We explore problems involving the measurement of the performance of a system. We outline two systemic approaches that have come from different epistemological positions: one from the interpretivist paradigm (soft systems methodology) and the other from the cybernetic paradigm (viable systems model). These two systemic methodologies that have tackled problems involving performance measurement are considered and discussed: (a) Checkland’s systems ideas of ‘managing and controlling’ a system throughout a set of three measures of performance: efficacy, efficiency and effectiveness; and (b) Beer’s concepts of Actuality, Capability, Potentiality of the firm and his claims that the performance of a system needs to be quantifiable and resumed on ‘pure’ numbers which should reflect the survivability of the firm. A parallel is drawn between the two approaches concluding that although the paradigms underpinning them are in some way different, the practicalities of these approaches to control, measure and improve the performance of a system are very similar. A case involving the measurement of a proposed research strategic plan for a Manchester Metropolitan University Business School’s department is used to illustrate the systemic approaches.  相似文献

复杂性范式:一种新的科学世界观   总被引:2,自引:0,他引:2  
复杂性范式是随着复杂性科学的兴起而形成的一种科学新范式,它具有丰富的内涵,在本体论、认识论和方法论诸多方面都与传统科学范式相区别,并在许多领域逐渐取代传统科学范式。科学范式的复杂性转向正在掀起一场新的科学革命,并引起了科学世界观的变革。  相似文献

广义信息序量范式建构初步   总被引:2,自引:0,他引:2  
广义信息的序量符号范式将潜在信息、无序的物质能量、显在信息符号表示为:0(1,0)、0(0,1)、1(1,1),并作为符号范式体系的初始框架。序量是信息实际表现的有序度,各种信息系统序量的定义,是建构广义信息符号范式体系的重要步骤。普遍的序量范式,将多倍、多层次系统的序量表达为基层、基本系统序量的一定运算结果。以序量范式表述广义信息相互作用规律,具有凸现本质的优点。  相似文献

This short paper introduces a special issue of Systemic Practice and Action Research on new developments in Chinese systems practice. It focuses on the recent history of systems thinking in China, describing a paradigm shift that is currently taking place from an "objectivist" to a more pluralistic stance. Details are provided of the Hull–Beijing research program, which has contributed to this paradigm shift. In one way or another, all the papers in this special issue can be seen as having a connection with this research program.  相似文献

This paper presents an outline of an Oriental systems methodology: the Wuli Shili Renli approach (WSR). The basic theme of WSR contends that wuli (regularities in objective existence), shili (ways of seeing and doing), and renli (patterns underlying human relations) constitute a differentiated whole that conditions systems projects. WSR suggests that we should design and employ appropriate methods to address and tackle wuli shili and renli elements in a theoretically informed and systemic way. The background, philosophy, process, principles, and some practical applications of the methodology are preliminarily outlined.  相似文献

Soft System Dynamics Methodology (SSDM), a systemic methodology product of the combination of two widely used systems-based methodologies from two different systems thinking paradigms, Systems Dynamics (SD) and Soft Systems Methodology (SSM), is presented. The paper argues that by combining some of SD and SSM stages, within the intellectual framework proposed by SSDM, a methodology developed by one of the authors1 much can be gained in a systemic intervention to tackle complex social problematic situations. A framework for comparing the ontological, epistemological and methodological principles of SD, SSM and SSDM is proposed and the synthesizing and dialectical role of SSDM is advanced. The 10 stages of SSDM are outlined and illustrated by an application on a small Peruvian company; and a set of conclusions and points for further research are discussed.  相似文献

This paper is about the Wuli, Shili, Renli (WSR) systems methodology. An important concept within this, Renli, has been developed from Confucian philosophy to clarify to Chinese researchers the necessity of dealing with human relations in systems practice. At present, the only formal means of operationalizing Renli that people are exploring in China is to import from the West methods for organizing debate. However, the concept of Renli suggests that more is needed than methods alone. In particular, facilitation skills are required. It is argued that the development of facilitation skills can be enhanced if researchers can gain both theoretical and practical knowledge of group dynamics, and engage in activities of self-reflection to look at, and alter, their own roles in these dynamics and the wider sociopolitical system. There are therefore three aspects to Renli: the use of systems methods for organizing debate, the acquisition of facilitation skills, and self-reflection geared toward the development of facilitation skills and enhanced critical awareness of the politics of intervention.  相似文献

