企业目标体系及其对跨世纪企业管理的影响

在分析企业发展历程和规律的基础上,揭示了现代企业系统的目标体系：战略层次的终极目标是使企业长期保持兴盛状态,策略层次的管理目标经历了从利润最大化到“满意的利润”,再到谋求股东和职工双方利益的最大化;战术层次的运作目标是不断提高经济效益。建立科学的企业目标体系是制约因素管理最重要的理论基础之一,制约因素管理强制围绕系统目标的实现。抓住制约环节进行全局调控,不断实现整体持续优化,它为跨世纪的企业管理展

基于复杂性科学的企业专利能力影响因素分析

企业专利能力是一个复杂性系统,具有动态性、层次性、整体性和开放性特征。企业专利能力的复杂性主要由两个部分决定,一是来自企业内部的因素,另一部分是由外部环境所决定的。人的复杂性和企业的复杂性是影响企业专利能力的内部因素,其中尤以创新因素为主。经济发展、专利制度和专利政策以及知识产权文化是助推企业专利能力培育的重要外部因素,其中尤以专利制度和专利政策为主。     

A DYNAMIC OPTIMAL ADVERTISING MODEL FOR NEW PRODUCTS

Many dynamic optimal control models for advertising make efforts to solve the problem of determining optimal advertising expenditures and other variables of interest over time for a firm or several competing firms,However,after analyzing the extant literature,one can find that few dynamic optimal advertising models available consider the problem within the product diffusion framework.Furthermore,the established models involving product diffusion are inspired by the Bass model,which has been out of date.This paper poses a dynamic optimal advertising model for new products,which considers the product diffusion based on the relative newly developed generalized version of the Bass model.In this paper,the optimal control model is used to derive the optimal advertising expenditure policy,which gives some implications to advertising practice.     

A REVIEW OF ENTERPRISE SUPPLY CHAIN RISK MANAGEMENT

This paper reviews enterprise risk management practices in the context of supply chains. Starting with the importance of managing supply chain risks, the paper established the benefits of managing risks using an enterprise-wise integrated approach.

A PURCHASING DECISION： SELECTING A SUPPLIER FOR A CONSTRUCTION COMPANY

1. Introduction Since the purchasing function has become vital in determining the profitability and survival of business organizations, it has been receiving considerable attention. As Sarkis and Talluri (2002) indicated, buyer-supplier relationships based solely on price are no longer acceptable. The increasing importance of supplier selection decisions is forcing organizations to rethink their purchasing and evaluation strategies because a successful purchasing decision directly depends on …

咨询团队参与下情绪对精益数字化推行的影响

针对精益数字化推行中第三方咨询团队和企业员工情绪变动影响策略选择,进而影响推行效果的问题,引入等级依赖期望效用模型,讨论了参与主体情绪和策略选择之间的演化机理.研究表明,情绪影响下演化均衡策略具有不稳定性,悲观情绪对策略选择的影响程度高于乐观情绪;若一方选择“合作性”策略,另一方情绪乐观且非过于乐观时,策略演化结果为完全合作.若一方选择“对抗性”策略或情绪悲观,策略演化结果为完全对抗或对抗合作;若主体情绪悲观或极度乐观,则情绪越强烈选择“对抗性”策略的可能性越大.若主体情绪适度乐观,随着乐观程度的加大选择“合作性”策略的概率也会随之增大.     

A NECESSARY AND SUFFICIENT CONDITION FOR A POINT TO BE A GLOBAL MAXIMIZER OF A CONSTRAINED OPTIMIZATION

It is difficult to judge whether a given point is a global maximizer of an unconstrained optimization problem. This paper deals with this problem by considering global information via integral and gives a necessary and sufficient condition judging whether a given point is a global maximizer of an unconstrained optimization problem. An algorithm is offered under such a condition and finally two test problems are verified via the offered algorithm.     

中国证券多因素及三因素定价模型实证研究

提出股票定价的包括宏观经济变量、微观经济变量、市场变量的多因素以及内在价值、技术因素、流动性的三因素资产定价模型,并对中国股市进行实证,发现市场指数回报率对股票的收益率的影响具有决定性的影响,市场指数回报率β系数显著为正,而且其系数变化的区间为0.41至0.53之间,说明市场指数对股票的收益率的解释力达到41%至53%之间,平均为50%.每股盈余增长对股价的影响为最大,每股盈余增长系数估计值显著为正,接近于1,表明每股盈余增长对股票收益呈现出正的影响,即每股盈余增长一个百分点,年预期收益平均增加一个百分点.而GDP增长、货币供应量增长、存款利率增长、通货膨胀率、存款增长、贷款增长等,其系数估计值显著为负,表明股票收益率为我国宏观经济变量的减函数.实证结果显示:多因素模型能有效地找出股票定价的关键因素,而三因素模型能够对资产价格主要因素进行定价.

