The impact of operations anticipations on the quality of stochastic location-allocation models

It is now a common practice to use optimization models, such as location-allocation models, to support the design of supply chain networks (SCN). The value creation potential of a SCN design must be evaluated in terms of capital expenditures, but also of the operating revenues and expenses incurred during the planning horizon considered. The design model used should therefore be formulated to anticipate these revenues and expenses (relatively) accurately over the planning horizon. In classical location-allocation models, the aggregate flow and throughput variables used yield very crude anticipations. It was never shown that they lead to the best SCN design that one should expect. This paper draws on the stochastic multi-period location-transportation problem (SMLTP) for studying the impact of various types of operations anticipations on the quality of the SCN designs obtained. Since accurate anticipations yield more complex models, solvability is also an issue. Several alternative SCN design models based on more detailed anticipations than the ones embedded in classical location-allocation models are proposed and tested. Accuracy-solvability trade-offs are explored and recommendations are made on the modeling strategy to use to get better SCN designs.     

The impact of participation on management in Germany

The German experience with the two-tier board system is outlined. In industry, where the supervisory board consists of one third elected worker-directors, the system appears to work satisfactorily, but it is less successful in the mining and steel industry, where they constitute half the board.     

The impact of national culture on negotiating behaviors across borders

Recent declines in American competitiveness and the increasing globalization of American business underscore the importance of one's culturally-based negotiating ability in international business transactions. This paper examines the impact of cultural dimensions on negotiating effectiveness on three levels: the role of a single dimension of culture, the interactive effects between multiple dimensions of culture, and the degree of cultural compatibility between negotiating parties. Two existing models of negotiation are integrated, outlining the critical importance of culture in each stage of effective international business negotiations. The integrated model is then applied to the cultures of eleven nations. Propositions and suggestions for future research are provided.An earlier version of this paper was presented at the Academy of International Business Conference. The authors wish to thank two anonymous AIB reviewers and session participants at the AIB meeting for their constructive comments concerning the paper.     

The impact of language and culture on perceived website usability

Online retailers offering their products across national and cultural borders are eager to enhance the usability of their websites to attract large numbers of visitors. The results of the present research show that the perceived usability increases when the website was originally conceived in the native language of the user. Thus, translation, even though of excellent quality, creates a cultural distance which impacts on the web users’ evaluation of the site. Conversely, where language is less important, such as in the evaluation of the quality of an offer, a consumer's native language has no impact on the buying decision.     

The importance of operations management problems in service organizations

This article reports on the research to empirically determine which operations management problems are the most important to small service organizations. The authors asked managers of service organizations to rank a set of operations problems according to their relative importance using Q methodology. In this article, Q method is explained, significant factors are analyzed, and explanations are offered for the ranking of the operations problems. The results indicate that forecasting, quality management, and resource utilization are important operational issues for service organizations. However, the results also indicate that facility location and layout, waiting line systems, and distribution requirements planning were for the most part unimportant to the respondent service organizations. In addition, Schmenner's service typology does not provide an explanatory basis for the variations in the factor results. Lastly, the results are used to suggest operations management techniques that should be taught to students who are expected to work in service organizations upon graduation.     

A queuing/management consideration on Japanese production systems

A single-stage lot/cell production under a Poisson arrival and exponential service in a batch is considered. The three economic queuing models of push and pull types are presented, an economic comparison of push versus pull types is considered, and a strategic management/design consideration to the lot production is given. First, the total expected operating cost is given for the three queuing models including the Omote-Kanban type similar to VMI. Second, the push versus pull system is discussed from a view of setup time, inventory or operating cost, and it is ascertained that the three types are alternative. Finally, a strategic management basis for economic traffic, leadtime setting is given, and discussed by the introduction of production matrix on 2-stage design.

Editorial for special issue on: humanitarian operations management

Abstract

Over the past decades, there has been increasing interest in studying humanitarian operations management. The mismatch between global humanitarian needs and the resources available, together with chronic vulnerability in many parts of the world, continues to have a direct bearing on the lives of millions of people in need of assistance. It also means that donors have to re-double their efforts to respond to disasters in a more efficient and effective manner. International humanitarian organizations (IHOs) often deal with a mix of disaster response and development programmes simultaneously. This operational mix entails disaster cycle management challenges such as project and programme planning of multi-objective global logistics, balancing earmarked donations for disaster response with budget needs for development programmes, and determining the push-pull boundaries in the supply chain, particularly with the increase in cash transfer programmes. The main purpose of this special issue is to report on research in humanitarian operations management. This special issue attempts to explore and examine the above topical issues at strategic, operational and technical levels.     

The privatization of British Telecom—Its impact on management

This article describes the series of changes which British Telecom has gone through over the last 10 years or so— changes which have often been dramatic and highly publicized. Faced with the challenges of the fast-changing business environment of the past decade—the most obvious of which was the technological revolution—British Telecom was perceived to be safe and reliable, but slow to change and expensive. Its strengths were the widespread understanding and acceptance of the need for change, its reservoir of the necessary skills and talent, a sound commercial infrastructure and a corporate culture. The author describes the organizational changes which have taken place and looks to a future where change is endemic if a business is to survive.

