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

When Competition Isn't Enough: Rural Health in Southwest Virginia (A)
Matherne; G. Paul; Goldberg; Rebecca; Bermel; Peggy; Fox; Brennan; Minogue; Kevin; Oberleitner; Ryan; Punches; Charlie; Rose; CarolineCase DARDEN-S-0314-EStrategyMark Seidman at the Federal Trade Commission is evaluating a proposed merger between two health care entities and competing market leaders in southwest Virginia. The rural region is characterized by poverty; unemployment; and poor population health indicators relative to the rest of the state. The merger would form a virtual monopoly; normally prohibited by federal consumer protection laws; but the two companies assert that it would allow them to...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

When Competition Isn't Enough: Rural Health in Southwest Virginia (C)
Matherne; G. Paul; Goldberg; Rebecca; Bermel; Peggy; Fox; Brennan; Minogue; Kevin; Oberleitner; Ryan; Punches; Charlie; Rose; CarolineCase DARDEN-S-0316-EStrategyThis optional C case follows S-0314 and S-0315; and describes the results of decisions on whether to allow a merger of two health care entities in rural Virginia. This case set explores the differences in and conflicts among the interests of for-profit health care systems; of rural; low-income residents; and of federal; state; and local governments. It allows students to engage in an in-depth discussion of the sometimes emotional issue of rural h...Starting at €5.74

The Mathematics of Optimization
Carraway, Robert L.Technical Note DARDEN-QA-0683-EDecision AnalysisIn “Introduction to Optimization Models” (UVA-QA-0682), we explored the basics of using optimization models, or mathematical programming. In this technical note, we turn our attention to the mathematics underlying optimization. While not essential, a deeper understanding of the math can help you become a significantly more effective and efficient user of optimization models. It is well worth the investment if you anticipate using optimization on ...Starting at €8.20

Dr. Bronner's: Do Psychedelics Fit with Its Cosmic Principles?
Freeman; R. Edward; King; Adelaide Wilcox; Maiden; Stephen E.Case DARDEN-S-0405-EStrategyThis field-based case describes the situation facing David Bronner, cosmic engagement officer (CEO) of Dr. Bronner’s Magic Soaps (Dr. Bronner’s), the top-selling brand of natural soaps in North America in 2019. Since its founding, the company has centered advocacy for unity and social change in its products and giving. The question before David and the leadership team is whether to extend the brand further by publicizing its support for the use o...Starting at €8.20

Flex Technology
Grushka-Cockayne, Yael; Carraway, Robert L.; Sorenson, TravisCase DARDEN-QA-0811-EDecision AnalysisAfter years of development, William Krause knew that 2014 was the year to “go big or go home.” His Flexible Herbert Screw, a medical device intended to support the healing of fractured collarbones (clavicles), was ready for launch, and he had accumulated the necessary cash-$1 million by his reckoning-needed to comfortably see him through the start-up phase. Although evidence in favor of the invasive device was still inconclusive, other key player...Starting at €8.20
