2. What is industrial engineering? • A commercial reminded me a practical definition • We do not make a lot of products or services you use, we engineer industries more efficient for better and cheaper products, faster responses, easier and more sustainable operations, etc.

3. Definitions of Industry - Webster • 1. Diligence in an employment or pursuit; especially: steady or habitual effort • 2. • systematic labor especially for some useful purpose or the creation of something of value • a department or branch of a craft, art, business, or manufacture; especially: one that employs a large personnel and capital especially in manufacturing • a distinct group of productive or profit-making enterprises • manufacturing activity as a whole <the nation's industry> • 3: work devoted to the study of a particular subject or author <the Shakespeare industry>

4. - Definition by ISyE • Industrial Engineering is a branch that describes, evaluates, designs, modifies, controls and improves the performance of complex systems over time and in their context of • Supply chain systems • Manufacturing systems • Service systems • Financial and economic systems • Health systems • Etc.

5. - Definition by IIE • IEs work in a variety of businesses • IE education offers the best of both worlds: engineering & business (product, service, people and organization) • Shortening customer waiting in theme parks • streamlining an operating room • distributing products worldwide • … • As companies adopt continuous productivity and quality improvement, the need for industrial engineers is growing • They work to eliminate waste of time, money, materials, energy, and other commodities

6. Info from College Board • Career • Develop efficient system to deliver products or services. • You should • Find and solve problems • Know statistics, computers, stochastic process and optimization • Write reports, give presentations and communicate with others • It Helps to Be... • An organizer, a puzzle solver, and someone who loves order • IEs need to listen, explain, and teach • Outlook • Economists predict IEs will grows faster than other occupations through 2016. • More openings because IEs tend to become managers. • Compensation • Starting GT IE is $58,000, May 2008 • Those graduated between 3 and 6 years are $69,886 • The U.S. Bureau of Labor Statistics estimates: average in 2007 as $73,490

Malaria Transmitted by female Anopheles mosquitoes No vaccine available Effects 1-3 million deaths annually worldwide One death every 30 seconds 48,000 deaths in Sudan each year Prevalence continues to increase Health system eg: Malaria Eradication This document was created within the frame work of a student design project and its contents are neither sanctioned by Georgia Institute of Technology nor the CDC.

13. Method and outcomes • Sterile Insect Technique (SIT) • Female mosquitoes mate once in lifetime • Release large numbers of sterile male insects • Desired Outcome • Long term solution for malaria suppression • No environmental or health side-effects • At minimum cost This document was created within the frame work of a student design project and its contents are neither sanctioned by Georgia Institute of Technology nor the CDC.
