Introduction to Optimization Models
Carraway, Robert L.Technical Note DARDEN-QA-0682-EDecision AnalysisWe refer to a model that uses mathematical programming to find an optimal quantity as an optimization model. Thus, an optimization model differs from an evaluation model in that it goes beyond simply evaluating the consequences of proposed alternatives: It actually identifies the “optimal” alternative. How does an optimization model accomplish this impressive task? In this age of readily available computing power and ever more user-friendly softw...Starting at €8.20

The Coronet-Cameron Baker
Frey, Sherwood C. Jr.; Colebank, Mike; Bacon, PaulCase DARDEN-QA-0763-EDecision AnalysisThis case and its companion, "The Coronet-Leslie Forsyte" (UVA-QA-0764), are intended for undergraduate, executive education, and MBA audiences. They were written for a "Bargaining and Negotiating" elective. This case is from the perspective of Cameron Baker, who owns a 1970 Dodge Coronet and needs to sell the car.

Cornwell Performance Products
Frey, Sherwood C. Jr.; Bacon, PaulCase DARDEN-QA-0795-EDecision AnalysisIt was May 2007. Earlier in the week, Cornwell Performance Products (CPP), a division of the multinational chemical manufacturer Cornwell, Inc., had notified its largest customer that the price of hydrofluoric acid (HF) would increase at the end of the year. This action was in accordance with an environmental clause in CPP’s contract with Epsilon Refinery Group. The contract provided a 60-day period following notification during which time the pa...Starting at €8.20

Analyzing Uncertainty: Probability Distributions and Simulation
Carraway, Robert L.Technical Note DARDEN-QA-0660-EDecision AnalysisThis note introduces simulation as a tool to analyze uncertainty in business decisions. It first observes the limitations of single point or simple range estimates of key uncertainties, thereby motivating the need to create a risk profile for any alternative that characterizes the full range of possible outcomes and their relative likelihoods. A simple example involving both a discrete and a continuous (triangle) distribution is used. The note is...Starting at €8.20

Jaikumar Textiles, Ltd. (B): The Nylon Division
Carraway, Robert L.Case DARDEN-QA-0391-EDecision AnalysisIn this case, a second constraining resource is introduced to the decision environment of the A case (UVA-QA-0364), making linear programming appropriate and useful. Because there are two decision variables, the problem can be solved graphically. A set of memoranda to the decision maker in the case motivates discussion of a shadow price and its associated range.Starting at €5.74

Dow Chemical U.S.A.: Capacity Expansion
Carraway, Robert L.Case DARDEN-QA-0411-EDecision AnalysisDow Chemical U.S.A. is faced with the decision of where to locate a new chemical reactor. Three current plants sites are being considered. Economic planner John Lewis has been charged with analyzing the impact of the reactor location on distribution costs. Though not suggested in the case, it is possible to construct a linear programming model to assist him in his analysis.Starting at €8.20

Wausau Equipment Company: A Lean Journey (B)
Landel, Robert D.; Gruia, SorinCase DARDEN-OM-1382-EService and Operations ManagementThe lean initiative detailed in the (A) case, OM-1354, had reached a precarious stage. The machine and systems division of Wausau Equipment Company (WECO) had failed to sell several harvesting systems to customers to usually reliable buyers, and the competition was making important inroads in what was traditionally WECO country. The first wave of improvements made by the teams had not yet had any impact in the field. Enthusiasm to re-engage in th...Starting at €5.74
