Where I Work :: essays research papers

Where I WORK (Case #1) The New York Stock Exchange (NYSE) was established as a place for people to buy or sell stocks. It was started in May of 1792 underneath a buttonwood tree on Wall Street. The expansion of the ideas and dreams of the 24 men is the reason why I have a job today. I would like to share with you the inside of the NYSE from an employee’s point of view. At the NYSE there is a division called Securities Industries Automation Corporation (SIAC), I am an online lead operator. I am responsible for the monitoring, troubleshooting, and resolving of online issues pertaining to the many host system (other computers) that interact with the New York Stock Exchange. I work in the Switching and Order Processing section, whose sole purpose is to maintain zero (0) down time for all of the equipment of the exchange. By this I mean making sure all the computers, printers, handheld devices, overhead screens, etc. are all connected to its proper ports and they are up and functioning properly. In addition to that the department has to keep track of all the orders that are handled through the exchange and check the orders integrity as governed by the Securities and Exchange Commission (SEC). The NYSE must also meet the operational requirements of the member firm (the companies that trade on the NYSE floor). The organizational culture of my company is set by the rules and regulations of the Securities and Exchange Commission. Due to the SEC’s constraints it is difficult to change the culture. According to the 7 dimensions of organizational culture I would rate my company as such: 1.  Ã‚  Ã‚  Ã‚  Ã‚  Innovation and Risk Taking – (rating 1) Due to the restraints and standards set by the SEC there is little room for this. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Attention to Detail – (rating 5) This is the platform on which the organization is structured. 3.  Ã‚  Ã‚  Ã‚  Ã‚  Outcome Orientation – (rating 5) the organization is â€Å"Procedure Driven† but the wrong outcome could affect the entire investment community. 4.  Ã‚  Ã‚  Ã‚  Ã‚  People Orientation – (rating 2) Due to the rules and compliances. 5.  Ã‚  Ã‚  Ã‚  Ã‚  Team Orientation – (rating 5) This is a very important dimension of the organization. For a project to succeed it needs the contribution of different resources. 6.  Ã‚  Ã‚  Ã‚  Ã‚   Aggressiveness – (rating 3) As in most organization there is a need to climb the corporate ladder. 7.  Ã‚  Ã‚  Ã‚  Ã‚  Stability – (rating 5) Because of the ever-increasing demands of the many customers. As an employee of the New York Stock Exchange for over 13 years, I have observed much of the organization’s culture.

Production & Operations Management–Homework 1 for Section 4 Due Tuesday October 16, 2012 1. 1 Eastman publishing Company is considering publishing a paperback textbook on spreadsheet applications for business. The ? xed cost of manuscript preparation, textbook design, and production setup is estimated to be $80,000. Variable production and material costs are estimated to be $3 per book. Demand over the life of the book is estimated to be 4,000 copies. The publisher plans to sell the text to college and university bookstores for $20 each. a. What is the breakeven point? b. What pro? t or loss can be anticipated with a demand of 4,000 copies? . With a demand of 4,000 copies, what is the minimum price per copy that the publisher must charge to break even? 1. 2 Creative Sports Design (CSD) manufactures a standard-size racket and an oversize racket. The ? rm’s rackets are extremely light due to the use of a magnesium-graphite alloy. Each standard-size racket uses 0. 125 kilo grams of the alloy and each oversize racket uses 0. 4 kilograms; over the next two-week production period only 80 kilograms of the alloy are available. Each standard-size racket uses 10 minutes of manufacturing time and each oversize racket uses 12 minutes.Also, 40 hours of manufacturing time are available each week. The pro? t contributions are $10 for each standard-size racket and $15 for each oversize racket. How many rackets of each type should CSD manufacture over the next two weeks to maximize the total pro? t contribution? a. De? ne decision variables and formulate the problem. b. Solve the problem using the graphical method. 1. 3 Management of High Tech Services (HTS) would like to develop a model that will help allocate their technician’s time between service calls to regular contract customers and new customers. Read also Exam Operations ManagementA maximum of 80 hours of technician time is available over the two-week planning period. To satisfy cash ? ow requirements, at least $800 in revenue (per technician) must be generated during the two-week period. Technician time for regular customers generates $25 per hour. However, technician time for new customers only generates an average of $8 per hour. To ensure that new customer contracts are being maintained, the technician time spent on new customer contracts must be at least 60% of the time spent on regular customer contracts. Given these 1 revenue and policy requirements, HTS would like to determine how to allocate echnician time between regular customers and new customers so that the total number of customers contracted during the two-week period will be maximized. Technicians require an average of 50 minutes for each regular customer contract and 1 hour for each new customer contract. a. Develop a linear programming model for the problem . b. Find the optimal solution via Excel. 1. 4 Industrial Designs has been awarded a contract to design a label for a new wine produced by Lake View Winery. The company estimates that 150 hours will be required to complete the project. The ? m’s three graphics designers available for assignment to this project are Lisa, a senior designer and team leader; David, a senior designer; and Sarah, a junior designer. Because Lisa has worked on several projects for Lake View Winery, management speci? ed that Lisa must be assigned at least 40% of the total number of hours assigned to the two senior designers. To provide label-designing experience for Sarah, Sarah must be assigned at least 15% of the total project time. However, the number of hours assigned to Sarah must not exceed 25% of the total number of hours assigned to the two senior designers.Due to other project commitments, Lisa has a maximum of 50 hours available to work on this project. Hourly wage rates are $30 for Lisa, $2 5 for David, and $18 for Sarah. a. Formulate a linear program that can be used to determine the number of hours each graphic designer should be assigned to the project in order to minimize total cost. b. How many hours should each graphic designer be assigned to the project? What is the total cost? c. Suppose Lisa could be assigned more than 50 hours. What e? ect would this have on the optimal solution. Explain. d.If Sarah were not required to work a minimum number of hours on this project, would the optimal solution change? Explain. 1. 5 National Insurance Associated carries an investment portfolio of stocks, bonds, and other investment alternatives.

