顾客在新产品开发中的角色扮演研究

顾客在新产品开发(NPD)中具有越来越重要的作用,他们不仅仅是产品和服务的被动接受者,而且渐渐成为企业知识的主要来源。顾客在NPD中的作用可以用三个不同角色来描述:资源、使用者和共同创造者,并分析了在NPD过程中这三个角色所能发挥的作用。     

学术期刊开放存取的内在逻辑与发展趋势

学术期刊开放存取已经成为目前中国学术期刊界研究的热点问题，学术期刊的属性是分析学术期刊开放存取内在逻辑的前提和基础。从学术期刊的准公共产品属性出发，分析学术期刊开放存取的内在逻辑性，进而通过将开放存取与中国目前发展已相对完善的学术期刊商业数据库传播模式的对比，分析其在中国的发展趋势。分析认为，开放存取模式将不会取代商业数据库传播模式而成为中国学术期刊网络传播模式的主流。     

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。     

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.
