An Introduction to Linear Programming Steven J. Miller∗ March 31‚ 2007 Mathematics Department Brown University 151 Thayer Street Providence‚ RI 02912 Abstract We describe Linear Programming‚ an important generalization of Linear Algebra. Linear Programming is used to successfully model numerous real world situations‚ ranging from scheduling airline routes to shipping oil from refineries to cities to finding inexpensive diets capable of meeting the minimum daily requirements. In many of these problems

fabric purchased from another mill. Fabrics that cannot be woven at the Southern Mill because of limited loom capacity will be purchased from another mill. The purchase price of each fabric is also shown in Table 1. MANAGERIAL REPORT I. - Develop a Linear Programming Model that can be used to schedule production for the Southern Textile Mill‚ and at the same time to determine how many yards of each fabric must be purchased from another mill. The model should be clear and complete.

use separate cells to represent decision variables‚ create a formula in a cell to represent the objective function and create a formula in a cell for each constraint left hand side. Once the model is implemented in a spreadsheet‚ next step is to use the Solver to find the solution. In the Solver‚ we need to identify the locations (cells) of objective function‚ decision variables‚ nature of the objective function (maximize/minimize) and constraints. Example One (Linear model): Investment Problem Our

The question we where asked by Professor Gilbertson‚ was to focus on a decision and evaluate it using any two of the following biases that where listed below. I chose availability heuristic biases related to representative heuristic. The availability heuristic is based upon convenience.The simplest heuristic to us is based upon available memory(Tversky and Kahnemann‚1973).What people remember will often guide their decision. Like anyone who has touched a hot stove will remember to avoid repeating

highly trained engineers and managers. NASA is world-renowned for having the best and brightest minds across the industry and as teams reviewed data from the launch‚ they were making decisions based on their experience‚ knowledge of the aircraft and what the initial data reported. They had no reason to believe they were making a tragic error by enabling the space shuttle Columbia to re-enter the Earth’s atmosphere. In an essay‚ Malcolm Gladwell gives this phenomenon a name: “creeping determinism”

PROBLEM NUMBER 1 A farmer can plant up to 8 acres of land with wheat and barley. He can earn $5‚000 for every acre he plants with wheat and $3‚000 for every acre he plants with barley. His use of a necessary pesticide is limited by federal regulations to 10 gallons for his entire 8 acres. Wheat requires 2 gallons of pesticide for every acre planted and barley requires just 1 gallon per acre. What is the maximum profit he can make? SOLUTION TO PROBLEM NUMBER 1 let x = the number of acres of wheat
