基模生成集分析的矩阵算法及在人力资源管理中的应用

针对学习型组织理论的系统思考的基模分析技术,提出一个确定复杂系统的基模生成集和对新管理措施进行反馈绩效分析的矩阵算法.此算法是将系统动力学的流率基本入树模型转化为对角置零枝向量矩阵,将枝向量矩阵分解,再作矩阵乘法.然后,用一个管理案例说明了该算法的实际价值,即运用此方法,对中国企业现阶段普遍实行的绩效等级薪酬人力资源管理方法进行研究,揭示了在人力资源管理中引入绩效等级薪酬激励机制后产生的增长上限系统结构,证明了此管理对内部员工和吸引外系统员工流入具有很好的激励作用,同时证明此管理机制增加了组织成本,产生对组织绩效的制约作用,从而揭示出企业人力资源绩效管理中的增长上限系统结构.     

专才还是通才?组织成员知识基础对创新绩效的影响

基于多主体仿真方法,构建了成员知识基础对创新绩效影响的动态仿真模型,分析了成员知识深度、知识宽度和知识交叠度对创新绩效的内在作用机理,解答了组织应该选择什么样的人、以及不同的人如何影响组织创新这两个重要问题。研究结果表明,知识宽度对创新绩效有积极效应,而知识深度的效应依赖于知识宽度与知识交叠度的交互影响。其中,知识宽度较低时,知识深度存在消极影响。知识宽度较高时,知识深度对创新绩效存在倒U型影响。知识宽度中等时,成员所拥有的优势知识是否重复至关重要。当优势知识均匀分布时,知识深度呈现积极效应;当优势知识高度重复时,不同领域的知识难以被融会贯通,知识深度的积极效应转变成消极效应。总体来说,兼具知识宽度和知识深度的T型人才最有利于提高创新绩效。此外,在专业型人才队伍中适当引入通用型人才,能够在多数情况下保证组织的最优表现。     

成员间互动对团队绩效影响研究:基于和谐管理理论的视角

团队已成为组织中重要的工作方式之一，已有的研究表明团队成员间的互动对团队绩效具有显著影响。但由于成员间交互的动态性、非线性以及成员行为的差异等特点，使得成员互动与团队绩效之间关系的考察成为一大难题。本文基于和谐管理理论的基本思想，将成员交互模式与成员策略变化规则按照和、谐划分为四种交互类型，并利用拓展的复杂系统模型—NK模型，考察四种互动类型对团队绩效的影响。研究结论将为和谐管理理论提供仿真验证并为实践中的团队管理与绩效考评提供参考。     

基于多Agent仿真的双元创新平衡与组织绩效关系研究

运用多主体仿真方法,探讨了双元创新平衡对组织绩效的作用机理,并且检验了个体间模仿学习速度、任务复杂度、人员流动、环境扰动等情境因素与双元创新平衡对组织绩效的交互影响。仿真实验的结果表明,当组织处于稳定环境下,任务复杂程度适中,并且个体间模仿学习速度中等时,双元创新平衡参数与组织绩效间呈现倒U型的影响关系;当任务过于复杂或者过于简单时,任务本身的特性削弱了双元创新平衡参数对组织绩效的影响,不同平衡模式对应的组织绩效没有明显的差距;当个体间模仿学习速度比较慢时,增强了组织的探索性,此时具有利用式创新倾向的组织可以更好地提升组织绩效水平。但当个体间模仿学习速度过快时,组织更多的倾向探索式创新对组织绩效的提升更有利;当组织存在人员流动和外部环境扰动时,更多的利用式创新可以提升组织对现有知识进行重组和整合的能力,从而更好地适应环境的动态变化。     

民企家长型领导、组织承诺与组织绩效的关系研究

以广东、广西68家民营企业的159名管理者及员工的调查结果为样本,实证分析了民企家长型领导、组织承诺与组织绩效的关系.研究发现:家长型领导行为中德行领导对组织承诺及组织绩效具有较大程度的影响,仁慈领导能够有效地促进员工组织承诺的提升并改善组织绩效,而威权领导则不利于员工组织承诺的提升.组织承诺在德行领导和仁慈领导与组织绩效的关系中有着积极的中介作用,在威权领导与组织绩效间的关系不明确.     

社会资本视角下的咨询网络演化研究

针对当前社会网络理论中静态结构主义的研究局限,本文基于过程的观点,将知识转移分为转移对象的搜索与对转移条件的判断两个过程,并从社会资本的三个分析维度建立了个体在知识转移过程中的行为模型,并基于此行为模型设计仿真实验,考察了涌现出来的咨询网络的结构特征,以及群体绩效的变化.实验结果表明,群体绩效与关系衰减系数以及成员的认知阈值正相关,咨询网络的集聚系数与衰减函数负相关,与成员的认知阈值正相关.研究结论将为交互式记忆系统及组织中know-who知识对群体绩效的影响提供有益的参考.     

