Product and Production Relations in Computer Integrated Manufacturing
The following assignment for Computer Integrated Manufacturing involves Product and Production Relations. You should answer the following questions and bring in the next class.
Questions

1. A plant produces three product lines: A, B, and C. There are 6 models within product line A, 4 models within B, and 8 within C. Average annual production quantities of each A model is 500 units, 700 units for each B model, and 1100 units for each C model. Determine the values of
(a) P and
(b) Qf (total production quantity of all products made in the factory) for this plant.
2. The ABC Company is planning a new product line and will build a new plant to manufacture the parts for a new product line. The product line will include 50 different models. Annual production of each model is expected to be 1000 units. Each product will be assembled of 400 components. All processing of parts will be accomplished in one factory. There are an average of 6 processing steps required to produce each component, and each processing step takes 1.0 minute (includes an allowance for setup time and part handling). All processing operations are performed at workstations, each of which includes a production machine and a human worker. If each workstation requires a floor space of 250 ft2, and the factory operates one shift (2000 hr/yr), determine
(a) how many production operations,
(b) how much floorspace, and
(c) how many workers will be required in the plant. Note: Neglect the effect of assembly time.
3. The XYZ Company is planning to introduce a new product line and will build a new factory to produce the parts and assembly the final products for the product line. The new product line will include 100 different models. Annual production of each model is expected to be 1000 units. Each product will be assembled of 600 components. All processing of parts and assembly of products will be accomplished in one factory. There are an average of 10 processing steps required to produce each component, and each processing step takes 30 sec. (includes an allowance for setup time and part handling). Each final unit of product takes 3.0 hours to assemble. All processing operations are performed at work cells that each includes a production machine and a human worker. Products are assembled on single workstations consisting of two workers each. If each work cell and each workstation require 200 ft2, and the factory operates one shift (2000 hr/yr), determine: (a) how many production operations,
(b) how much floorspace, and
(c) how many workers will be required in the plant.
4. If the company in Question 3 were to operate three shifts (6000 hr/yr) instead of one shift, determine the answers to (a), (b), and (c).

Turkish First lady interviewed by The Times
Hayrunnisa Gul, the wife of President Abdullah Gul, underlined in an interview with an English newspaper that it is her head she covers with the Islamic headscarf — not her brain.
Hayrunnisa Gul, the wife of Turkish President Abdullah Gul, underlined in an interview with an English newspaper that it is her head she covers with the Islamic headscarf — not her brain.

The first lady, who was interviewed by Janice Turner of UK daily The Times, said she did not believe headscarves should be forced on women.

“To me, women should not be forced to wear headscarves. It would be hard to find anyone in İstanbul who would disagree with me, at least in public,” Mrs. Gul was quoted as saying.

Gul’s interview was published yesterday in Times2, The Times’ main supplement, which features various lifestyle columns.

The headscarf issue is a topic of fierce debate in Turkey, where wearing the Islamic headscarf is banned in the public sphere.

Its use at universities was prohibited in the late 1990s through an earlier ruling by the Constitutional Court on the grounds that it would violate the nation’s secular principles, as the headscarf was seen as a political and religious symbol.

It was stressed in the Times2 article that the headscarf, worn by a considerable portion of Turkish women, means more in Turkey than in any other country.

“It has become the most potent symbol of a battle for the soul of the country that will determine its place in Europe and the Islamic world,” the article stated.

The article also recalled a closure case filed against Turkey’s ruling party.

“Despite the solid parliamentary majority that enabled her husband [Abdullah Gul] to become president, the country’s Constitutional Court is determined to press ahead with a case intended to outlaw the ruling Justice and Development Party [AK Party] and ban its leading members from politics,” it said.

A top prosecutor requested in March that Turkey’s Constitutional Court close the governing AK Party and place a ban on political party involvement for 71 of its high-level officials, including Prime Minister Recep Tayyip Erdogan and Gul, who was an AK Party member before becoming president and severing political ties as required by the Constitution.

It was also expressed in the article that Western governments must see this case for what it is — an attempted judicial coup.

“It has scant legal basis. If successful it would derail Turkey’s already fraught EU accession and lead many AK Party supporters to despair of the ballot box,” the article read.

Quiz on Europe in Turkey
There has been a recent project with the title “Quiz on Europe in Turkish high schools”.
Quiz on Europe in Turkish high schools
The 2008 edition of the quiz on Europe, recently launched in Turkey, is going to be a success. The quiz involved more than 400 high schools.

The 2008 edition of the quiz on Europe, recently launched in Turkey, is going to be a success.

The quiz involved more than 400 high schools in Beyoglu (26), Umraniye (25), Pendik (23), Bahcelievler (23) and Kadikoy (22).

The students’ competition, which will last for two months, has the purpose to stimulate study and research on the issues which concern the European Union.

The finals will be held in Ankara in May.

“After the success of the 2007 edition, we have extended the contest to 15 cities, reaching also Van, with the support of the Education Ministry and the Info Network of the EU”, the director of the European information centre Aybige Tanriover said.

The schools of Istanbul started the preparation stage of the quiz at the beginning of March.

The European quiz is organised by the Education Ministry, delegation of the EU in Turkey, and the European information centres spread throughout the country including Adana, Antalya, Bursa, Denizli, Diyarbakir, Edirne, Gaziantep, Izmir, Kayseri, Mersin, Samsun and Van.

The winning class will go on a trip to Brussels and Berlin in June 2008.

Youngest Professor of the World
Girl, 19, whose name is Alia Sabur, becomes youngest professor of the world.

Iranian but US citizen Alia Sabur, 19, has been announced the world’s youngest full-time professor in history by the Guinness Book of World Records, media reported.

The former child prodigy, clarinet maestro, black belt martial artist and budding scientist has been named the world’s youngest professor.

Miss Sabur will begin teaching physics at Korea’s Konkuk University next month, breaking a record set by Scottish mathmetician Colin Maclaurin three centuries ago, reports the Times.

However, the achievement will come as little surprise to her friends and family. Miss Sabur has been exceeding expectations since infanthood.

She gained a university graduate by 10, a masters at 17 and managed to squeeze in becoming a concert clarinetist with the Rockland Symphony Orchestra - aged 11.

Miss Sabur says her secret is curiosity.

“I just wanted to know how things worked,” she told the paper.

“My parents encouraged me in anything I wanted to do.”

But her gift is not without its drawbacks. By five she had outgrown her friends and moved on to secondary school, where her intellect singled her out as a misfit.

When she went to Stony Brook University in New York aged 10, she took her teddy bears to physics classes.
