MODELING UNCERTAIN FORECAST ACCURACY IN SUPPLY CHAINS WITH POSTPONEMENT

We examine a situation where a manufacturer operates in a two‐mode production environment. The first mode could involve overseas vendors and manufacturing facilities. If additional units are later required, the company must use its second mode—more expensive last‐minute domestic vendors and manufacturing sites. We develop a new methodology for analyzing the impact of forecast accuracy on the decision to postpone production. We examine the interaction of forecast accuracy, shortage vs. holding costs, transportation costs and the cost of postponing production in the supply chain of a single product facing uncertain demand. Our model can be used to analyze the cost of important changes, such as increasing forecast accuracy, reducing the cost of backorders, lowering the cost of delaying production, or lowering transportation costs. Our model allows a firm to understand its overall cost structure so that it can accurately evaluate the impact of improved forecast accuracy and lowered costs in the context of postponement.     

When Philosophy and Business Professors Talk: Assessment of Ethical Reasoning in a Cross Disciplinary Business Ethics Course

Can instructors with apparently divergent approaches to the goals and methods of teaching business ethics agree upon a core set of course objectives? Can they agree upon a common method of assessment for measuring student performance against shared standards? This paper reports the results of a project intended to address these questions. The goals of the project were threefold: (1) to identify a shared set of core competencies for all students in business ethics; (2) to adopt a common assessment of ethical reasoning (neutral to disciplinary bias) for measuring student performance in core competencies; (3) to determine whether students show improvement in core competencies over the course of a semester. Our findings suggest that it is possible to find common ground in measurable objectives and to expect instructors to interpret, apply, and teach to these objectives effectively without infringing upon their disciplinary differences.     

Transdisciplinarity in urban South Africa

The ideals and assumptions associated with a transdisciplinary approach to environmental issues are investigated through the experience of a three-year research project in KwaZulu-Natal, South Africa focused on low-cost housing. Through this work, transdisciplinarity was conceptualised not as a panacea to create an all-encompassing research approach, but as an attempt to move away from paradigm isolation and allow researchers to integrate and develop a synthesis from their separate contributions. The paper discusses aspects of transdisciplinarity including definitions, methodologies, team-building, paradigmatic rigidities, the negotiation of power in the production of knowledge with stakeholders and community partners, and institutional challenges. Trade-offs include loss of data resolution at times, but are offset by deeper understanding of the complexities and constraints of applied environmental and social research in contemporary South Africa.     

Economics of Engineering: A New Fabric from Some Old Threads

Three axioms are used to present the basic fundamental ideas of engineering economics. These axioms are then used to derive a generalization of present value that includes both a local and global perspective. The relationship between the local and global concepts is derived and then used to solve cash flow problems that involve flows placed arbitrarily in time.     

THE IMPORTANCE OF INDUSTRY STRUCTURE FOR THE DETERMINATION OF FIRM PROFITABILITY: A NEO-AUSTRIAN PERSPECTIVE

This paper is concerned with exploring the degree to which industry structure determines firm performance. Most of the business policy literature follows Porter in arguing that industry structure has an important influence on firm level profit rates. the arguments contained in this paper take a counter position. It is argued that a plausible alternative to the hypothesis that industry structure matters is the hypothesis that (holding demand constant) individual firm differences are the most important determinant of firm profitability.     

DIVISIONALIZATION,DECENTRALIZATION AND PERFORMANCE OF LARGE UNITED KINGDOM COMPANIES 1

Questionnaire survey data from 144 large U.K. firms are used to describe and discuss the nature of organization design in major companies. It was found that the majority of firms were multidivisional. However a considerable variation in internal operating procedures was found which emphasized that many multidivisional companies do not behave in the way that the strategy/structure literature predicts. Empirical testing of the relation between structure and financial performance also emphasizes that divisionalization is not necessarily the key to a superior profit performance. Rather it would appear that organizational procedures need to be reconsidered in the light of recent divisional structures established in many companies. It is argued that a powerful divisional head office may weaken overall performance and that instead greater attention should be paid to the opportunity to decentralize operating decisions to the individual business units within each division.