COURSE TIMETABLING AT A TUNISIAN UNIVERSITY： A CASE STUDY

This paper deals with the Course Timetabling Problem at an institution in a Tunisian University. We introduce a heuristic procedure to construct a feasible timetable for all lectures and tutorials taken by different groups of each sub-section of any section. We describe the timetabling problem using a list of all specific hard and soft constraints. We formulate the problem as a set of linear constraints using two sets of binary variables corresponding to lectures and tutorials, respectively. This heuristic is illustrated with real data for a sub-section of the Faculty of Economics and Management Sciences of Sfax in Tunisia, and the resulting timetables are compared with those generated manually. The results of another full section have confirmed the good quality of the proposed heuristic when compared with the hand made solution.     

ORGANIZATIONAL LEARNING AND VENDOR SUPPORT QUALITY BY THE USAGE OF APPLICATION SOFTWARE PACKAGES： A STUDY OF ASIAN ENTREPRENEURS

In this paper we study how organizational learning impacts organizational behavior, and howvendor support quality enhances product adoption and usage behavior.These constructs were verifiedusing Application Software Packages(ASP)-a prewritten, precoded, commercially available set ofprograms that eliminates the need for individuals or organizations to write their own softwareprograms for certain functions. The relationship between ASP usage, usage outcomes and useprocesses were also investigated. Two hundred and ninety-five Chinese, Indian, and Malayentrepreneurships were studied. It was found that usage outcome strongly determines usage, while useprocess has only an indirect relationship (via outcome) on usage. The impact of organizational learningand vendor service quality on usage, usage outcome, and use process were robust. Theoretical andpractical implications of the research are discussed.

基于因素空间的煤矿安全情况区分方法的研究

为了将汪培庄先生提出的因素空间与因素库理论应用到实际研究,本文就该理论的特点,应用其概念分析和推理能力,考虑到目前煤矿安全分析大多采用定性论述的现状,对煤矿的安全情况论述使用概念分析表进行了推理和化简,以降低安全性论述中冗余信息对定性安全评价的影响,得到简洁准确的安全性概念,从而对不同煤矿企业的安全情况进行区分.结果表明:在研究对象集合U和因素集合F不变的情况下,按照不同的因素排序进行划分得到的概念格是不一样的;初始的安全性描述可以通过合理安排因素排序和去掉虚分得到较为简化的概念格,而得到相应简化的安全性描述;使用因素空间与因素库的概念,对安全性概念进行推理并化简是可行的,可用于区分多个煤矿的安全情况的差别,并进行分级和对比.     

我国有色金属进出口贸易的影响因素分解及其变化趋势

运用对数平均迪氏指数(logarithmic mean weight division index, LMDI)分解方法, 首次建立了我国有色金属产品进出口贸易的指数分解模型, 从多个角度系统地分析了2004年1月-2009年1月, 我国有色金属产品特别是铜和铝产品进出口贸易及其三种主要影响因素(总量因素、结构因素及价格因素)的贡献程度和变化趋势. 研究表明: 有色金属进口额的主要影响因素在2006年前后发生显著变化. 2006年之后, 随着有色金属价格的不断攀升, 价格因素成为了影响中国有色金属进口额波动的主要因素. 同时有色金属出口额的主要影响因素在2006年前后并未出现明显变化. 在国际有色金属价格大幅攀升时, 我国有色金属出口额并未同步增长.     

A ROBUST DECOMPOSITION OF LINEAR PROGRAMMING USING A GOAL-PARTITIONING METHOD

The Dantzig/Wolfe linear programming decomposition algorithm has had important economicinterpretations as well as a widespread impact on solving large scale linear programming problem.Inthis paper we consider a similar underlying structure,where however there is only one couplinginequality or equation.With this simplification,we demonstrate how to achieve an equitable partitionof the overall coupling resource to individual subproblem constraints through a simple iterationprocedure which appears to be very efficient.

OBSERVING THE HEAT EQUATION ON A TORUS ALONG A DENSE GEODESIC

Several authors have considered observability problems for the heat equation and relatedpartial differential equations.A basic problem is to determine what kinds of sampling providesufficient information to uniquely determine the initial heat distribntion.We address the case wherethe temperature is measured while travelling along a curve.We consider the special case where the space is a flat torus(of arbitrary dimension)and thecurve is a geodesic.It is shown that,in this case,the observed temperature is sufficient informationto uniquely determine the initial heat distribution if and only if the geodesic is dense in the torus.In the case of a torus,Fourier analysis techniques can be used to write down the solution of theheat equation.This allows us to derive an explicit representation of the observed temperature interms of the initial distribution.We use this representation and some ideas from the theory ofalmost periodic functions to show that the Fourier coefficients of the initial distribution can berecovered from the observation.
