...Decision Trees The Decision Tree module in Excel OM (and in POM for Windows) acts differently than all other modules because rather than creating a table of data it creates a graphical tree. We will use Example 3 in Chapter A5 from Heizer & Render’s Operations Management textbook for our example. After selecting the Decision Tree Module the screen will appear as in Figure 1 below. Figure 1: The Initial Decision Tree Screen Notice the Decision Tree Creation Window on the right. This is used to perform all of the work of constructing the tree. The initial screen has 1 starting node (Node 1) which can be seen in cell A6. The first step is to add branches from this node. The default setting is to Add 2 Decision branches. The type of branch is selected by the choice of “Add” buttons that is selected and the number of branches is selected by the textbox/scrollbar combination. For this example, there are three options – Purchase CAD, Hire Engineers or Do Nothing. Therefore we will change the number of branches to 3 and click on the “Add Decisions” button. This yields the screen as displayed in Figure 2. Decision Trees.doc Page 1 of 7 Figure 2: The First Three Branches At this point the data can be entered into the shaded green cells. For decision branches, the data consists of the name of the branch and possibly a profit or cost. If the branch is at the end of the tree then the profit gets entered. If the branch is not at the end then any intermediate profits or costs...

...HKU552 XIANGHUA LU DAQIING ZHENG E-BUSINESS TRANSFORMATION AT ME-ONLINE The development of Shanghai Me Mechanical and Electrical Equipment Chain Co. Ltd. (SHMEC), a traditional mechanical and electrical equipment distribution company, mirrored the agony and frustration experienced by many other small and medium-sized enterprises operating during China’s socio-economic transformation process, particularly as it faced the challenge brought by information technology. The company’s growth parallels a Chinese fairy tale “Fenghuang nie pan”, the story of a phoenix that, dissatisfied with its beauty, consumes itself by fire, but rises from the ashes with surpassing beauty. Capitalising on opportunities offered by the internet, the company established Me-online as a trading platform, using e-business to transform its business model. Me-online exemplifies a traditional company in China that effected strategic changes through e-business, offering insights into the opportunities and challenges encountered. Background The Industry The mechanical and electrical equipment distribution industry in China represents a huge sector, characterised by numerous types of products and low costs of entry. From 1949 to 1990, when China was a planned economy, this seller-driven market was mainly run by stateowned enterprises. Therefore, little attention was paid to the marketing or selling of products. The common perception was that if SHMEC established chain stores on the Huangpu River, customers...

...Decision Trees Using TreePlan 16 16.1 TREEPLAN OVERVIEW TreePlan is a decision tree add-in for Microsoft Excel 97–2007 for Windows and Macintosh. TreePlan helps you build a decision tree diagram in an Excel worksheet using dialog boxes. Decision trees are useful for analyzing sequential decision problems under uncertainty. Your decision tree model may include various controllable alternatives (e.g., whether to introduce a new product, whether to bid on a new project) and uncontrollable uncertainties (e.g., possible demand for a product, whether you're awarded a contract), arranged in chronological order. TreePlan automatically includes formulas for summing cash flows to obtain outcome values and for calculating rollback values for determining the optimal strategy. To use TreePlan, you (1) open a new worksheet, (2) choose Tools | Decision Tree from Excel's menu, (3) select a node to change the structure of your decision tree, (4) enter branch names, cash flows, and probabilities, and (5) determine the optimal strategy from TreePlan's results. All of TreePlan’s functionality, including its built-in help, is a part of the TreePlan XLA file. There is no separate setup file or help file. When you use TreePlan on a Windows computer, it does not create any Windows Registry entries (although Excel may use such entries to keep track of its add-ins). 16.2 BUILDING A DECISION TREE IN TREEPLAN You can start TreePlan either by choosing Tools | Decision Tree from the menu bar (Excel...

...Decision Tree Gerber Product Company A. Background of the Company: Gerber was founded in 1927 in Fremont, Michigan by Daniel Frank Gerber, owner of the Fremont Canning Company, which produced canned fruit and vegetables. At the suggestion of a pediatrician, Gerber's wife Dorothy Gerber began making hand-strained food for their seven-month-old daughter, Sally. Recognising a business opportunity, Gerber began making baby food. By 1928 he had developed five products for the market and six months later, Gerber's baby foods were distributed nationwide. The brand eventually became a major company in the baby food industry, offering more than 190 products in 80 countries, with labeling in 16 languages and controls eighty-three percent (83%) of the baby food market in the United States. In 1994 Gerber merged with Sandoz Laboratories. Two years later, Sandoz merged with CIBA-Geigy to form Novartis, one of the largest pharmaceutical companies in the world. In 2007 Gerber was sold to Nestle for $5.5 billion. In 1960 Gerber started selling its baby food in glass jars, which often found new life as household storage, especially in home workshops. Soon after, other items such as pacifiers, , baby bottles, and small baby toys were introduced. Source: https://en.wikipedia.org/wiki/Gerber_Products_Company B.

