...Chapter 1 Operations and Productivity 1. What is operations management? a. Production is the creation of goods and services. b. Operations Management (OM): Activities that relate to the creation of goods and services through the transformation of inputs to outputs. (For both tangible and intangible activities in an organization) 2. Organizing to Produce Goods and Services c. All organizations must perform three functions: i. Marketing: generates the demand, or at least takes the order for a product or service (nothing happens until there is a sale) ii. Production/operations: creates the product. iii. Finance/accounting: tracks how well the organization is doing, pays the bills, and collects money. 3. Why study OM? d. OM is one of the three major functions of any organization, and it is integrally related to all the other business functions. All organizations market, finance, and produce, and it is important to know how the OM activity functions. Therefore, we study how people organize themselves for productive enterprise. e. We study OM because we want to know how goods and services are produced. The production function is the segment of our society that creates the products and services we use. f. We study OM to understand what operations managers do. g. We study OM because it is such a closely part of an organization. A large percentage of the revenue of most firms is spent in the OM...

...Members: Anthony Combes Jerick Angeles Industry: Telecommunications I. Introduction Telecommunications is a universal term that is used for a vast range of information-transmitting technologies such as mobile phones, land lines, VoIP and broadcast networks. It is one of the fastest-growing industries in the world, especially in the developing countries. It is a process where in an exchange of information occurs by means of electronic and electrical over a distance. An example of a complete arrangement of this process is that, it is made up of two or more stations provided each with transmitter and receiver devices. There is this so called transceiver, a single co-arrangement of transmitters and receivers that may also be used by telecommunication stations. In telecommunications, information is passed through forms of electrical signals which are the carrier waves that are modulated into analog or digital signals for transmitting information. Telecommunication all began in Africa, some parts of Asia and the Americas with the use of smoke signals and drums. Until, in the year 1830’s, electrical telecommunication systems started to appear already. With the advancement of the technology today, no doubt why time and distance as obstacles to communication is not is not problem anymore. Telecommunication has been always beneficial to many parts of the society such as businesses, international relationships and many more. http://www.ehow.com/about_6130768_technology-improved-communication...

Constructing Formulas for Mathematical Operations in Excel (Basic Tips and Techniques)

...Constructing Formulas for Mathematical Operations in Excel (Basic Tips and Techniques) Michelle A. Applequist Computer Information Systems (CIS105) Professor Hari Dhungana Strayer University September 1, 2009 Constructing Formulas for Mathematical Operations in Excel Microsoft Excel uses formulas to construct mathematical operations in a worksheet. After data have been entered into the worksheet, you can perform calculations, analyze data, and create charts. An Excel formula (calculations you create) and functions (formulas pre-existing in Excel) calculates the data entered in the worksheet. Formulas calculate numbers in a particular order. “Excel has one of the most comprehensive set of formulas, not only to perform calculations but also to manage data and records. It also has the ability to instantaneously re-calculate the results as the raw data changes” (Khoo, 2006-9, para. 2). To construct a formula after you have entered data, you must click in the cell that you want the results to appear in, and then type the formula. You can construct formulas by using the sum function, and editing numbers in a cell. It is stated that: Sum is an Excel function—a prewritten formula. Sum indicates the type of calculation that will take place (addition). When the sum function is activated, Excel looks above the active cell for a range of cells to sum. If there is no range above the cell, Excel will look to the left for a range of cells to...

My learning strategy stayed the same from last week; read the reading material, look at the optional video lectures, answer the discussion question, program the programming assignment, take the self-quiz, etc. … I appreciate learning about the for … each loop. I’m plenty familiar with the for loop, which iterates for a set number of loops, uses initialization, a continue condition, and updating at the top of its block; but, the for … each control structure is a alternative to for. The for .. each loop control structure does not have as complicated continue conditions, and iterates the length of the data structure.

In its first month of operation, Maze Company purchased 100 units of inventory for $6, then 200 units for $7, and finally 150 units for $8. At the end of the month, 180 units remained. Compute the amount of phantom profit that would result if the company used FIFO rather than LIFO. The company uses the periodic method. FIFO: $1,410 150 units multiplied by $8 equals $1,200 30 units multiplied by $7 equals $210 $1,200 plus $210 equals $1,410 LIFO: $1,160 100 units multiplied by $6 equals $600 80 units multiplied by $7 equals $560 $600 plus $560 equals to $1,160 Therefore, the phantom profit would be $250 if the company were to use the FIFO rather than LIFO.

...Operations Management and Ethical Issue According to Aquilano, Chase, and Jacobs (2005), "Operations management (OM) is defined as the design, operation, and improvement of the systems that create and deliver the firm's primary products and services" (p.19). Operations management is a dynamic field and presents exciting new issues and challenges for operations managers. For example, Maura Sprenger, human resources director at Techno Inc., a fast growing information technology company, is faced with a very difficult issue between winning a multimillion dollar business contract with Apex Company or run the risk of causing a very knowledgeable and valuable employee to quit. Sprenger faces a dilemma on ethical issues related to diversity in the workplace. And the risk of losing a deal with Apex company, a large client. In addition, Techno presents a false expectation to Apex Company to close a deal which would run the rise of losing the contract deal. Jack Ridge, Techno's vice president for sales and marketing departmenttries to sell a major contract to Apex and with a visit to was Apex's headquarter Ridge is impressed with Apex's diversity program. Ridge is under the impression that executives at Apex are very proactive about the diversity of its workforce and likes its vendors to reflect the same commitment. Techno has its own employee diversity committee, staff training, and recruiting efforts, however, the staff's diversity is very limited. Because Ridge does not want to send...

Fixed costs and potential volumes are as follows: Number Total Annual Corresponding of machines Fixed Costs Range of Output 1 $ 9 600 0 to 300 2 $ 15 000 301 to 600 3 $ 20 000 601 to 900 Variable cost is $10 per unit, and revenue is $40 per unit. Help the manager determine break-even point for each range. If projected annual demand is between 580 and 660 units, how many machines should the manager purchase? Problem 2 A company is preparing to introduce a new product. Demand is uncertain. According to a market research conducted on behalf of the company, it is estimated that the demand can be High (H) with a probability 70% percent and Low (L) with a probability 30%. After the first 2 years if the initial demand is high, there is 15% likelihood that it will drop to Low and 85% likelihood that it will remain High. If, on the other hand, the initial demand is Low, it will remain Low with no chance to of increasing to High. The company has to select among 2 alternatives. A) start dynamically making a new big investment worth of 300000$ B) Start conservatively using existing equipment and technology and making a small investment of 100000$. In this case, and if the demand is high, the company may after 2 years make an additional investment to expand...