Squeezing or cuddling? The impact of economic crises on management control and stakeholder management

This paper analyzes the effects of economic crises on firms’ use of management control mechanisms and on their management of stakeholder relations. Moreover, the association between stakeholder management and management control system use is analyzed. In the wake of the economic crisis of 2008/2009, many firms were faced with severe threats that called for immediate short-term action to ensure firm survival. However, short-term action like massive cost-cutting and cash generation often are blamed for going at the expense of long-term health as key stakeholder relations may be irreversibly harmed. Hence, three interrelated questions are addressed theoretically and empirically: First, we analyze the impact of the recent economic crisis on firms’ control strategies. More specifically, we investigate whether a high crisis impact on firms is associated with a shortening of reporting cycles, a more interactive use of control-relevant information, restriction of employee autonomy and a focus on liquidity and cost-cutting. Second, we examine from the viewpoint of stakeholder theory how firms can make use of active stakeholder management for crisis management. Third, we explore whether firms can take short-term measures for ensuring liquidity and cutting costs and at the same time pursue a stakeholder strategy aiming at the long-term survival of the firm. Using survey data from 204 major Austrian corporations, we provide evidence that firms significantly adjusted their control systems as a response to the economic crisis. Our data do not indicate an immanent contradiction between a “short-term finance focus” and the pursuit of a sustainable stakeholder strategy.     

The impact of culture on interactions: five lessons learned from the European Commission

Using data collected from 25 interviews with Austrian employees in the European Commission, we explore the conditions under which cultural differences do and do not influence interactions. Previous experience with culturally-determined behaviour and experience working in a foreign language is found to foster norms that reduce conflict based on cross-cultural differences. Time pressure, on the other hand, makes cultural differences, specifically the way that criticism is delivered and the extent of relational-versus-task orientation, more explicit. Our findings have implications for the design of training for multinational teams, as well as the composition of these teams.     

The impact of knowledge management and strategy configuration coherence on SME performance

According to recent literature, effective knowledge management should be coherent and based on the firm’s strategy. Prior empirical research, in contrast, tries to evaluate the impact of knowledge management initiatives directly on performance but finds inconsistent results and not allows the understanding of knowledge management contribution to competitive advantage generation. In this study we aim to investigate the impact of knowledge management and strategy configuration coherence on SMEs innovation and organizational performance through a quantitative analysis carried out on a sample of 60 manufacturing SMEs in northeast Italy. Our findings reveal that a significant coherence exists between knowledge management and strategy configurations. Most of the SMEs with a prospector and defender strategy adopt, in turn, an aggressive and conservative knowledge management. Moreover, we find that such coherence has a significant impact on the overall performance. This is particularly interesting since it suggests that the inconsistency in the results of prior studies on the impact of knowledge management on performance (Kalling in J Knowl Manag 7(3):67–81; 2003) may be due to the lack of consideration of knowledge management and strategy configuration coherence.     

The impact of supply chain management practices on competitive advantage and organizational performance

Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance since competition is no longer between organizations, but among supply chains. This research conceptualizes and develops five dimensions of SCM practice (strategic supplier partnership, customer relationship, level of information sharing, quality of information sharing, and postponement) and tests the relationships between SCM practices, competitive advantage, and organizational performance. Data for the study were collected from 196 organizations and the relationships proposed in the framework were tested using structural equation modeling. The results indicate that higher levels of SCM practice can lead to enhanced competitive advantage and improved organizational performance. Also, competitive advantage can have a direct, positive impact on organizational performance.     

The impact of JIT on capacity management: A case study and analysis

This article describes the production planning and control techniques used at Verbatim Computer Disk Company in Charlotte, NC. The factory operates by management policy on a 24 hours-per-day, 7 days-per-week, 363 days-peryear, basis as if it were a process industry. Production of discrete units, computer disks, follows repetitive manufacturing methods including the implementation of just-in-time JIT methods into an existing material requirements planning MRP system. Production is based on the actual customer orders received from Marketing for disks from both US customers and international markets. Marketing uses price adjustments in coordination with Production Planning to ensure the factories operate at 100 capacity and within predefined inventory levels. This article discusses the relationship between Marketing and Manufacturing which allows for the attainment of a process industry-like economies of scale for a line of discrete products. Key characteristics of the production planning and control system are identified as are the current operating problems.     

Behavior-based analysis of knowledge dissemination channels in operations management

One essential requirement for the development and vitality of a discipline is a network of channels for knowledge dissemination. These channels, such as scholarly journals, furnish not only a means for knowledge sharing, but also for knowledge generation by the discipline's community of researchers. In the field of operations management (OM), there have been several studies that have sought to rank journals relevant to OM research, using opinion surveys, citation analyses, and author affiliations. However, each of these methods has some limitations. This paper adopts a new approach for discerning journal publication patterns in the OM field. It is based on an examination of the actual publishing behaviors of all full-time, tenured OM researchers at a sizable set of leading research universities in the US. This behavior-based methodology provides three metrics that individually, and in tandem, give a basis for rating publication outlets for OM research in terms of their relative importance. The ratings can be used by scholars and administrators to assist in monitoring, disseminating, and evaluating OM research outlets.
