基于公司不进行正式研发投资的简要探讨

本文我们研究了正式的研发投资的频率。用实物期权和基于知识的观点去解释一个公司的知识资源是怎么影响该公司用于确定技术选择的研发投资频率。详细的说,我们得出一个公司若没有内部知识资源,很可能就总不投资研发;若有内外部知识资源,公司有时投资研发;但有内部知识资源而没有外部知识资源时,公司很可能总是投资研发。     

带容量限制的双配送中心选址方法

研究了带容量限制的双配送中心选址问题,结合聚类算法、重心法构造了一个解决双配送中心选址问题的算法。首先根据聚类算法思想将整个配送服务区域划分为两部分,再运用重心法进行配送中心初始选址,然后根据就近原则选择离重心点最近的备选地点作为配送中心初始选址。考虑到配送中心的容量限制,当某一个配送区域中各需求点的总需量超过配送中心的最大容量时,就对该区域的部分需求点进行调整,即从该区域调入另一区域。调整后,再次运用重心法进行配送中心初始选址,然后根据就近原则选择离重心点最近的备选地点作为配送中心最终选址方案。     

通识知识学习对学生就业能力培养的意义分析

日益激烈的人才竞争对学生的就业能力提出了新的、更高层次的要求,通识知识的学习是培养学生的人文素质和综合职业素质的重要途径和方法,本文通过对通识知识学习的深入分析,探讨了通识学习对于提高学生就业能力的影响和意义。     

基于两层架构协调的应急物资分配与车辆调度集成优化方法

针对突发事件下的应急物资调运问题,考虑了多个地区同时受灾以及多个出救点需要对其进行救灾并且各出救点的运力有限的情况,以最小化总的车辆运输费用,最大化救灾效率、各受灾点的救灾满意度,以及各受灾点得到救助的公平性为目标,建立了该问题的多目标混合整数非线性规划模型,并提出了一个基于两层架构协调的迭代式遗传算法进行求解。基于仿真数据的实验结果证明了所提出的模型和算法的有效性。     

突发事件下决定供应链敏捷力的关键要素研究

突发事件引起供应链中断或失效而造成商品断供或滞销的情况,对供应链敏捷力提出了新的要求。本文在全面梳理供应链敏捷力理论内涵的基础上,对新冠肺炎疫情期间283家复工复产企业进行调查,实证分析了决定供应链敏捷力的关键要素及其对供应链敏捷力的直接作用以及各要素之间的二阶交互调节作用。研究发现:市场响应对供应链敏捷力的正向促进作用不明显,但有显著的正向调节作用;物流服务则对供应链敏捷力正向促进作用明显,而正向调节作用几乎不存在;协调一致、供应能力、制造能力对供应链敏捷力均起正向作用,其中协调一致最为显著。在突发事件下,协调一致在某种形式上表现为“集中管理”模式,它有助于提高供需匹配的时效性。     

考虑物料、产能和客户优先级三重约束的订单允诺管理问题研究

客户订单允诺管理是在市场全球化的背景下．综合考虑各种资源有限性,对客户的订单给予准确的答复．因而具有很好的应用前号。文章对现有客户订单允诺模型做出改进,在供应链资源即物料和产能双重限制下,加入客户优先级约束,通过建立模型求解,给出合理的客户订单允诺机制。文中不仅定性分析客户优先级．而且将客户优先级量化为客户价值来表示,使该订单允诺管理机制更为有效．更有利于企业的长期可持续发展。     

Managerial markets in transition in Central and Eastern Europe: a field study and implications

In this paper, we report findings from the first comprehensive study of managerial labour markets in Central and Eastern Europe, drawing on field data from 157 firms in six countries. Results indicated widespread and deep changes occurring in the region’s managerial markets. Despite differences among countries in reform and economic performance, we found these particular changes to be surprisingly common across the countries studied. They included rapid rises in salary and benefit levels, narrowing of some skill gaps, shifts to more sophisticated methods of recruitment and an overall move towards Western management practices. The study also revealed severe shortages of qualified managers in all the countries studied. The resulting tightness in the managerial labour markets was reducing only modestly, despite other improvements. Foreign and joint-venture firms were relying disproportionately on expatriate managers, and may not have been sufficiently developing locals. We argue that, partly because of this, the distortions in pay, promotions and performance resulting from these tight markets are likely to persist for some time.     

Performance Management in Universities: Effects of the Transition to More Quantitative Measurement Systems

The measurement of research and teaching performance is increasingly common within universities, driven probably by the rise of New Public Management (NPM). Although changing over time and varying from country to country, NPM involves the use of private sector methods in the public sector. Traditionally, performance measurement in universities has had a developmental role – helping individuals to improve their (future) performance. However, the new systems seem more judgemental – i.e. seeking to quantitatively evaluate (past) performance. We study performance measurement in two Accounting and Finance groups – one in the Netherlands and one in the UK. In both we see an increasing use of judgemental forms of performance evaluation and, in particular, the use of more quantitative performance measures. The use of these more judgemental quantitative systems is seen to have various effects. Although these systems emphasise objective quantitative measures, they relocate subjectivities (usually at a greater distance from the subject), rather than remove them. This creates uncertainty and anxiety about how the systems are used. There is a danger that the new systems could inhibit creativity in teaching and limit contributions to the world outside the university. Furthermore, they could damage creativity and innovation in accounting research – as researchers play safe in getting the publications they need. As we are both researchers and practitioners in this area, we should be challenging these trends and pointing to the dangers for research (and teaching) in our field.
