Lattice path combinatorics for multiple product identities

Lattice paths are enumerated as walks on a lattice under the Delannoy criterion of vertical, horizontal and upward diagonal steps. Delannoy recursions are generalized for arbitrary weights in each of these directions, where the row elements of the Delannoy triangles correspond to lattice paths for all walks at a given length.     

Determining the effects of intraclass correlation on factorial experiments

This paper considers the effects of the presence of eqmi-correlation between observations in a k-way factorial experiment, A technique to provide unbiased F-tests is also constructed.     

Linking aggregate production planning with marketing pricing decisions

In this paper, we link production planning decisions to marketing decisions that involve the price of product groups. The focus of this paper is the development of a closed-loop procedure for aggregate production planning and pricing. We seek to satisfy uncertain demand while minimizing total costs that include material, labour, and inventory holding costs. The procedure is useful for variable demand to update short-term aggregate plans.     

试论我国产品责任制度立法之完善

从八十年代以来,我国先后颁布了一些有关产品责任制度方面的法律法规,对调整产品责任关系,有效保护广大消费者合法权益,保障社会经济秩序正常运行,起到了十分重要的作用.但是随着时间的推移和社会经济的变化,其不完善之处已日益明显,进一步完善我国产品责任制度势在必行.     

接受美学与品牌塑造

西方接受美学理论的内涵是“读者决定一切”,外国品牌的塑造真谛是“以消费者为中心”,两者的理论观点异曲同工,他们都启迪、受益于马克思主义、毛泽东思想。21世纪的中国企业应以中国人自己的先进思想,探索中国品牌原理,让中国的品牌健康生长、迅速发展。     

组织冗余的利用对中国企业创新产出的影响

从冗余的控制权的角度将企业已吸收的冗余划分为分散冗余和组合冗余,分析了这两种冗余的利用对企业创新的影响,构建了一个包含冗余、吸收能力与创新之间关系的结构方程模型,并运用在607家企业进行的问卷调查所获取的数据实证检验了这个模型。结果显示,分散冗余和组合冗余分别与产品创新和过程创新存在显著的正相关关系,不同的冗余与不同的吸收能力之间存在一定的匹配关系,这种关系能够导致不同的创新产出。结果表明,中国企业的冗余与西方企业的冗余一样,都能够促进企业的创新产出,因此,广泛采用一刀切式的“减员”手段未必是中国企业“增效”的最有效率的策略。     

成套产品定价方法研究

在给出成套产品定价的概念的基础上,通过一个简单的算例来说明成套产品定价方法的思想,给出了纯成套产品定价方法的总收益大于产品单卖时的总收益的条件,并给出了混合成套产品定价时最优成套出售的套数k^#存在的区间。     

Estimation of Distribution Functions Using Data from Different Environments

Suppose that when a unit operatesin a certain environment, its lifetime has distribution G,and when the unit operates in another environment, its lifetimehas a different distribution, say F. Moreover, supposethe unit is operated for a certain period of time in the firstenvironment and is then transferred to the second environment.Thus we observe a censored lifetime in the first environmentand a failure time of a ``used' unit in the second environment.We propose an EM algorithm approach for obtaining a self-consistentestimator of F. Moreover, suppose using observations from both environments.The case where failure times are subject to right censoring isconsidered as well. We also establish the maximum likelihoodestimator of F. Moreover, suppose when the unit is repairable. Applicationand simulation studies are presented to illustrate the methodsderived.     

Supplier involvement in product development in the electronics industry: A case study

The movement of activities earlier in the product development process requires a re-examination of the total supply network. The objective of this paper is to determine the degree of early supplier involvement (ESI) that exists between a multinational electronics company and its key suppliers, in terms of depth of integration, information exchange and buyer–supplier relationships. The paper provides insights into the strategic factors that affect the dynamics of the ESI process. The research indicates that there are considerable impediments for those participants responsible for establishing and managing the implementation of ESI. A number of strategic insights are identified that explain the existence of the impediments to the ESI process. Finally, based upon the findings a number of lessons are highlighted for organisations considering the adoption of the ESI process.     

旅游产品特点的新视角——论旅游产品的本质特征

已形成的旅游产品特点理论尚停留在对旅游产品的表层概括抽象上 ,未揭示出旅游产品特点的深层本源 ,从而未能说明旅游新产品与一般服务性产品的差异。抓住旅游吸引物 ,揭示旅游产品的本质特征 ,才能说明旅游产品既不同于一般实物产品又异于一般服务产品的特点 ,从而为旅游学成为真正独立的学科和旅游业成为独立的产业奠定可靠的理论基础
