Background Dore Dore was established by Jean Baptiste in 1819 It was the world class manufacturer of fashionable knitted products Its hosiery division produced socks and stockings for men, women and children & accounted for 88% of DD’s sales Its knitwear division produced a line of children's knitwear such as play clothes, sweaters and nightclothes. It focused on both quality and fashion It produced hose not only under its DD trademark, but also for famous designers. DD commented a 30% to 40% market share in this segment One of DD’s competitive strengths was its superior customer service for hosiery. * 3. Operations & Problems & Planning. Its operations were divided between two main sites – MERY PLANT, which encompasses all children’s knitwear operations; and GRES COMPLEX, which encompasses the company’s headquarters and central hosiery factory. Each season DD produced each style in two seasons in hosiery and preset production for Knitwear division. Forecasts were uncertain; all production took place before observing consumers demand in Hosiery Division. High inventory costs were incurred. Many items were left unsold. The company wanted to get into Cellular Design Layout for better Production And Operational Utilization. (for instance Part A & Part B shown below) * 4. COMPANY’S DESIGN LAYOUT (Part A) In children’s knitwear division, the company is using presently...

...1. Evaluate the changes Dore-Dore has made in its children's knitwear division. How does the performance of the traditional operations and the cellular manufacturing system differ? For example, how does work-in-process inventory change when cells are implemented? Traditional Operations: Under traditional operations, Doré-Doré’s production batch size in sewing, on average, was 200 pieces of the same style and color, with an average of eight different sizes within a batch. The knitwear sewing contained 55 sewing machines installed and was staffed by 42 workers (Exhibit 7). The additional machines were either specialty machines used for occasional operations or extra machines used in periods of peak demand. The sewing machine operators worked eight hours per day, five days per week. Sewing an average knitwear garment took 10 minutes of actual labor. Cellular Manufacturing: Cellular manufacturing significantly reduced many types of waste present in the traditional sewing process and resulted in delivery time falling from 15 days to 1 day. Given a flow rate of 2,000 garments per day work-in-progress fell from 30,000 to 2,000 units, improving annual work-in-process turns from 16X to 240X. According to Exhibit 4, the work-in-progress inventory fell by an estimated 1.23FF million and holding costs by 275,000FF . Comparison: The grid layout by machine type of the traditional system took no account of garment dependent workflow variability and resulted in the unnecessary movement of...

Its hosiery division produced socks and stockings for men, women and children & accounted for 88% of DD’s sales. Its knitwear division produced a line of children's knitwear such as play clothes, sweaters and nightclothes. It produced hose not only under its DD trademark, but also for famous designers like Yves St.Laurent, Nina Ricci and Chantal de Thomas.DD commanded a 30% to 40% market share in the high end hosiery segment. Operations Its operations were divided between two main sites – MERY PLANT, which had all children’s knitwear operations; and GRES COMPLEX, which had the company’s headquarters and central hosiery factory. Currently they are facing problem of high manufacturing lead time and high inventory. For e.g. in Mery Plant lead time is three months. This increases risk of forecasting and change in fashion. So they are changing current layout to cellular layout to decrease manufacturing lead time (MLT). Mery Plant- Knitwear operations In children’s knitwear division, the company is presently using a product and process design layout to do the operations in the production. In sewing operation they are using product layout. Sewing operation consist of 42 workers 55 machines. As an experiment they have designed one cell with 6 workers which resulted into decreased in MLT from 3 weeks to 1 day. They can make 6 such cells as they...

...1. Evaluation of the Changes that Dore Dore has made to its Children’s division The use of cellular manufacturing in the Children’s division would generally bring about greater efficiency for the following reasons. First and foremost, it would save time by reducing transfer time. Given that the production machinery would be clustered together in a cell, transfer of work-in-progress along the production line would be much faster. Second, in a cellular system the workers are generally cross-trained. This allows greater utilization of the human resource at hand and thereby reduces worker idle time significantly. Third, given the cross training of worker, a bottle-neck is less likely to occur or be a problem. Whenever work-in –progress starts accumulating in a particular operation, the cross trained workers would be able to help prevent the creation of a bottle-neck. To surmise, cellular production would be largely beneficial particularly since it would drastically decrease the flow time. However, it has to be recognized that the cellular manufacturing layout would also entail costs. First, there would have to be multiple machinery that would have to be acquired as now machines would not be shared according to the task performed. Acquisition of new machines would certainly be costly. Second, another related disadvantage would be that there would be greater idle time experienced by the machines and consequent inefficient use of the machines. Third, it is also necessary to be cognizant...

