Engineering >> Mechanical EngineeringPipeline Optimizationby Emily Dutton
Submitted : Fall 2011 The goal of this project was to determine the minimum cost for laying a pipeline that went through land and water. Given that the pipeline in the water cost double the amount of pipeline through land, I had to find the optimal pipe placement to minimum cost. First, I started by finding the equations of lines and distance formulas that varied as the pipe orientation changed. I used these formulas to formulate a cost function which is equal to the total cost of the pipeline construction. By taking the derivatives, I found the critical points, which are the exact coordinates of the pipeline at minimum cost. To prove that these critical points are a local minimum, I used the second derivative test. My conclusions that I made is that the pipeline ascends up to the first coast line, continues in a straight line across the water, and then reaches the other land with a mirror image of the first line. This is the exact route that I pictured before I started the project, but I had to find the exact coordinates and make sure the solution was mathematically correct.
