Sales And Operations Planning: A Performance Framework, Scott C. Ambrose Jan 2015

Sales And Operations Planning: A Performance Framework, Scott C. Ambrose

Doctor of Business Administration Dissertations

Despite a robust body of practitioner-oriented literature focused on the importance of balancing customer demand with product supply within companies, there is very little empirical research suggesting how to achieve it. Sales and Operations planning (S&OP) is a tactical approach meant to help firms accomplish demand and supply balance at aggregate levels. While guidebooks authored by consultants suggest best practices that lead to S&OP success, many experts agree that companies have fallen short of achieving the anticipated benefits. Carried out by cross-functional teams, S&OP entails getting people from different thought worlds to work toward a common goal, a challenging task …

Why Empowering Salespeople Is A Double Edge Sword, Lucy Matthews Jan 2015

Why Empowering Salespeople Is A Double Edge Sword, Lucy Matthews

Doctor of Business Administration Dissertations

Salespeople in business-to-business markets are given autonomy to manage firms’ relationships with their customers. This autonomy implies that salespeople are responsible for making decisions that not only benefit but may also adversely impact customers (e.g., offer an account preferential treatment vs. terminate an established account). While numerous studies establish that autonomy (a critical facet of empowerment) has a positive impact on sales employee’s job outcomes, this study investigates the possibility that salesperson autonomy also has undesirable effects on salesperson job outcomes because it makes them responsible for decisions that have adverse consequences on the customers they are charged with satisfying. …

Predicting Doctorate Production In The Usa: Some Lessons For Long-Range Forecasters, Bruce Pollack-Johnson, Burton V. Dean, Arnold Reisman, Alfred R. Michenzi Jan 2015

Predicting Doctorate Production In The Usa: Some Lessons For Long-Range Forecasters, Bruce Pollack-Johnson, Burton V. Dean, Arnold Reisman, Alfred R. Michenzi

Research Reports from the Department of Operations

The nine major independently conducted forecasts of doctoral degree production for the 1970's shared a consistently high bias, although one was quite accurate. In this paper we compare the forecasting models based upon these results and discuss the implications for long-range forecasting. We show that the bias was mainly due to a common core assumption (exemplifying "assumption drag") that students would pursue degrees at clo-se to the existing rates in spite of decreasing traditional demand for graduates. The results also indicate the value of simple models and eclectic forecasting methods, the desirability of robust causal models and dangers of extrapolative …

A Taxonomy Of Mis, David Majd Jan 2015

A Taxonomy Of Mis, David Majd

Research Reports from the Department of Operations

A perusal of the management information systems (MIS) literature or attendance at a major conference calls attention to the diversity of the discipline and the need to have some larger frame of reference in which to understand MIS research. This paper utilizes two MIS research frameworks to demonstrate the role of integrative thought in understanding and guiding MIS research. A literature review is used to support the claim that the benefits of improved recall, more effective hypothesis generation, wiser allocation of research resources and better interdisciplinary communication can result from the use of these frameworks.

Multi-Item Production And Inventory Management Under Price Uncertainty, Bani P. Banerjee, S. Sankar Sengupta, Gifford H. Symonds

Research Reports from the Department of Operations

A model is presented for the derivation and implementation of optimal linear decision rule for a firm producing and dealing in a number of interacting products, and possessing partial influence on their prices. The behavior of a multi-item production-inventory complex is represented as the dynamics of suitably defined state variables under the influence of decision rules that are stable and linear in the state variables, but otherwise unspecified. The dynamical equations are stochastic owing to the presence of stochastic processes in the forcing terms. The statistical properties of these processes, together with the decision rules, determine the statistics of the …

An Update On Barter: Some Contributions Of Management Science, Arnold Reisman, Duu-Cheng Fuh, Gang Li

Research Reports from the Department of Operations

Bartering, humanity's oldest form of commerce, has been practiced since prehistoric times, with evidence dating back to 8300 B.C. This trade system has endured through various civilizations and economic stages, including the post-industrial era. Today, bartering remains prevalent, comprising 30% of global trade, with modern examples like professional sports player trades. Despite its widespread practice, bartering—referred to as "countertrade" in modern terminology—has received minimal attention in Western business education and research. However, this is poised to change, as the U.S. Department of Commerce predicts that countertrade will account for 50% of global trade by the year 2000. This resurgence highlights …

Two Algorithms For Inventory Decisions Under Inflationary Conditions, N.G. Duraiswamy, Arnold Reisman Jan 2015

Two Algorithms For Inventory Decisions Under Inflationary Conditions, N.G. Duraiswamy, Arnold Reisman

Research Reports from the Department of Operations

This paper reports two algorithms for inventory decisions under inflationary conditions. The first, a heuristic algorithm, was designed to provide efficient purchasing decisions when the demand is deterministic and constant overtime and no inventory shortage is allowed at anytime. It is assumed that price increases due to inflation occurs in a discrete fashion; that is, prices go up not continually but at discrete time points. The second, a dynamic programming algorithm was derived under the same price increase assumption, but applies to the deterministic, dynamic demand and no shortage problem.
