The objectives of this experiment are to: • define a refrigeration cycle and quantitative measures of its performance. • evaluate the performance of a cycle based on experimental measurements.
Discussion Questions: 1. In the lower levels of the pyramid forecasting system, how would you prevent abdication of the responsibility for forecasting? 2. Can a grocery store capture true demand data? How might a warehouse capture demand data? 3. Some experts have argued it's more important to have low bias (mean error) than to have a low MAD. Why would they argue this way? Problems: 1. Demand for stereo headphones and MP3 players for joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet no safety laws have been passed to prevent joggers from wearing them. Demand for the stereo units for last year was as follows: Demand Month (Units) January 4,200 February 4,300 March 4,000 April 4,400 May 5,000 June 4,700 Demand July August September October Month (Units) 5,300 4,900 5,400 5,700 November 6,300 December 6,000 a. Using least squares regression analysis, what would you estimate demand to be for each month next year? Using a spreadsheet, follow the general format in Figure 3.3. Compare your results to those obtained by using the forecast spreadsheet function. b. To be reasonably confident of meeting demand, Nina decides to use three standard errors of estimate for safety. How many additional units should be held to meet this level of confidence?
A new restaurant would like to investigate if different age groups of customers prefer different types of food items. Each of their customers is given a food item - a burger or a sandwich. Each customer belongs to either adult or child age group. The customers were then surveyed on whether they enjoyed the food item. The table below gives the percentage of customers in each category.
3. Case help (This summarises what you should do for each pricing calculation) Status-quo pricing - Current pricing practice. Traditional pricing suggested by Matzer Competitor pricing - Use competitor price as a reference. Match competitor (Ontario Zink) price. Cost-plus pricing - Consider variable cost and fixed costs per unit (total fixed cost divided by expected unit sales). In this case, there is useful information to be used. Unit sales for the basic segment (and its projection). Atlantic's share of the basic segment will give the total unit sales figure for Atlantic. Note that only 50% of units will have PESA. No variable costs involved (simple installation) Total Fixed cost: R&D cost. Markup (%) = 30% Combining the above information, you should be able to compute how much the bundle should cost. Value-in-use pricing - Compute savings, i.e., economic value, achieved by purchasing Atlantic Tronn + PESA instead of Ontario Zink. Less number of servers (2 Tronn servers versus 4 Ontario Zink) Less labour for each server (each labour can manage 40 servers) Less electricity Less additional software application licenses. Total savings are equal to the maximum value of PESA 50-50 value sharing between Atlantic and customers. So, the final pricing of PESA equals 50% of the maximum economic value of PESA. This is the additional value- added to hardware. Answer the following questions What price should Jowers charge DayTraderJournal.com for the Atlantic Bundle (i.e., Tronn servers+PESA software tool)? Think broadly about the top-line revenue implications from each of the four alternative pricing strategies. Approximately how much money over the next three years will be "left on the table" if the firm were to give away the software tool for free (i.e., status quo pricing) versus utilizing one of the other pricing approaches? How is Matzer likely to react to your recommendations? How is Cadena's sales force likely to react to your recommendation? What can Jowers recommend to get Cadena's hardware-oriented sales force to understand and sell the value of the PESA software effectively? How are customers in the firm's target market likely to react to your recommended pricing strategy? What response can be provided to overcome any objections?/n1. Atlantic Computer: A Bundle of Pricing Options 2078-PDF-ENG https://hbsp.harvard.edu/tu/621b1cbe Atlantic Computer: A Bundle of Pricing Options, Student Spreadsheet 920567-XLS- ENG https://hbsp.harvard.edu/tu/028cffd5 Exhibit 3 of this spreadsheet has Tronn server's cost as $1,358, but you should use $1,538 presented in the case. 2. Case discussion questions (Answer these in your case write-up report) The purpose of the Atlantic Computer case is to introduce students to the following commonly used approaches to determining price: (a) status-quo pricing, (b) comparative framing (or competition-based) pricing, (c) cost-plus pricing, and (d) value-based pricing. You are also asked to consider the reactions of competitors, customers, and internal stakeholders (e.g., salespeople) to different pricing approaches. After working on this case, you should have a firm grasp of basic pricing approaches and an appreciation for the many moving parts to be considered when setting price for a new product.

1. Consider an auto wash shop with 2 machines. There are 6 spaces available for the cars to wait. Any car that arrives and finds the shop full, leaves the shop. The arrival rate is exponential with a rate of 2 cars per hour. The service time of a repairman is normally distributed with a mean of 10 minutes and a standard deviation of 2 minutes. The number of waiting spaces can be changed by the management. Identify range of the following variables and the parameters for this system: .State variables . Decision variables .System parameters
1. Circuit 1: Find the output voltage Vo, output current lo,and closed loop gain G = 4 for the op-amp circuit below, assuming the op-amp is ideal. Show all your work, use only KCL and the ideal assumptions to find the output voltage. Let Vs = 1V, R1 = 80K, R2 =20K and RL = 1K. Power supply voltages are +Vcc = 15V and -Vcc = -15V. Hint: To find l,first find Vo, and then perform KCL at V, to find the current in each branch at that node.
Consider the design project on which you are currently working as the basis for the following instructions and questions. 1. List a specific technical topic about which you have needed more knowledge than what you have gained in the classroom. 2. List and discuss the specific ways (sources, techniques, etc.) that you have gained this knowledge. ("The internet", any online search engine, Wikipedia, and other similar sources do not qualify as valid sources/methods/techniques and will void your answer to this question). 3. Discuss other methods or techniques that you think would be helpful in learning the fundamentals of a new technology. ("The internet", any online search engine, Wikipedia, and other similar sources do not qualify as valid sources/ methods/ techniques and will void your answer to this question). 4. List any specific conferences where you believe you would gain more knowledge and insight into the issues you are facing in your design project. One suggested source for finding these conferences is the IEEE website or other professional societies. 5. Find on the IEEE Learning Network (https://iln.ieee.org/public/TrainingCatalog.aspx) a technical topic that you would like to learn (more) about. In a sentence or two, summarize the abstract of the lecture/course. Then explain why this is of interest to you or relevant to your project.
