Acoustic Emission Testing

63_mBefore acoustic emission testing, oil storage tanks could only be checked for leaks by visually inspecting the inside tank floor. Most companies are usually required to have this done every five years. To do this, all oil in the tank would have to be drained. Following drainage, the whole tank would have to be sandblasted. Inspectors could then go inside the tank and check the floor for damage. This type of damage testing had several draw backs. All the oil that was in the tank upon draining would have to be disposed of; it could not be reused in any way. The price of this procedure could range from 15 to 20 lakh depending on the size of the tank. On top of the high price, the tank itself would be offline and unusable for about 3 months.

AUCNET USA Case Study

7Even though Aucnet Japan is successful, AUCNET USA is losing the interest of dealers of used cars from its satellite auto auction process. Help the management analyze alternatives and come up with recommendations.

Excerpt From Case Study

In 1985, Mr. Masataka Fujisaki, an entrepreneur, saw an opportunity to transform the marketplace of wholesale auto auctions in Japan. In this market, large volume dealers sold and bought cars from other dealers; no sales were made to direct consumers. The vehicles were transported weekly to one of several established locations and sold to dealers at live auctions. This traditional method was inefficient because only about 40% of the inventory were sold at any auction. Mr. Fujisaki envisioned a computerized auction system where the dealers did not have to leave their workplace to buy and sell cars. Therefore, he established an auto auction business utilizing information technologies to buy and sell cars in the wholesale market.

Automatic Weld Inspection

20For the year 2000, welding expenditures in the U.S manufacturing, mining and construction industry was about $34 million. In order to test these welds in a non-destructive manner, nearly half a million radiographs are being produced every year. General Manager-Operations wanted a team at the imaging lab to develop new methodologies to identify defects in welds for analyzing the radiographs.

Chick-Fil-A Case Study

1Fast-food giant Chick-fil-A faced a major decision when the manufacturer of its point of sales (POS) terminal systems stopped producing the EPROM systems it used at the price it originally offered the restaurant. Chick-fil-A was presented with three options from the technology available at the time of the decision:

  • Continue purchasing the EPROM POS systems at an inflated price
  • Purchase and implement POS systems based on Windows CE technology
  • Purchase and implement POS systems based on Windows NT technology

This case study allows students to act as decision makers to select and support a solution based on Chick-fil-A’s business needs and alignment of technology. Students are challenged to evaluate the options based on operational visability, technical architecture, programming effort involved, environment, 5-year total cost of ownership, and business issues.

Climate Response Design

climate_responseWhen a project is brought to a group of competing architecture firms, both quality of design and cost of design are key aspects in winning the job. In order for the architects at Larsen and Toubro (L&T) to have a winning bid, this research into quality and cost must be quickly accessible to the presenting architects.

The Center for Excellence and Futuristic Development, a department at the Chennai branch of L&T has decided that climate should also be taken into consideration when designing smart, sustainable and cost-effective buildings.

Problem Statement

Buildings need to be enchanted by Climate Response Design; learn the charts and variations of options in order to understand Climate Response Design and what it takes to make buildings economically and sustainably sound.
