# Case problem 2 forcasting lost sales

It is vogue today to diminish the value of mathematical extrapolation. These closing costs, he has found, include a 1 percent origination fee, 2 discount points on the mortgage, and 3 percent of the home cost in other various fees due at closing.

Finally, it presents a well constructed conclusion elaborating on the relevance of the solutions obtained. One of the exercises we did was a Delphi Method to predict developments that would have significant impact on Air Force Transportation programs. Here is a screen shot of a game I am currently playing, showing the results of Andrews sales in round 2.

The author describes the evolution of fuzzy logic since its introduction in The advantage of the model is that it forces planners to take a long-term look at the future. Regression models rely on historical information about both predictor variables and the response variable of interest.

The author discusses judgmental forecasting as an important component for business forecasting. It may be that past is a reflection of our current conceptual reference. Nearly everyone would agree that we have the right to create our own future.

Judgmental forecasting usually involves combining forecasts from more than one source. For the best case cell formula, I used Worst Case number x 1. A forecast of sales for January through December of the fourth year.

The purpose of forecasting is to control the present. In the social sciences however, their accuracy is somewhat diminished. It provides more accurate forecasts than group discussions.

Forecasting may be a method of creating illusions. Lack of coordinated decision-making by all functions in the firm may lead to excess inventories. Other factors, such as risk, are also considered. It should also be noted that since companies use computer software time series forecasting packages rather than hand computations, they may try several different techniques and select the technique which has the best measure of accuracy lowest error.

The store was closed for four months September through Decemberand Carlson is now involved in a dispute with its insurance company concerning the amount of lost sales during the time the store was closed.

Most students expressed strong reservations against extreme technological changes. Do Forecasts Create the Future A paradox exists in preparing a forecast. An estimate of countywide department store sales had there been no hurricane. Many futurists de Jouvenel, Dublin, Pohl, and others have expressed the idea that the way we contemplate the future is an expression of our desire to create that future.

Carlson is entitled to compensation for excess sales it would have earned in addition to ordinary sales. In the final round, participants are asked to reassess their original opinion in view of those presented by other participants.

The study of the historical data is called exploratory data analysis. The anonymous forecasts may be gathered through a Web Site, via e-mail or by questionnaire.

Historical data is available for 12 quarters, or three years. Clarke reminds us of a potential danger in our reliance on mathematical models.

It is a "script" for defining the particulars of an uncertain future. The author discusses what we have learned by examining computer models of chaos. Quantitative models are designed to address the various components covered above.

There is always room for judgmental adjustments to our quantitative forecasts. Even the most mathematically rigorous techniques involve judgmental inputs that can dramatically alter the forecast.

We predict the future based on knowledge, intuition and logic. The second principle is really important. It is doubtful that forecasters can leave their own personal biases out of the forecasting process. Involved forecasting seeks the opinions of all those directly affected by the forecast e.

Rather than lock in elaborate sales and supply plans based on a point forecast that is likely to be wrong, the organization can use the structured analogy process to.

1 s Forecasting with moving averages Robert Nau Fuqua School of Business, Duke University The RW model is the special case in which m=1. The SMA model has the following characteristic properties: Hence, the “average age” of the data in the forecast is (m+1)/2. Forecasting “Prediction is very difficult, especially if it's about the future.” Nils Bohr Objectives Give the fundamental rules of forecasting Calculate a forecast using a moving average, weighted moving average, and exponential smoothing Calculate the accuracy of a forecast What’s Forecasting All About?

88 CHAPTER 3 COST-VOLUME-PROFIT ANALYSIS Key Decision Factors for Coleco What went wrong with Coleco’s decision to emphasize production of Adam instead of Cab- bage Patch Dolls?

The problems began with uncertainties about which products would be popular at Christmas. Coleco’s managers could not know which products would sell best.

WORST/BEST CASE FORECASTING TECHNIQUE Of the 3 forecasting methods I have tried in Capsim, I think the best (and easiest) is the Worst/Best Case method. The good news is that both production numbers are above my worst case forecast, so all is not lost.

Remember to buy capacity in the round BEFORE you need it. where I offer more sales. The forecast gives the planner a guide to future demand, but no forecast is totally accurate and the planners experience and knowledge of the current and future environment is important in determining the future demand for a company’s products.
