AAE55000 - Multidisciplinary Design Optimization

Fall 2016

Days/Time: TBA / TBA
Credit Hours: 3

Learning Objective:
To acquire basic knowledge about engineering design optimization techniques and newer techniques for multidisciplinary optimization; develop proper engineering design optimization problem statements; select which optimization method(s) is/are appropriate for a given application; solve multidisciplinary engineering design optimization problems using a computer and available software libraries/toolboxes (primarily Matlab and Excel); interpret solutions generated by an optimization routine.

Description:
This fast-paced, graduate-level course introduces the techniques of engineering design optimization, leading into topics for Multidisciplinary Design Optimization (MDO). The application of these techniques to solve engineering design problems is also presented. First, students are exposed to basic concepts about and implementations of numerical optimization techniques, assuming that the students have little or no knowledge of these topics. Second, students investigate approaches for multiobjective and multidisciplinary optimization based upon knowledge of the basic techniques.

Prerequisites:
Computer programming skills sufficient to use available functions in Matlab. Knowledge of linear algebra, multivariate calculus, and numerical methods. Some knowledge of basic statics and strength of materials may help with example and homework problems.

Applied/Theory: 65/35

Web Content:
Blackboard will contain: A link to my current course website, syllabus, grades, lecture notes, homework assignments, solutions, quizzes and message board.

Homework:
Course grade is wholly homework and project-based. There are several (about 7) Blackboard-based "assessments", a few (about 3) longer "homework" assignments and 1 "final" project. All assignments to be submitted via the Blackboard course page (available to registered students only).

Projects:
Required. Final project requires individual students to identify a design optimization problem of their choosing and to develop and solve this problem. Project is documented by a short final report. Project can - but is not required to - be related to the student's job.

Exams:
No exams. Note: General student opinion is that the course requires more time for assessments and homework than courses using traditional exams.

Textbooks:
Official textbook information is now listed in the Schedule of Classes. NOTE: Textbook information is subject to be changed at any time at the discretion of the faculty member. If you have questions or concerns please contact the academic department.
Tentative: None required.

Computer Requirements:
ProEd minimum requirements; all projects and assessments include computer work. Students are required to write scripts in Matlab to call toolbox functions. Some assignments use Excel and Solver add-in. Each lecture will use handouts in Adobe Acrobat format; Acrobat or other *.pdf file reader is needed.

ProEd Minimum Requirements: view

Tuition & Fees: view

Other Requirements:
Students must have access to Matlab (Student version okay) with Optimization Toolbox and Excel with Solver add-in. Students have free access to Matlab via Purdue's Software Remote at https://goremote.ics.purdue.edu. The student version of Matlab is reasonably priced, if students want to purchase this.
