presented, along with a method to carry out this type of auditing. Finally, a particular application of second-order auditing carried out in a Colombian national institution is presented.  相似文献

在HLA仿真框架下,仿真资源的重用是一件意义重大的事情,这也是FEDEP过程要着重解决的问题。然而实际工作中,重用SOM构建FOM的工作经常被不同SOM中类的继承关系造成的语义上的歧义所困扰,究其原因,没有一个统一的模型库视图是其根源。为此,提出一种新的模型库分层构建的方法,这种方法按照对象之间的继承和组合关系把对象模型库分成相互联系的两层,它使得模型库可以自由扩展,避免库中信息之间语义上歧义的出现。  相似文献

海尔集团整合营销战略   总被引:2,自引:0,他引:2  
回顾营销思想演变过程,指出西方整舍营销传播理念虽然被广泛接受,但并不能充分支持营销实践经历了从大规模营销到整合营销的转变。整舍营销传播是一个不断完善的过程,论文提出的整合营销战略体现了动态发展阶段性的特点,这种整合营销战略是关系营销和后工业制造特点相结舍的战略营销模式。文章通过分析海尔集团整合营销战略的实践和经验:组织结构和营销流程再造、客户关系管理和客户、产品、型号三种经理围绕订单实现的运作耦合,指出整合营销战略对中因家电等相关制造企业的营销管理和发展具有重要借鉴意义。  相似文献

Platoon formation of highway vehicles is a critical foundation for autonomous or semiautonomous vehicle control for enhanced safety,improved highway utility,increased fuel economy,and reduced emission toward intelligent transportation systems.Platoon control encounters great challenges from vehicle control,communications,team coordination,and uncertainties.This paper introduces a new method for coordinated control of platoons by using integrated network consensus decisions and vehicle control.To achieve suitable coordination of the team vehicles based on terrain and environmental conditions,the emerging technology of network consensus control is modified to a weighted and constrained consensus-seeking framework.Algorithms are introduced and their convergence properties are established.The methodology employs neighborhood information through on-board sensors and V2 V or V2 I communications,but achieves global coordination of the entire platoon.The ability of the methods in terms of robustness,disturbance rejection,noise attenuation,and cyber-physical interaction is analyzed and demonstrated with simulated case studies.  相似文献

This paper presents a new methodological approach for the synthesis of a neuro-fuzzy controller, using an on-line learning procedure. A simple algebraic formulation of a Sugeno fuzzy inference system that ensures a coherent universe of discourse, making easy its interpretation by a human being, is proposed and implemented in the case of the control of a bioreactor, which is considered as a complex non linear process.  相似文献

1. Introduction Fuzzy controllers have interesting characteristics, principally concerning their robustness and their ability to integrate human knowledge in the design of control systems, allowing to a human operator to interpret, at every time, the action of the control system. However, the synthesis of a fuzzy controller, giving the controlled process a specified behaviour, is not an evident thing. Indeed, tuning the parameters of a fuzzy controller is often achieved by a succession of tria…  相似文献

审计评价的Agent系统问题,就是行为审计博弈方的最优对策问题,即审计服务双方对其收益最大化的管理与优化.因此,风险因素在审计收益管理中有着重要影响,当把风险因素引入审计评价系统,并设定评价为Agent模式后,审计资产所有者风险份额的相对控制会从外部推动审计服务与评价效能的提升,内部会启动提高审计资产所有者效率的动力机制,从而提高了评价系统活力.通过审计评价系统的Agent模型与优化调控审计绩效评价管理方向,有助于促进审计绩效的持续改善,更好地促进审计服务创新发展.  相似文献

The paper summarizes recent work on organizations, artificial intelligence systems, human-computer interaction, etc., which emphasizes thesituated, distributed, andfluid nature of social systems. This contrasts with the traditional way of writing and thinking about social systems which sees them as disembodied, ideal, formal notions of thought. The implications of this new view of systems for social actors, information, knowledge, and technology are discussed. The literature reviewed offers a new way of talking about systems and their practices.  相似文献

由于决策实体控制战场作战平台资源实体,通过平台资源实体执行作战任务,作战平台资源实体在任务上的聚集导致决策实体间需要复杂的交互协作与交流,兵力编成需要为任务的执行创造良好的交互结构.基于任务执行的兵力编成包括两方面的内容:一是指控决策结点间的协作关系;二是指控决策结点间的指挥关系.本文通过决策实体对平台控制的矢量以及矢量距离的定义,提出了指控决策结点间协作关系优化设计的聚类算法,在聚类过程中通过设置不同的决策实体数量、决策实体能力以及内部协作与外部协作权值,分析比较了不同设置情况下所产生的兵力编成的协作关系与决策者的协作负载.  相似文献

Grounded in social constructivism within an action research framework, this paper locates oral assessment within situated learning and focuses on the construction and assessment of knowledge within communities of practice. This study found that by simulating situations for undergraduate learners to familiarize them with the discourse practices before they are expected to interact on a more professional level within communities of practice, oral assessment enables exposure to the cultural models and the sociocultural groups that can socialize them into these. It is recommended that these experiences be guided by their educators and more capable peers so that learning can be scaffolded.  相似文献

A typology of power is presented. The typology guides researchers/practitioners to the main concerns currently debated about power and its abuses. Possible ways of managing organisational issues explicitly dealing with power and abuses are explored. The typology forms threearenas of discourse to make this possible: structuralism, intersubjective decision making, and might-right management. Structuralism deals with issues surrounding organisational design and process design. Intersubjective decision making deals with issues surrounding processes of debate. Might-right management deals with issues surrounding disempowering social practices that impact on designing and debating. The arenas of discourse suggest ways, that differ, of understanding and managing a range of issues related to the operation of power. This is part of a wider project called Diversity Management, which in turn is part of Critical Systems Thinking.  相似文献

This paper explores some of the unilluminated or less explicit aspects of issues faced by those using systems approaches in real-world problem situations. The paper contends that discourse on systems approaches tends to be dominated by rational logical aspects of methodology, though other aspects of the intervention process, such as political dimensions of legitimacy, have become more important in the last 10–15 years. Unsurprisingly the discourse has been different for different methods. Method has been largely invisible in the hard systems area (or at least relatively little discussed), and although it has been the subject of much debate in the soft systems area, the debate has been nonetheless narrowly defined. It is narrowly defined in its relative neglect of process aspects for conducting a systems study. Since the nature of these processes (for example, the client/consultant relation) changes from hard systems to soft systems to critical systems in a way that makes social process progressively a more important dimension of each approach, this aspect has featured more in discourse on critical systems, but in general it remains a curious area of neglect. There is increasing interest in this area, and some signs that relevant theory and practice from closely related domains is being accessed to strengthen these approaches. This paper attempts to make a contribution by outlining and discussing some areas that could usefully complement existing systems approaches. The paper considers the following areas: (a) client relations, (b) analyst role, (c) language and communication, (d) group processes, (e) culture (and rationalities), (f) information gathering techniques and processes, and (g) change management or implementation. The paper draws on experiences of systems practices in the literature, interviews with systems practitioners, and writings in related areas. The paper ends by discussing some of the implications of these issues for the development of well-rounded systems approaches.  相似文献
