What do you think industrial engineers do?

Pre-Class Friday 9-7-12

During the recent Dezzlup Cup, the first four horses did well to finish ahead of the opposition. After Dinner was not last and the horse wearing blue was not third. Bitter Twist was before the horse in green. Dare Devil came first. Bitter Twist finished before After Dinner. Catch Me wore red but Bitter Twist did not wear yellow. Can you determine where each horse finished and the colors they wore?

Thinking back to the presentation by our guest speaker on Friday, what new thing did you learn about Civil or Traffic Engineers that you did not learn from

class (or know already)?

Industrial EngineeringIndustrial Engineering“the design, improvement and

installation of integrated systems of people, material and energy”

“Engineers make things. Industrial engineers make things better.”

What is an industrial engineer?

• To combine workers, machines, and materials in order to increase productivity and reduce waste

• Involves integration of technology, mathematical models, and management practices

• New machines that started the Industrial Revolution were invented by, what we would call, industrial engineers

• Average salary in 2005: $49,678 (2011: $77,090)• Starting salary in 2009: $55,067 (bachelor’s only)

A Closer Look…(p. 69, 70)

• Four basic areas:– Production: plant layout, scheduling, optimization– Manufacturing: individual production– Human factors: interface of people to people or

machines (ergonomics)– Operations Research: optimization of systems

(Project Manager)• Divisions of Industrial:

– Aerospace and defense– Facilities Planning and Design– Manufacturing– Quality Control and Reliability– Utilities

Stress Analysis (page 49)• Objective

– Determine employee health within the factory• Materials

– Stopwatch, backpack, books• Procedures

– Follow what is listed in the book• Questions

– What relationship do you see between heart rate and each situation?

– List and describe 3 improvements that could be made to help factory employees? Remember, it needs to be helpful to the employee and not a burden to the employer.

Lines at Amusement Parks

Problem– How to reduce the wait time at amusement parks

Materials– Computers/cellphones

Procedures/Questions– Find a roller coaster-type ride in an amusement park that everyone

has ridden or at least knows what it looks like.– What type of data do you need to know to reduce the wait time?– Are there problems with the line system being used now? Explain.– What will decrease the wait time? Explain.– Are there design improvements for the wait line? Explain.– To make any changes will involve many groups, describe what

would have to take place.

Pre-Class Wednesday 9-12-12Pre-Class Wednesday 9-12-12Costume Party Fiona, George, Rachel, and Patrick are planning their costumes for a party. Each will wear a different costume. There will be a pirate, a ghost, a Martian, and a gorilla.- No one will have a costume that begins with the same letter as the name of the person wearing it. - The Martian is a boy. - The gorilla is a girl. - Patrick likes science fiction and space characters. - Fiona didn't want to be a ghost this year.

Which costume will each of the party-goers wear?Fiona will be the gorilla. George will be the pirate.Rachel will be the ghost. Patrick will be the Martian.

Systems EngineeringSystems Engineering

• Work with the overall design, development, manufacture, and operation of a complete system or product

• Responsible for integration of the product’s components

• Interface between each engineering group to meet customer specifications

Production Floor Efficiency

• Materials– Rolling cube– Deck of cards

• Objective– Improve the efficiency of

a manufacturing business

• Procedures– Groups of 6 (5 minimum)– Designate roles based on

next slide– Attempt to complete the

task before other groups

Floor Production RolesFloor Production Roles

1. Production

2. Runner

3. Sorter

4. Mover

5. Finisher

6. Recorder

• Starts with shuffled deck, flip 5 cards• Only have 5 cards showing at once• Deliver face cards 1-at-a-time from #1 to #3• Deliver # cards 1-at-a-time from #1 to #5• Roll even: do nothing• Roll odd: match A,K,Q,J in suites (1 card)• Move face sets to outbox (1 set at-a-time)• Move # sets to outbox (1 set at-a-time)• Roll even: stack red (1 card at-a-time)• Roll odd: stack black (1 card at-a-time)• Record times, improvements, and answers

Getting Better

• Record the time it takes to complete your task.• Repeat task, but everyone must have a different job.• Record the time it takes to complete your task a second

time.• Make and record one adjustment to improve your time.• Repeat task, but everyone must have a different job.• Record the time it takes to complete your task a third

time.• Finally, make one more improvement, record it, change

roles, and repeat one final time.• Record the time it takes to complete your task a fourth

time.

Analysis

1. Did your improvements lessen the time to complete the task?

2. What area/role was the biggest hold-up?

3. Did every area/role work equally?

4. Was your industrial team successful? Explain.

You are on your way to visit your Grandma, who lives at the end of the valley. It's her birthday, and you want to give her the cakes you've made.

Between your house and her house, you have to cross 7 bridges, and as it goes in the land of make believe, there is a troll under every bridge! Each troll, quite rightly, insists that you pay a troll toll. Before you can cross their bridge, you have to give them half of the cakes you are carrying, but as they are kind trolls, they each give you back a single cake.

How many cakes do you have to leave home with to make sure that you arrive at Grandma's with exactly 2 cakes?

The Product

• Each group will need three sets of plans: one for me and one for two other groups.

• Groups will split into plane-only and box-only.

• Groups will build each at the same time.

• To turn-in:– Your set of plans– Your positive comments on their plan– Your negative comments on their plan

Note: there cannot be more negative than positive comments
