1. Evaluar los cambios Dore Dore tiene loco en la división de géneros de punto de sus hijos. ¿Cómo funciona el rendimiento de la operación tradicional y el sistema de fabricación celular difieren? (Para evaluar las diferencias entre los dos sistemas, se supone que prenda un promedio de los niños requiere 10 operaciones, y que una el tiempo de producción de una prenda de vestir en tejidos de punto es de 3 horas.) Por ejemplo, ¿cómo cambio en el inventario de trabajo en proceso cuando las células se implementan? ¿Qué cambios son necesarios para asegurar la implementación exitosa de manufactura celular? Es a través del entrenamiento necesario trabajador?

2. ¿Cuál es la motivación de Dore Dore para convertir a las células? En el supuesto de continuar con sus planes para la implementación completa de las células en los géneros de punto de los niños? Si no es así, que las prendas de punto (en su caso) debe ser fabricado en las células?

3. Si Dore Dore implementar las células en su área de producción medias? Si es así, ¿podría sugerir cambios en el diseño de las celdas como se propone actualmente por M. Enfert? Si no, ¿qué otros enfoques podrían Dore-Dore tomar para hacer frente a la preocupación M. Marguet plantea en el caso?

* Método tradicional:

Unidades de avance / día = 2.000 unidades

Tiempo de procesamiento = 15 días

El trabajo en curso = 30.000 unidades

Número de trabajadores = 42

WIP / trabajador = 30000/42 = 720 unidades

* Método Celular:

Unidades de avance / día = 2.000 unidades

Tiempo de procesamiento = 1 día

El trabajo en curso = 2000 unidades

Número de trabajadores = 42

WIP / trabajador = 2000/42 = 48 unidades

Dado que el tiempo de ciclo = rendimiento tiempo / trabajo en curso, por lo que el tiempo de ciclo de operación tradicional es 3 * 5 * 8 * 60/720 = 10 min y el tiempo de ciclo de operación celular es 1 * 8 * 60/48 = 10 min. A continuación, el producto por trabajador sigue siendo el mismo.

...Carlos Weller Dore Dore La familia Dore comenzó un negocio de ropa en 1819. Poco a poco logró su éxito y se convirtió en uno de los nombres mas reconocidos mundialmente en las medias de alta calidad. Dore Dore entonces estableció una línea separada de ropa cocida(Knitwear). Marguet se convirtió en el nuevo director de operaciones llevando a DD a un nivel mas alto. DD sobresale ante las demás marcas y se diferencia por su servicio al cliente para los clientes de las medias. Lead times largos era comunes en la insutria de la ropa. Dore Dore ha tenido muchos problemas debido a los desajustes que se han tenido en la producción y la verdadera demanda de los productos, asi que Marguet empezó a investigar estrategias de respuesta rápida. Marguet came up with a supply chain divided in upstream as manufacturing and downstream as retail. La fabrica de medias produce básicamente calcetines y la división de ropa cocida produce básicamente ropa de niño. La producción era 37,000 pares de calcetines y 2000 articulos de niños cada día. Para tener un pronostico de la demanda DD se basaba en intuición, ya que los tiempos de lead time eran tan largos y no se podía saber que demanda iba a tener los artículos, lo cual provocaba que DD manejara altos inventarios y por ocaciones no pudiera vender a tiempo los artículos, teniéndolos que rematar la siguiente temporada a menor tiempo. Basicamente lo que Marguet planteo fue bajar los lead times, basando los replenishments en data......

...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......

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...

...CASE STUDY 2 I. THE ARALIN TEACHER Mrs. Boots De Vola was assigned to teach the first section in third year level. She assumed that she is an effective and efficient teacher in Araling Panlipunan because of that. There are many teachers qualified and much deserving to teach the star section. Now, the students are complaining of the expenses regarding projects, special projects and the way she behave in classroom. II. HISTORY AND BACKGROUND OF THE FACTS Mrs. Boots De Vola have underwent the process of being LSB teacher, PSB teacher, before she was declared as regular teacher in Banana National High School. It has been five years that she handled Aralin in section one. There are congruency on each year complaint but since the students are afraid of failing her subject they remained quiet. I seldom hear news about her projects and the money she collected from her advisory class. Every single mistake has an specified amount to be collected as fine, but the students don’t know where these money will be spent. Another concern about Mrs. Boots De Vola is the way she handled and treated her students. She always nag and shout to students, for her it’s the way of disciplining her students. Some of the students chose to dropped schooling because they felt being degraded and they do not have money for everyday fine. Lately, a mother asked her about the special project of her son amounting one hundred thirty pesos. The project was properly discussed, but we found out that......

...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......

Essay About Gustav DoréS Picture

...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......

...A few tips from Bain & Company: • • • • • Don't get thrown by the interviewer's questions. The interviewer is your ally and uses questions to get a better understanding of your thought process--not to stump you. Be concise. If asked for the top two issues, confine your response to two items. Provide logical back-up for your answers. Be sure to explain what case facts led you to a conclusion, and how you reasoned from those facts to your conclusion. Don't be afraid to ask clarifying questions. If you don't understand the case facts, it will be tough to ace the interview. Relax and have fun. You should learn a lot about yourself through the case interview process. A few tips from Mercer Management: • • • • There is no "right" answer. We are not looking for a specific answer. We are trying to gain some insight on your thought process. Ask questions. We do not expect you to know anything about the industry presented in your case. We do expect you to ask good questions. Think out loud. The point of the case interview is to understand how you think. Structure your answer. We're looking for an organized pattern of thought to attack the problem, not a disparate set of ideas. Help us see how you order your thoughts and ideas, moving from one to the next in order to address the question. While use of a framework may be helpful in this area, be careful if you use one. We want to understand your thought process, not see that you've memorized someone else's framework. (And never use a......

Dedicated to generating clean energy, 80 % of its capacity is fueled by clean and renewable resources. The United States is the nation with the largest generator of wind energy, and it operates the two largest solar fields in the world. FPL Group, with annual revenues of more than $8 billion, is one of the nation's largest providers of electricity-related services. Its principal subsidiary, Florida Power & Light Company, serves approximately 3.9 million customer accounts in Florida. FPL Energy, LLC, and FPL Group energy-generating subsidiary, is a leader in producing electricity from clean and renewable fuels. 2. Historical Overview FPL Group is a far different company today than the one Jim Broadhead joined in January of 1989 when he became president and chief executive officer. FPL Group was then engaged in a number of businesses unrelated to its core electric skills, including insurance and financial services, real estate, cable television, and agriculture. The company's principal subsidiary, Florida Power and Light, was considered a well-managed utility with an emphasis on quality. However, the utility's spiraling costs had resulted in electric rates among the highest in the Southeast. Today, FPL Group is nationally known as a high quality, efficient, and customer-driven organization focused on energy-related products and services. With a......
