Non-centralized control for flow-based distribution networks: A game-theoretical insight

This paper solves a data-driven control problem for a flow-based distribution network with two objectives: a resource allocation and a fair distribution of costs. These objectives represent both cooperation and competition directions. It is proposed a solution that combines either a centralized or distributed cooperative game approach using the Shapley value to determine a proper partitioning of the system and a fair communication cost distribution. On the other hand, a decentralized non-cooperative game approach computing the Nash equilibrium is used to achieve the control objective of the resource allocation under a non-complete information topology. Furthermore, an invariant-set property is presented and the closed-loop system stability is analyzed for the non-cooperative game approach. Another contribution regarding the cooperative game approach is an alternative way to compute the Shapley value for the proposed specific characteristic function. Unlike the classical cooperative-games approach, which has a limited application due to the combinatorial explosion issues, the alternative method allows calculating the Shapley value in polynomial time and hence can be applied to large-scale problems.  相似文献   

分类(块)校对法之我见   总被引：1，自引：0，他引：1  

蔡建霞  刘荷芬 《编辑学报》2005,17(4):252-252

科技期刊中的专业术语很多,引用文献多,图表、公式复杂,所以,较之社科类期刊,校对工作费时费力[1].如何提高科技期刊校对时的纠错水平,把错误降到最少,除了应有较强的责任心外,还需要我们在实际工作中不断摸索新的校对方法和校对技巧.  相似文献

建立新型的编校关系与编校合作模式     

高健 《出版科学》2009,17(6):25-28

当今编校工作已发生深刻变化,编辑侧重选题策划、出版周期缩短等,造成文字加工粗疏,校对承担着编辑职责“后移”带来的巨大压力以及“校是非”的挑战,编校流程不顺畅甚至矛盾重重,编校质量打了折扣。必须对编校进行重新定位,加强编校沟通,协调编校关系,建立起新型的编校合作模式,使编校工序流畅有序,保证图书编校质量,缩减编校成本,才能适应激烈的市场竞争。  相似文献   

Proofreading as an index of crystallised intelligence     

Adrian Furnham 《教育心理学》2010,30(6):735-754

This paper reports on four studies that were all concerned with cognitive and non‐cognitive correlates of proofreading (PR) ability. A new, five‐minute PR test was devised and piloted. In the first pilot study (N = 191) it was correlated with a verbal reasoning test. In the second study (N = 103) PR scores were regressed onto measures of personality: approach to learning, general and fluid intelligence (verbal reasoning) as well as a test of general knowledge. All three cognitive ability measures were significant predictors of PR but when entered together, general knowledge alone remained significant and accounted for a third of the variance. The third study (N = 95) was similar, except it also included a measure of typical intellectual engagement. Fluid intelligence (verbal reasoning) and openness were the only significant predictors of PR. In the fourth study (N = 249) participants completed four tests: PR, fluid intelligence (verbal reasoning), vocabulary and spelling. PR was consistently correlated with verbal reasoning but more strongly correlated with measures of crystallised intelligence, namely general knowledge and vocabulary. Implications and limitations are considered.  相似文献
