	Design Optimizing Expert System

These examples begin where the Global-OPT examples left off and highlight some of the additional features and functionality of Global-OPT's big brother, Multi-Objective-OPT including its embedded database, it's support of more than 5 variables as well as the ability to request more than one solution.  We provide downloadable problem files as well as a link to flash examples where we demonstrate Multi-Objective-OPT's capabilities.

	2-Bar Linkage Position Task: The objective of this Task is to determine the angles Theta1 and Theta2 that will position the indicated location of the second bar labeled B2 at the X,Y coordinates (4,1). You can use Global-OPT to “Minimize” the location error OBJECTIVE in cell B27 to solve this problem. Or you can use Multi-Objective-OPT and specify two Objectives, Match X=4 and Match Y=1. Global-OPT will give you one solution stored in the worksheet and Multi-Objective-OPT will provide both solutions in its Status display with the best one stored in the spreadsheet.

	Gearbox Design Optimization Task: This is a multi-objective discrete variable design optimization task. It is a discrete problem because its four design space variables are the number of teeth on the four gears which all must be integers. There are 3 Objectives for this Task. The first Objective is to closely Match the overall gear ratio of the gear box to an ideal value of 6.931 to 1. However, acceptable overall ratios can fall between 6.7 and 7.2 if necessary to achieve all of the objectives of the task. The second Objective is to decrease the overall width of the gear train with a Target value of 18 cm. The third Objective is that the lower limit on clearance between the outer edge of Large Gear 1 and the center of the shaft for Large Gear 2 is 1.7 cm. This problem requires Multi-Objective-OPT.

	Combustion Curve Fit: A well known method to produce a close approximation to the burn event in an engine's cylinder is to derive two coefficients know as 'Wiebe ' coefficents. Use Multi-Objective-OPT to see just how easy and accurate this process can be!. Download the Combustion Curve Spreadsheet
