制造业项目结构分解过程模型研究

针对项目分解中工作分解结构方法的不足,以制造业项目为例,考虑项目产品本身的构造及特点的基础上,综合项目产品的工艺装配过程、产品数据管理技术以及项目组织结构,构建了项目结构分解的过程模型,并对该模型进行了详细分析,应用该模型能够更加科学、合理地进行项目分解,确定项目范围。

产品市场竞争、融资约束与公司现金持有:基于中国制造业上市公司的实证分析

本文采用我国制造业上市公司2001年-2007年共2401个公司年的平衡面板数据,利用行业间竞争、行业内竞争两个维度的产品市场竞争变量,实证分析了我国制造业上市公司产品市场竞争对现金持有水平的综合影响。实证结果显示,对于所有制造业上市公司来说,产品市场竞争对公司现金持有存在显著的掠夺风险效应。在考虑公司融资约束的情况下,产品市场竞争对公司现金持有的掠夺风险和代理成本两种竞争效应被有效区分开来。融资约束公司表现为显著的掠夺风险效应,非融资约束公司则表现为显著的代理成本效应。这些研究结论不仅丰富和补充了产品市场竞争与公司现金持有之间的相关研究,也为公司实施积极的现金流风险管理和持有现金的高效利用提供了实践支持。     

我国制造型企业市场导向和创新导向对新产品绩效影响的实证研究

本研究基于我国227家制造型企业的问卷调查数据,实证考察了市场导向和创新导向对新产品开发绩效的影响,以及创新导向和环境变动在市场导向和新产品绩效关系中的调节作用。结果显示:(1)本研究的概念模型整体拟合度优于西方常用模型;(2)市场导向和创新导向对制造型企业新产品开发绩效的影响显著为正,且均高于以前文献研究的一般水平;(3)创新导向和技术变化对于市场导向和新产品绩效的关系起到正向调节作用;(4)市场变化和竞争强度的调节作用不显著。研究结果对于制造型企业改善产品创新绩效具有重要的启示意义。     

多产品竞争中企业产品线最优区域的选择

多产品厂商产品线延伸收缩的决策,不仅仅与自身的竞争实力有关,还与产品的市场特性有关。低端市场上的产品处于生命周期末期,厂商的市场空间不断缩小,市场竞争异常激烈。而新兴市场上的产品从成长期向成熟期过渡,技术不断成熟,消费群体稳步增长。拥有技术优势的厂商必然会收缩低端产品线,放弃低端市场,然后延伸高端产品线,进入新兴市场,从而提升自身的利润水平;由于低端市场上厂商的退出,市场竞争烈度的下降,低端市场在位企业的利润水平也会因此有所改善。     

OEM product design in a price competition with remanufactured product

An original equipment manufacturer (OEM) produces new products and often faces a dilemma when determining the level of interchangeability in its product design. The interchangeability is considered as a degree to which the product can be disassembled without force, and thus an increasing degree of interchangeability would decrease the OEM's production cost, but it would also lower a remanufacturer's cost in cannibalizing used items. Decreasing the level of interchangeability to deter the remanufacturer, on the other hand, would simultaneously increase the production costs of the OEM. We thus formulate a two-period supply chain model consisting of two chain members, an OEM and a remanufacturer, to investigate the product design decision of the OEM and both chain members' competitive pricing strategies. We then characterize the equilibrium decisions and profits with regard to costs and consumers' preference for the remanufactured product. We also evaluate a strategic game in which the OEM chooses the degree of interchangeability, and the remanufacturer determines its collection strategy. We find that the product-design strategy is effective for the OEM in competing with the remanufacturer, but it is not necessarily harmful to the remanufacturer.     

Disentangling the effects of organizational controls on innovation

The strategy and innovation literatures argue that organizational competitiveness is contingent upon firms simultaneously pursuing both process and product innovations. A firm’s control system plays a fundamental role in this regard by managing, motivating, and coordinating employees’ behaviors for the development of its innovative capabilities. Research suggests that in order to develop successful innovation, management must use controls that align employees’ interests with those of the organization while simultaneously allowing employee autonomy to encourage creativity. These disparate functions lead to the control–autonomy dilemma. We argue that managers can address this dilemma by recognizing that the effect of controls on innovation outcomes depends, in part, on the controls’ enabling features and the type of commitment they inspire. Our findings show that employee development, which is the focus of input controls, has a direct effect on process innovation-related behaviors while specified goals, the emphasis of output controls, have a direct effect on product innovation-related behaviors. It is only through employees’ perceptions of managerial support that input controls increase product innovation-related behaviors and output controls increase process innovation-related behaviors.     

A Bayesian nonparametric estimator based on left censored data

Summary This paper introduces a Bayesian nonparametric estimator for an unknown distribution function based on left censored observations. Hjort (1990)/Lo (1993) introduced Bayesian nonparametric estimators derived from beta/beta-neutral processes which allow for right censoring. These processes are taken as priors from the class ofneutral to the right processes (Doksum, 1974). The Kaplan-Meier nonparametric product limit estimator can be obtained from these Bayesian nonparametric estimators in the limiting case of a vague prior. The present paper introduces what can be seen as the correspondingleft beta/beta-neutral process prior which allow for left censoring. The Bayesian nonparametyric estimator is obtained as in the corresponding product limit estimator based on left censored data.     

Approximate theory of multiway block designs

Optimality properties of multiway block designs are deduced from the general results of J. Kiefer's approximate-design theory. In the model with additive effects these optimality properties solely depend on the two-dimensional marginals of the designs. Uniform designs, and designs whose two-dimensional marginals are products of the one-dimensional marginals, are shown to be optimal. Approximate Youden designs are introduced for the case when the support sets of the two-dimensional marginals are prescribed in advance. They are optimal in a relatively small class of competing designs only.     

产品召回供应链中线性保险合约与订货决策

考虑一个由单供应商和单制造商组成的二级供应链,在不确定市场需求情形下考虑产品召回,站在制造商角度研究供应链线性保险合约下的最优订货决策以及最优线性保险合约决策。研究表明,最优的订货决策与产品召回概率以及线性保险系数相关,存在唯一的最优订货量来最大化制造商的利润。对于密度函数倒数的导数较大的一般需求分布函数,最优的线性保险系数与线性保险合约的固定费用以及产品召回概率有关。当产品召回概率和线性保险合约的固定费用均较小时或者产品召回概率较大但线性保险合约的固定费用适中时,制造商通过选择线性保险合约可以改善自己的利润。
