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

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

Mexico: From Crisis to Reforms and from Reforms to Crisis
Saffie, FelipeCase DARDEN-GEM-0205-EEconomicsAs he prepares for a 2023 meeting of General Electric Corp. (GE), Vladimiro de la Mora, president of GE Mexico, weighs the potential benefits and risks of nearshoring production to the Mexican border. Along with major ports that accessed both the Pacific and Atlantic Oceans and a 2,000-mile frontier shared with the United States, Mexico has a long history of trade and cooperation with the United States, supported by trade agreements and low labor...Starting at €8.20

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

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

Determinants of Economic Growth: Supplemental Note
Saffie, FelipeTechnical Note DARDEN-GEM-0204-EEconomicsThis note works best when paired with two other Darden technical notes: "The IS/LM Model" (UVA-GEM-0126), and a note that directly supports this one, "Determinants of Economic Growth" (UVA-GEM-0202). This note provides a formal mathematical derivation to address recurring questions about the Solow model (see GEM-0202 for details). Using a detailed derivation that starts from the investment equation used in UVA-GEM-0126, it shows why population g...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