研究了两家竞争性制造企业面临自我节能和节能效益分享两种节能方式如何选择最优节能方式问题.首先建立两家制造企业相互对称的多阶段博弈模型,分析制造企业节能方式选择的均衡策略.结果表明存在两个对称的纳什均衡,当节能服务公司与制造企业的投资成本系数比率较小时,制造企业均应选择后者;反之,制造企业均应选择前者.之后将基本模型分别拓展到两家制造企业的投资成本系数不对称、初始能效不对称和分享期小于节能系统生命周期三种情形,进一步揭示了三种情形下制造企业节能方式选择的均衡策略.有意思的是,研究结果表明,在前述四种情形下两家制造企业的竞争强度均不会对制造企业节能方式选择均衡策略产生影响.  相似文献

The authors discuss the unbalanced two-way ANOVA model under heteroscedasticity. By taking the generalized approach, the authors derive the generalized p-values for testing the equality of fixed effects and the generalized confidence regions for these effects. The authors also provide their frequentist properties in large-sample cases. Simulation studies show that the generalized confidence regions have good coverage probabilities.  相似文献

This paper is written from the perspective of a practitioner-researcher coming to terms with methodologically or theoretically pluralist practice. Common depictions of the relationship between the hard and soft paradigms are discussed, including the influence of the problem of paradigmatic incommensurability. The consequences of different ways in which this relationship is depicted are examined, in light of various perspectives on the relationship of Critical Systems Thinking to these paradigms. Alternative models of this relationship are provided, followed by discussion of how these models can be extended to combinations of other paradigms in different contexts.  相似文献

顾客价值作为一种社会活动,它的多样性和主观动态特征导致了企业管理者在识别和选择顾客价值过程中遇到了很大的困难,这个困难促使本文从社会理论和系统科学的视域来重新考察了顾客价值这个概念的社会特征。根据这个特征本文采用了社会理论研究领域的诠释主义和功能主义两种范式来探讨对顾客价值的理解并在此基础上用软系统方法论构建出识别和选择顾客价值的系统方法论  相似文献

We study a single-server queueing system with state-dependent arrivals and general service distribution, or simply M(n)/G/1/K, where the server follows an N policy and takes multiple vacations when the system is empty. We provide a recursive algorithm using the supplementary variable technique to numerically compute the stationary queue length distribution of the system. The only input requirements are the Laplace-Stieltjes transforms of the service time distribution and the vacation time distribution, and the state-dependent arrival rate. The computational complexity of the algorithm is O(K^3).  相似文献

“系统科学”不同于“复杂性科学”,但由于其兴起背景和演化发展过程、研究对象以及指导范式等因素上的相近性,它们实质上又是相互融合的,是易于混淆的两种提法。对它们进行细致的区分是进一步了解系统科学与系统哲学研究领域的必要过程。  相似文献

理性行为理论认为,意愿是行为的有效预测变量;但企业社会责任相关研究表明,消费者的购买意愿与购买行为之间存在着巨大的差距。为了探究消费者响应企业社会责任行为对购买意愿的影响,并进而对购买行为的影响,以及购买意愿与购买行为之间的差距,构建了一个包含企业社会责任、购买意愿、购买行为、主动性人格与效能感的研究框架,通过情景化的自我报告问卷调查方法对研究框架进行了检验。研究结果表明:① 消费者一般会积极响应企业社会责任行为,其购买意愿部分中介企业社会责任与实际购买行为之间的关系;② 消费者由企业社会责任产生的购买意愿与购买行为之间存在较大的差距,企业社会责任可以解释25%的购买意愿,却只能解释20%的购买行为;③ 消费者主动性人格或效能感水平较高时,购买意愿对企业社会责任与购买行为之间关系的中介作用更强,可以有效减小伦理消费的意向-行为差距。  相似文献