...Gustave Doré was a French artist and one of the most prolific and successful illustrators of the late 19th century, whose vivacious and eccentric fantasy created immense, dreamlike scenes, extensively, followed by Romantic academicians. He was an accomplished painter, but also an engraver, watercolourist, and sculptor who worked primarily with wood engraving. Moreover, however, Gustave Doré is celebrated for his extraordinary talents as an illustrator with an unrestrained imagination, the inventor of places and fantastic beings, a pioneer of comics and a source of inspiration for brilliant filmmakers. Doré's tremendous skill is also involved in various genres, from satire to history. He gave, in turn, enormous paintings and more intimate canvasses,...

...Essay about Gustav Dorés picture US’ sentences and capital punishments The picture is called ‘Exercise Yard’, and is made by Gustav Doré in 1872. The picture illustrates a flock of prisoners walking around in a circle at Newgate Prison in London. In the time the picture was made, London also had capital punishment and rough prison sentences. In the US some states still have capital punishment - for example California, Texas, Tennessee and Florida etc. Many states have abolished it, but it still exists, especially in the US. Capital punishment is in debate and discussion all over the world, and it has always been a taboo as everyone knows they are going to die someday, but apart from that we do not know anything about death, and many people fear it. Capital punishment was repealed in 1972 because of an innocent man who were charged with death penalty for a murder he did not commit. Four years later in 1976 capital punishment got re-established and today in year 2016 the US still has it. As I said before there are many different opinions and arguments for and against capital punishment – so it is basically impossible to define whether it is wrong or right. Some people believe that death penalty is a good punishment to have in society. These people believe that if you do something horrible, for example kills a significant or major person, you are not suitable for the society and you have to “kick the bucket” and evaporate from the surrounding world. It is not only political...

Relevant decisions range from how much material to order for making a product, to determining how much capacity is needed to provide a good level of service, to evaluating which technology will best meet a company's needs. In short, this course focuses primarily on developing and applying tools and techniques to ensure that the right products and resources are at the right place at the right time so as to maximize profit within a business process or supply chain. The “products” could be either goods, services, or both; and the “resources” could be either material, people, money, information, or any combination of the four. In the first part of this course, we will focus on process design and improvement issues by studying the relationships between key process parameters such as capacity and throughput, and by analyzing processes in order...

...Economy. In Shinohata, we see an excellent portrayal of a Japanese village from the perspective of Ronald Dore a British sociologist who visited the village in 1955 and again in 1970. The village is of course named Shinohata and in 1955, Dore writes of a town of largely self-sufficient farmers just recently weaning itself off a feudal land-lordship system, “I wanted to find a village in central Japan with several landlords of medium-sized holdings, in an area where forestland played a larger part in the village economy [forestland was exempt from the land reform].” By all indications Shinohata was what one might imagine a rural village to be not many luxuries, no real technological integration, and not terribly easy to reach. Enter the Japanese City in the same period a rapidly growing and urbanizing force to be reckoned with, “the driving force for postwar urbanization was the growth of heavy industry, [but after the 1964 Tokyo Olympics] employment in construction, wholesale and retail sales, services, finance, real estate, and public service has increased relative to manufacturing. The population engaged in primary industry dropped drastically, from...

...August 20, 2015 3.2.13 Practice: Revision Strategies The tempest one of the most difficult Shakespearean works in my opion to stage, from its stormy, chaotic first scene to its sureality to its ambiguous resolution, with Prospero facing his silent, treacherous brother and renouncing the power that has made every action in the story possible. Potent language remains the central force and mystery of this fathomless play. Prospero speaks almost a third of the lines in The Tempest, and controls the amount of speech every other character on the island has through manipulation and magic. Prospero’s narrative of how he came to the island, what he did once there, and what he is owed for this history, goes largely unchallenged in the text. Yet the play offers innumerable readings and opportunities for alternate staging, particularly in light of postcolonial discourse about Prospero’s relationship with Ariel and Caliban, the legitimacy of his authority, and the nature of his magic and command over language. Though Prospero can be played many ways, there is no doubt he is The Tempest’s show runner. The metatheatrical nature of the play sometimes detracts from its action on the page, but it also offers the chance to explore exactly why Prospero needs an audience for his revenge, and whether or not it satisfies him, onstage. Prospero restricts the sight and knowledge of the other characters, putting them to sleep or manipulating them with invisible forces, but he often lets us, the audience...