The contract calls for the production of 3,300 bookshelf speakers and 4,100 ? or speakers over the next two months, with the delivery schedule as given in Table 2. Table 2: Problem 1. 6 Model Month 1 Month 2 Bookshelf 2,100 1,200 Floor 1,500 2,600 Greenville estimates that the production time for each bookshelf model is 0. 7 hour and the production time for each ? oor model is 1 hour. The raw material costs are $10 for each bookshelf model and $12 for each ? oor model. Labor costs are $22 per hour. Greenville has up to 3,400 hours of production time available each month. If production for either cabinet exceeds demand in month 1, the cabinets can be stored at a cost of $5 per cabinet.Formulate the problem to determine the numbers of units 3 that should be manufactured each month to minimize total production and storage costs. 1. 7 EZ-Windows, Inc. manufacturers replacement windows for the home remodeling business. In January, the company produces 15,000 windows and ended the month with 9,000 windows in inventory. EZ-Windows’ management team would like to develop a production schedule for the next three moths. A smooth production schedule is obviously desirable because it maintains the current workforce and provides a similar month-to-month operation.However, given the sales forecasts, the production capacities, and the storage capabilities as shown in Table 3, the management team does not think a smooth p roduction schedule with the same production quantity each month possible. Table 3: Problem 1. 7 February March April Sales forecast 15,000 16,500 20,000 Production capacity 14,000 14,000 18,000 Storage capacity 6,000 6,000 6,000 The company’s cost accounting department estimates that increasing production by one window from one month to the next will increase total costs by $1. 00 for each unit increase in the production level.In addition, decreasing production by one unit from one month to the next will increase total costs by $0. 65 for each unit decrease in the production level. Ignoring production and inventory carrying costs, formulate a linear programming model that will minimize the cost of changing production levels while still satisfying the monthly sales forecasts. 1. 8 Two television stations compete with each other for viewing audience.

Is Fire a Gas, Liquid, or Solid

The ancient Greeks and alchemists thought that fire was itself an element, along with earth, air, and water.  However, the modern definition of an element defines it by the number of protons a pure substance possesses. Fire is made up of many different substances, so it is not an element. For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in the air and a fuel, such as wood or propane. In addition to other products, the reaction produces carbon dioxide, steam, light, and heat. If the flame is hot enough, the gases are ionized and become yet another  state of matter: plasma. Burning a metal, such as magnesium, can ionize the atoms and form plasma. This type of oxidation is the source of the intense light and heat of a plasma torch. While there is a small amount of ionization going on in an ordinary fire, most of the matter in the flame is a gas, so the safest answer for What is the state of matter of fire? is to say its a gas. Or, you can say its mostly gas, with a smaller amount of plasma. Different Composition for Parts of a Flame The structure of a flame varies, depending on which part youre looking at. Near the base of the flame, oxygen, and fuel vapor mix as unburned gas. The composition of this part of the flame depends on the fuel that is being used. Above this is the region where the molecules react with each other in the combustion reaction. Again, the reactants and products depend on the nature of the fuel. Above this region, combustion is complete, and the products of the chemical reaction may be found. Typically this is water vapor and carbon dioxide. If combustion is incomplete, a fire may also give off tiny solid particles of soot or ash. Additional gases may be released from incomplete combustion, especially of dirty fuel, such as carbon monoxide or sulfur dioxide. While its difficult to see it, flames expand outward like other gases. In part, this is hard to observe because we only see the portion of the flame that is hot enough to emit light. A flame isnt round (except in space) because the hot gases are less dense than the surrounding air, so they rise up. The color of the flame is an indication of its temperature and also the chemical composition of the fuel. A flame emits incandescent light, where light with the highest energy (hottest part of the flame) is blue, and that with the least energy (coolest part of the flame) is redder. The chemistry of the fuel plays its part. This is the basis for the flame test to identify chemical composition. For example, a blue flame may appear green if a boron-containing salt is present.
