Presents an approach for evaluating the number of vendors to employ in a procurement situation using multi‐objective programming (MOP) and data envelopment analysis (DEA). The approach advocates developing vendor‐order quantity solutions (referred to as supervendors) using MOP and then evaluating the efficiency of these supervendors on multiple criteria using DEA. Formulations are presented for both the MOP and DEA models. A case study is presented for a Fortune 500 company in a just‐in‐time (JIT) manufacturing environment.

Explores the use of a multi‐objective programming approach as a method for supplier selection in a just‐in‐time (JIT) setting. Based on a case study, develops a model of JIT supplier selection which allows for simultaneous trade‐offs of price, delivery and quality criteria. The analysis occurs in a decision support system environment. A multi‐objective programming decision support system is seen as advantageous because such an environment allows for judgement in decision making while simultaneously trading off key supplier selection criteria. An additional flexibility of this model is that it allows a varying number of suppliers into the solution, and provides suggested volume allocation by supplier.

Benchmarking has long been recognized as an important business activity. The primary goal of benchmarking is to produce a product or execute a process that is at least as good as the best firms producing similar products or performing similar processes. Important components of benchmarking include: determining what to benchmark, identifying the “best of the best”, collecting internal and external data and data associated with the “the best”, and analyzing how a firm can move from its current capability to that of the best. To date, benchmarking has been considered primarily as a producer/vendor based activity. This paper proposes that in many situations benchmarking should be viewed as a customer/purchaser based activity. The primary benefit of purchaser‐originated benchmarking is that it facilitates the collection of competitor's data and allows the customer to determine directly the product/process requirements desired.

While it has long been recognized that vendor selection is multi‐objective in nature, little has been done to develop techniques for measuring vendors’ performance on multiple criteria. Demonstrates the use of data envelopment analysis (DEA) as a tool for measuring the performance of vendors on multiple criteria and for use in vendor negotiations. Describes the DEA model, develops a DEA formulation for measuring vendor efficiency and, finally, shows how a baby food manufacturer applied the DEA technique in a just‐in‐time environment. Shows how application of the DEA technique can provide savings in monetary and other measurable terms.

This paper argues that the quest for meaning and the problem of suffering are in an irresolvable state of tension and that this tension remains of central importance in modernity and a prominent issue in the reconstruction of contemporary social theory and social science.
The approach focuses on an examination of the work of Max Weber and Emmanuel Levinas on issues of rationality and suffering bringing them into a productive dialogue and juxtaposition.
The work of Max Weber shows how practices of rationality in modernity are still haunted by the ethical call to responsibility that suffering incurs. The work of Emmanuel Levinas complements and reconfigures Weber’s framing of the issues involved and deepens the general point that a reconstructed social theory would incorporate the implications of suffering more deeply into its practices.
A social science and social theory oriented by an epistemological framework is inadequate to the ethical responsibility the presence of suffering invokes. A reconstructed social theory in an ethical framework calls for the best knowledge capable of being produced. As such, a nihilistic or disengaged pluralism, as well as a social science framed primarily by methodological concerns, is inadequate. What will be required is both critical examination of explicit and implicit assumptions of theory and research as well as active, engaged dialogical practices with alternative perspectives.
An engagement between Weber and Levinas is almost unprecedented, especially on issues rationality and suffering despite their shared perspectives. What Levinas offers the reconstruction of social theory today is explored.

Investigates the importance of English language sources of Friedrich Theodor Althoff (1839‐1908), a German of great influence both in his own country and, indirectly, in the United States. Explores some measures of his influence in education and international understanding. Examines a wide variety of sources. Explains how it could happen that an influential person would end up in intellectual history with almost no recognition. Challenges several conventional assessments. Althoff′s most important contributions are in print and more almost certainly exist in university archives, but the material is scattered and unorganized. Because we do not yet have the full story of this remarkable and complex man, firm conclusions about his influence are not yet possible.

The diversity of social forms both regionally and historically calls for a paradigmatic reassessment of concepts used to map human societies comparatively. By differentiating “social analytics” from “explanatory narratives,” we can distinguish concept and generic model development from causal analyses of actual empirical phenomena. In so doing, we show how five heuristic models of “modes of social practices” enable such paradigmatic formation in sociology. This reinforces Max Weber’s emphasis on the irreducible historicity of explanations in the social sciences.
A paradigmatic consolidation of generalizing concepts, modes of social practices, ideal-type concepts, and generic models presents a range of “theoretical tools” capable of facilitating empirical analysis as flexibly as possible, rather than cramping their range with overly narrow conceptual strictures.
To render social theory as flexible for practical field research as possible.
Develops a way of synthesizing diverse theoretical and methodological approaches in a highly pragmatic fashion.
