Key drivers of this decision, in turn, are the sizes of the discrete lots that comprise the flows. Thus, we formulate an original optimisation model that determines order lot-sizing decisions to minimise, for given constant arc flows, the sum of ordering cost and pipeline inventory cost on arcs and buffer inventory at DCs. The model employs an average throughput as a surrogate to estimate buffer inventory at facilities at which synchronisation is not economical and therefore serves to decouple inbound and outbound flows. Perfect lot-for-lot matching of shipments would impose very restrictive constraints on supply chain operations, but equality of average throughput indicates an innovative, relaxed mode of synchronisation. This mode is practicable for cross-docking by means of bulk-breaking or consolidation of shipments. A heuristic approach based on the Lagrangian relaxation and subgradient optimisation is developed for the non-linear mixed-general integer optimisation model, which is illustrated by numerical examples and tested using a benchmark data set.

This study measures the effects of employment experiences on university and classroom dynamics. Undergraduate business students from a large, private university constituted the sample. They were surveyed to determine the relationship between their university and work experiences. Findings suggest that work and educational efforts do not always compete. For many, it appears the same intangibles that propel individuals to excel in a job carries over into the academic arena. Implications for Business Education are presented.

However, the burst of the Internet bubble raised questions as to whether investments in such Internet-related services increase corporate profitability (e.g., Nagarajan et al., 2000). This article studies financial and operational values that web-enhanced services add to publicly traded interstate trucking companies. Large companies offering WES were found to be more profitable than smaller companies in general, and they were more profitable than other large carriers not offering WES. Investments in WES appear to provide a strategic advantage specifically for large companies.

These brand experiences affect consumer-brand relationship quality positively. Brand experience is composed of four dimensions: sensory, affective, behavioral, and intellectual. These are evoked by brand-related stimuli like brand design, communications and environments. In this research, we investigate which brand experiences affect brand relationship quality. Among four brand experience dimensions, we investigate affective and behavioral brand experiences, because affective and behavioral dimensions have a decisive effect on the brand attachment. According to this research, an affective brand experience affects brand trust and brand commitment positively. A behavioral brand experience does not affect brand trust meaningfully but positively affects brand commitment. Also we examine brand trust-brand commitment relationship and brand relationship quality-brand loyalty. Brand trust affects brand commi...

Patterson, Johnson, and Spreng (1997), Shapiro, Slywotzky and Doyle (1997), and Preis (2003) find increased customer satisfaction is one factor leading to such increased repurchase intentions. Thus, it is important to obtain a good understanding of the factors that affect satisfaction and hence influence repurchase intentions. While a great deal of research on customer satisfaction has been performed in consumer markets, the influence of customer satisfaction on supply chains has been largely ignored (Patterson, Johnson & Spreng, 1997; Szymanski & Henard, 2001; Homburg & Rudolph, 2000). Kellar and Preis (2003) show that the components of satisfaction that influence repurchase intention are d...

Components of overall satisfaction include satisfaction with the product (offering), satisfaction with the vendor's performance, and interpersonal satisfaction (satisfaction with the relationship with the salesperson). Research shows that industrial buyers evaluate components of satisfaction non-uniformly across various purchase categories (e.g., components of satisfaction are evaluated differently for capital equipment than for production process items). The same holds true for purchases of differentiated and non-differentiated (commodity) items; satisfaction with high-tech products is evaluated differently than for products with lower levels of technology. Data collected from a cross section of industrial offerings are categorized according to their levels of technology. Items from industries characterized by high expenditures on RD Szymanski & Henard, 2001; Homburg & Rudolph, 2001). ...

I do and I understand.--Confucius " The undergraduate business statistics (UBS) course provides students with an important business foundation. An understanding of basic statistical concepts can be critical to graduates' success (Lohr, 2009). While we, the authors, would like to think that we prepare our students to evaluate, analyze, and apply what they learn in UBS to real-world business problems, we reluctantly acknowledge that many of them fail to achieve these higher-order learning outcomes. One reason is that for many, statistics is a difficult quantitative subject in which one must learn numerous techniques. Frequently, the application of these techniques requires that students manually crunch numbers--often using only hand-held calculators. Students' anxiety over these expected computations often interferes with their ability to understand the relationship between statistical techniques and the object...

The effects of four components of satisfaction, satisfaction with the product, interpersonal satisfaction, satisfaction with price, and satisfaction with vendor performance, on overall satisfaction among industrial buyers are investigated. Results show that the component of satisfaction experiencing the largest level of negative (positive) disconfirmation serves as a lower (upper) bound on the level of overall satisfaction reported by the respondent.

This collaboration manifests itself when faculty are asked to work in partnership to create a curriculum that serves both students and industry. Unfortunately, the curriculum topics considered to be most important by academia are not necessarily the same as the topics that are important to industry. While academia's primary objective is to provide business students with a broad range of skills and experiences that will serve them throughout their entire careers, industry often seeks specific skills to meet its current requirements. Therefore, academicians should be interested in identifying those topics in which significant disagreement exists and in developing a resolution strategy. The authors compare data from (Evans, 1996) and (Weinstein et al., 1998) to that of follow-up surveys to examine these differences. They find that the preferences of both parties change over time. On some...

The analysis presents a profile of the journal including 1) article lengths and other descriptive characteristics, 2) the most prolific authors and institutional affiliations, 3) coauthorship patterns, 4) marketing topics researched, 5) citations and references, and 6) sizes of empirical data sets. Data compiled or available from retrospective analyses of other journals were used as standards of comparison against which to evaluate AMSJ. We conclude, based on the results of the analysis, that the journal is meeting its stated goals.

An individual faculty member's performance with respect to this requirement is frequently measured by the number of articles published (Haw...

Personal response devices (PRDs, sometimes called Audience Response Devices or ARDs, better known as clickers) show promise in helping to meet that need. This article explores the literature of PRDs to develop propositions about the impact of PRDs on learning in large introductory business classes (e.g., Principles of Marketing, Introduction to Supply Chain Management, Organizational Behavior, etc.). We report on two exploratory studies utilizing PRDs and discuss recommendations and observations on the use of PRDs.
