复杂系统质量生存决策的模型研究

在复杂经济系统的生存决策模型的基础上加入期望约束,提出并建立了一个基于资源、惯性和期望约束的质量生存决策的三维基本模型.由于决策系统的质量生存性由质量生存核维持,但在一般情况下得不到质量生存核的解析解,因此对其大小、形状、位置进行了理论分析,并根据理论分析结果,按照不同质量生存特性将三维决策空间进行了定性区域划分,最后用一个仿真实例进行了简单验证.

群决策中基于语言信息处理的一种理想点法

针对具有自然语言评价信息的多指标群决策问题,提出了一种基于语言信息处理的理想点法。该方法是采用近年来最新发展的LWD算子和LOWA算子对自然语言符号进行处理和运算,通过计算每个方案与正负理想点间的距离,最终确定最优方案,使该方案最贴近正理想点和最远离负理想点。最后给出了一个算例。

冯延巳对词的抒情模式的建构及其影响

词的雅化与文人化最关键的一步是精神与品格的雅化与文人化。要做到这一点,就必须在原本内容浮泛、娱人为主的词中注入士大夫知识分子的“情”,并使之纳入符合士大夫知识分子审美情趣的抒情模式和风格中。这个变革工作是由冯延巳来首倡和推行的。冯延已最大的成就就是在词中引入了诗歌赋比兴的传统手法,使词有了意境,并因之确立了词思深语丽、含蓄蕴藉的婉约派抒情风格,从而开了北宋一代词风;     

企业经理风险决策行为的实证研究

本文报告的两项研究系统深入地探讨了中国企业经理的风险决策行为。在研究一中,214名企业经理填答了效用测量表;在研究二中,82名企业经理填答风险决策情景模拟表。结果发现,个人特征(如性别、职位、所在企业的性质与规模等)、决策任务特征(如结果值的符号与大小)以及决策环境特征(如企业文化、企业经营状况、上司的风险态度等)均是影响企业经理风险决策行为的关键变量。本文为建立风险决策行为的理论或模型提供了基本的参考资料。

The case of post-acquisition integration design decisions

In a multi-method study that examined post-acquisition integration design decisions, managers were found to have poor insight into the values underlying their decision making. This lack of insight was not found to be moderated by increased levels of experience with acquisition decision making, and its effects were reflected in post-acquisition performance.     

Assessing Engineering Resilience for Systems with Multiple Performance Measures

Recently, efforts to model and assess a system's resilience to disruptions due to environmental and adversarial threats have increased substantially. Researchers have investigated resilience in many disciplines, including sociology, psychology, computer networks, and engineering systems, to name a few. When assessing engineering system resilience, the resilience assessment typically considers a single performance measure, a disruption, a loss of performance, the time required to recover, or a combination of these elements. We define and use a resilient engineered system definition that separates system resilience into platform and mission resilience. Most complex systems have multiple performance measures; this research proposes using multiple objective decision analysis to assess system resilience for systems with multiple performance measures using two distinct methods. The first method quantifies platform resilience and includes resilience and other “ilities” directly in the value hierarchy, while the second method quantifies mission resilience and uses the “ilities” in the calculation of the expected mission performance for every performance measure in the value hierarchy. We illustrate the mission resilience method using a transportation systems‐of‐systems network with varying levels of resilience due to the level of connectivity and autonomy of the vehicles and platform resilience by using a notional military example. Our analysis found that it is necessary to quantify performance in context with specific mission(s) and scenario(s) under specific threat(s) and then use modeling and simulation to help determine the resilience of a system for a given set of conditions. The example demonstrates how incorporating system mission resilience can improve performance for some performance measures while negatively affecting others.
