SA305 Spring 2015 Submarine detection project, part 2 GMPL Code your formulation into GMPL. Using the two data sets in the excel sheet MDRData.xlsx, solve the model and save the two outputs. Duality For your model from the previous part of the project, take the dual. ‘ Discussion Answer the following questions. 1. Interpret the dual that you took. In particular, what could the dual variables represent? 2. In the data given, two new depths for sonic buoys are presented, 600’ and 800’. Solve your model without these two depths (it is easiest to create two new .dat files). Based on your results, discuss whether the Navy should consider these two new depths. Be sure to consider the impact of the different sonic layer depths as well as the differing optimal objectives. Hand in your code, dual formulation, and discussion by the last day of classes. The discussion should be typed in Word or similar word processor.
