The Viable System Model and Its Application to Complex Organizations

Stafford Beer’s Viable System Model is the best known of the many cybernetic models he constructed over a career spanning more than 50 years. He explored the necessary conditions for viability in any complex system whether an organism, an organization or a country. Although the model was first applied in his work in the steel industry, many further applications were made during his later work as a consultant. The best known of these was when he was invited by President Salvadore Allende of Chile in 1970 to model the social economy of that country. That experiment was brutally cut short in 1973 by the CIA assisted coup during which Allende was killed and Pinochet’s dictatorship installed. The model itself draws on mathematics, psychology, biology, neurophysiology, communication theory, anthropology and philosophy. It was first expressed in mathematical terms in ‘The Cybernetic Factory’; next it was described in neurophysiological terms in Brain of the firm; and finally according to logic and graphic presentation in Heart of Enterprise and Diagnosing the System for Organizations. This last version is the one that is most accessible. It enables people to address organizational issues in a way that skirts the usual categories and organization charts and gets down to the actual necessary functions, no matter who is performing them. With this model people can get a boost as they diagnose or design an organizations. One aspect is to discover what the organization’s critical variables are and to find or install the homeostats that will show that they are maintaining equilibrium. Within that context, the model will help you ascertain that the principle functions and communications channels are in place and can function effectively. A crucial aspect of the VSM is that it is recursive; that is that the same relationships can be traced from the shop floor to the corporation or from the village to the country. Two examples will be discussed: a small business and the Chilean work from the 1970s. It is hoped that this will encourage people to imagine a world that works much better than it does now and where management is not defeated by complexity. A version of this paper was delivered as the first Stafford Beer Memorial Lecture on July 8, 2007 at the World Multiconference on Systems, Cybernetics and Informatics in Orlando Florida.     

基于联合视角的项目支付问题及其模拟退火启发式算法

从合同双方的联合视角出发,研究项目支付进度问题。其中,支付与项目事件相联系,任务是合理地安排支付事件、活动执行模式及事件发生时间,以使合同双方的共同收益最大化并使二者都能接受相应的安排。在对问题进行界定的基础上,构建由两个子模型构成的优化模型。针对问题的强NP-hard属性,设计包含两个子模块的模拟退火启发式算法,并在随机生成的标准算例集合上对算法进行测试,结果表明,该算法是求解问题的有效算法。最后,用一个算例对研究进行说明,得到如下结论:如果合同双方均按自身偏好进行决策,那么将会导致一种双输的结果;如果他们能够相互合作和协调,那么都可从项目中获得更高的收益。本文的研究可以为合同双方关于项目支付进度安排的谈判提供决策支持。     

完善招投标工作与加强工程造价计价管理的探讨

工程量清单计价制的推行使工程造价计价的管理与招投标的关系更加紧密。本文针对推行《建筑工程工程量清单计价规范》后招投标工作可能遇到的问题，参照国际惯例、国内试运行的经验以及工作中的体会，阐述了在推行《建筑工程工程量清单计价规范》后做好招投标工作的对策和亟待配套的相关措施。     

基于进度优化的大型项目激励机制模型

在项目管理实践中,业主通常会设立激励机制以确保项目按期完成,而承包商则会根据业主设定的激励机制合理安排项目进度.本文讨论了大型项目的激励机制,研究了业主和承包商的决策问题,建立了以项目收益净现值最大化为目标函数的Stackelberg主从递阶决策模型.通过各子项目激励强度的设定对激励机制进行优化,协调业主和各承包商的利益关系,进而实现业主收益的最大化.     

美国能源发展战略的动向及其对我国的启示

2000～2001年席卷全美的能源危机．敲响了能源问题被忽视的警钟．为此，美国政府组织强大阵容，在大量调查的基础上，制定了美国预计到2020年的能源政策，之后美国国会又通过了能源法案。在我国能源供应市场化和国际化的进程中，美国能源发展战略的新动向给我国能源安全路径选择提供了重要启示。本文在分析其战略动向的基础上，结合我国实际，探讨了我国的能源发展战略。