We showed the decision analysis by using both the FCF and the net cash flow. We have used three options such as a. Timing option, b. Decision Tree Analysis, and c. Option to Wait (Black Scholes Model). |1. Timing Option | We have used Timing Option to calculate the NPV if the stocks were issued immediately. Here we consider FCF in the three methods. Here, we assume 30% probability for high demand, 40% for average and 30% for low demand. We calculated the net annual cash flow for each scenario and then calculated the expected NPV for the issuance. |Demand |Probability |Annual FCF |E(NPV) | |High |30% |142400.97 |686590.51 | |Average |40% |109539.20 |526734.24 | |Low |30% |76677.44 |366877.96 | If Spiegel issued the stocks immediately the Expected net present value gained by the company would be $526734.24 thousand. |2.

...MGMT 530 Week 5 Case Analysis Labadee Decision To Buy This material Click below link http://www.uoptutors.com/mgmt-530/mgmt-530-week-5-case-analysis-labadee-decision In January 2010, the island nation of Haiti was devastated by an earthquake. Royal Caribbean International, a major cruise line, owns a private beach in Haiti, which is typically a port of call on several of their Caribbean cruise itineraries. The private port, known as Labadee, is about 80 miles away from Port au Prince. The beach was unaffected by the quake. In the days following the earthquake, the company wrestled with several issues as they determined whether to continue to stop in Labadee or temporarily abandon the port of call. Their objectives would be to 1) ensure guest satisfaction; 2) protect the brand; and 3) maximize profitability. Some of the consequences they considered as they tried to determine whether the cruise line should continue to make a stop in Haiti in the midst of this crisis are as follows. Will cruise passengers be interested in relaxing on a beach when hundreds of thousands are homeless and hungry just 80 miles away? Could this impact new reservations or cause people to cancel? Based on research and consulting with others, you believe there will be minimal impact. Because the community near the beach depends financially on the cruise line for income, would suspending the stop in Haiti make the country worse off? Based on your analysis, there is a high likelihood that the area...

...on Student Academic Performances investigating the effect of students socio-economic/family background on students academic performance in tertiary institutions using decision tree algorithms A. B. Adeyemo (Ph.D)1 and S. O. Kuyoro (M.Sc.)2 Department of Computer Science, University of Ibadan, Ibadan, Nigeria Abstract The causes of the difference in the academic performance of students in tertiary institutions has for a long time been the focus of study among higher education managers, parents, government and researchers. The cause of this differential can be due to intellective, non-intellective factors or both. From studies investigating student performance and related problems it has been determined that academic success is dependent on many factors such as; grades and achievements, personality and expectations, and academic environments. This work uses data mining techniques to investigate the effect of socio-economic or family background on the performance of students using the data from one of the Nigerian tertiary institutions as case study. The analysis was carried out using Decision Tree algorithms. The data comprised of two hundred forty (240) records of students. The academic performance of students was measured by the students’ first year cumulative grade point average (CGPA). Various Decision Tree algorithms were investigated and the algorithm which best models the data was used to generate rule sets which can be used to analyze the effect of the socio-economic background...

...Case Problem #2 Steeley Associates, Inc. a property development firm, property development firm purchased an old house near the town square in Concord Falls, where State University is located. The old house was built in the mid-1800s, and Steeley Associates restored it. For almost a decade, Steeley has leased it to the university for academic office space. The house is located on a wide lawn and has become a town landmark. However, in 2003, the lease with the university expired, and Steeley Associates decided to build high-density student apartments on the site, using all the open space. The community was outraged and objected to the town council. The legal counsel for the town spoke with a representative from Steeley and hinted that if Steeley requested a permit, the town would probably reject it. Steeley had reviewed the town building code and felt confident that its plan was within the guidelines, but that did not necessarily mean that it could win a lawsuit against the town to force the town to grant a permit. The principals of Steeley Associates held a series of meetings to review their alternatives. They decided that they had three options: they would request the permit, they could sell the property, or they could request a permit for a low-density office building, which the town had indicated it would not fight. Regarding the last two options, if they sell the house and property, they think they can get $900,000. If they build a new office building, their...
