Performance measurement with classification information: an enhanced additive DEA model 总被引:1,自引:0,他引:1
This paper presents an improved measurement tool for evaluating performance of branches within a major Canadian bank. While there have been numerous previous studies of performance in the banking industry, particularly at the branch level, this study is different in a very significant way: specifically two kinds of data are used to develop the model. The first type of data is that related to standard transactions, available from any bank; such have formed the basis of numerous previous studies. The second type of data, obtained from the site studied, is classification information, based on branch consultant/expert judgment as to good and poor performance of branches. The purpose herein is to present a modified version of an existing benchmarking model, data envelopment analysis (DEA), and to show how this tool is applied in the banking industry. The mechanism used herein to incorporate expert knowledge within the DEA framework is to first apply a discriminant or classification tool, to quantify the functional relation that best captures the expert's mental model for performance. The outcome of this first phase is an orientation of variables to aid in the definition of inputs and outputs. The resulting orientation then defines the DEA model that makes up the second phase of the model. 相似文献

The objective of this study was to determine the impact of task information (TI) provided by an interface agent during the idea evaluation and integration step of the problem formulation stage of the problem solving process. The effectiveness assessment was based on solving diagnostic decision problems in the domain of complex industrial machinery. Ten domain experts participated in this study. Decision support was provided by a case-based reasoning system. Findings suggest that TI provided by the interface agent had no effect on the decision maker's performance, nor on the associated cognitive effort. However, a verbal protocol analysis revealed that the ten subjects used the interface agent to verify their decision processes. The results and their implications are discussed with respect to current findings in the area of decision support systems. 相似文献

Consider the problem of partitioning n nonnegative numbers into p parts, where part i can be assigned ni numbers with ni lying in a given range. The goal is to maximize a Schur convex function F whose ith argument is the sum of numbers assigned to part i.
The shape of a partition is the vector consisting of the sizes of its parts, further, a shape (without referring to a particular
partition) is a vector of nonnegative integers (n1,..., np) which sum to n. A partition is called size-consecutive if there is a ranking of the parts which is consistent with their sizes, and all
elements in a higher-ranked part exceed all elements in the lower-ranked part. We demonstrate that one can restrict attention
to size-consecutive partitions with shapes that are nonmajorized, we study these shapes, bound their numbers and develop algorithms
to enumerate them. Our study extends the analysis of a previous paper by Hwang and Rothblum which discussed the above problem
assuming the existence of a majorizing shape.

The Blinders of Dominant Logic 总被引:4,自引:0,他引:4
C.K. Prahalad Author Vitae 《Long Range Planning》2004,37(2):171-179
This article argues that the dominant logic embedded in an organisation may keep it on the road ahead, but it also acts as a blinder to peripheral vision. It says that managers need to look at beyond the borders of their industries and geographies to find new opportunities and rethink the logic of the business. It refers to corporate examples where shifts in organisations’ dominant logic allowed traditional assumptions about value creation to be reassessed and resulted in successful forays into the periphery. 相似文献

《郭店楚墓竹简》自从1998年问世后,一直引起中国内外学者的关注,成为研究先秦文字、历史、思想等领域的热门对象。然由于此批竹简的复杂性,再加上研究时间不长,因而尚有许多基本问题有待解决,而这些问题又是与竹简内容的正确理解息息相关的。如果郭店楚简几篇儒家逸书中的部分问题能够解决,便能够对其思想内涵及历史意义达到更进一步的认识。对《成之》篇作两处简序上的调整及对某些字提出新的读法后,便突显出了其中“恒”、“疾”、“终”的进阶概念,关于圣人对善道之“不拾”观念也可以有更深的理解。另外,对《唐虞之道》作简序调整,对《六德》中“多”字给新的解释,涉及问题虽小,但给先秦思想史研究带来的意义不可低估。 相似文献

理学作为一种思想体系受到朝廷的推崇,并作为科举考试的组成部分。在20世纪,对理学的看法发生了分歧。有人认为理学是智识与科学进步的障碍,中国要想走向现代化就必须摆脱理学。关于中国在12世纪后进入长时期停滞的看法,历史学界一般都不赞成了,但读者的这种看法还比较强烈。对于中国历史的一些基本特征的认识需要重新检验,比如中国文化不是只有一个起源;中国并非与外界隔离并拒绝外界影响;中国的政治体制不是绝对独裁;中国文化并没有一个纯正的“正统”或“道统”(orthodox);中国人并非没有自主的完整实体的“自我”观念。学者在实际研究中往往把中国当作一个实体民族或一个连续不断的文明体,这种观念并不太准确,实际是误解了China的原意。 相似文献