基于投影寻踪模型的企业绩效评价研究

针对现有企业绩效研究主要以静态评价为主的现状,本文采用投影寻踪模型对企业绩效进行时序动态评价.鉴于该模型求解属于复杂的非线性优化问题,传统方法难于直接处理,建立了基于免疫系统抗体浓度调节原理的免疫遗传算法进行全局寻优.通过对部分上市建筑企业2002～2007年的绩效状况进行评价,表明基于投影寻踪模型的企业绩效评价与实际一致,可以对企业绩效进行动态评价,并且动态评价是非常必要的.     

基于知识管理视角的复杂产品研发绩效模型

复杂产品研发团队的知识管理显著地影响其研发绩效,基于知识管理视角研究了复杂产品研发团队的研发绩效。本文基于团队合作理论和知识管理理论,以复杂产品研发活动为背景,提出若干合理假设,应用经济学中成本-收益方法,建立了复杂产品研发绩效的数学模型,分析了影响复杂产品研发绩效的主要因素。研究结果表明:提高成员的知识接受能力可以提高研发绩效,但存在平台现象;团队规模与研发绩效之间呈现倒U型曲线关系;团队分组影响绩效,规模较大的团队适宜进行较多的分组;工作时间分配与绩效的关系取决于成员的知识接受能力。

On a class of self-similar processes with stationary increments in higher order Wiener chaoses

We study a class of self-similar processes with stationary increments belonging to higher order Wiener chaoses which are similar to Hermite processes. We obtain an almost sure wavelet-like expansion of these processes. This allows us to compute the pointwise and local Hölder regularity of sample paths and to analyse their behaviour at infinity. We also provide some results on the Hausdorff dimension of the range and graphs of multidimensional anisotropic self-similar processes with stationary increments defined by multiple Wiener–Itô integrals.     

A REPRESENTATION FORMULA RELATED TO SCHR(O)DINGER OPERATORS

Schr(o)dinger operator is a central subject in the mathematical study of quantum mechanics.Consider the Schrodinger operator H = -△ V on R, where △ = d2/dx2 and the potential function V is real valued. In Fourier analysis, it is well-known that a square integrable function admits an expansion with exponentials as eigenfunctions of -△. A natural conjecture is that an L2 function admits a similar expansion in terms of "eigenfunctions" of H, a perturbation of the Laplacian (see [7], Ch. Ⅺ and the notes), under certain condition on V.     

Qualitative Analysis of Bifurcating Solutions in the Lengyel-Epstein Model

One of the most fundamental problems in theoretical biology is to explain the mechanisms by which patterns and forms are created in the＇living world. In his seminal paper ＂The Chemical Basis of Morphogenesis＂, Turing showed that a system of coupled reaction-diffusion equations can be used to describe patterns and forms in biological systems. However, the first experimental evidence to the Turing patterns was observed by De Kepper and her associates（1990） on the CIMA reaction in an open unstirred reactor, almost 40 years after Turing＇s prediction. Lengyel and Epstein characterized this famous experiment using a system of reaction-diffusion equations. The Lengyel-Epstein model is in the form as follows     

On a class of Riemann surfaces

It is considered the class of Riemann surfaces with dimT1 = 0, where T1 is a subclass of exact harmonic forms which is one of the factors in the orthogonal decomposition of the spaceΩH of harmonic forms of the surface, namely The surfaces in the class OHD and the class of planar surfaces satisfy dimT1 = 0. A.Pfluger posed the question whether there might exist other surfaces outside those two classes. Here it is shown that in the case of finite genus g, we should look for a surface S with dimT1 = 0 among the surfaces of the form Sg\K , where Sg is a closed surface of genus g and K a compact set of positive harmonic measure with perfect components and very irregular boundary.     

(0,1 ;0)-INTERPOLATION ON INFINITE INTERVAL (-∞, +∞)

Staircase transportation problems with superadditive rewards and cumulative capacities

A cumulative-capacitated transportation problem is studied. The supply nodes and demand nodes are each chains. Shipments from a supply node to a demand node are possible only if the pair lies in a sublattice, or equivalently, in a staircase disjoint union of rectangles, of the product of the two chains. There are (lattice) superadditive upper bounds on the cumulative flows in all leading subrectangles of each rectangle. It is shown that there is a greatest cumulative flow formed by the natural generalization of the South-West Corner Rule that respects cumulative-flow capacities; it has maximum reward when the rewards are (lattice) superadditive; it is integer if the supplies, demands and capacities are integer; and it can be calculated myopically in linear time. The result is specialized to earlier work of Hoeffding (1940), Fréchet (1951), Lorentz (1953), Hoffman (1963) and Barnes and Hoffman (1985). Applications are given to extreme constrained bivariate distributions, optimal distribution with limited one-way product substitution and, generalizing results of Derman and Klein (1958), optimal sales with age-dependent rewards and capacities.To our friend, Philip Wolfe, with admiration and affection, on the occasion of his 65th birthday.Research was supported respectively by the IBM T.J.
