The findings yield conclusions that differ substantially from current practice. For problems where there are insufficient data, where one must rely on judgment. The key with judgment is to impose structure with methods such as surveys of intentions or expectations, judgmental bootstrapping, structured analogies, and simulated interaction. Avoid methods that lack evidence on efficacy such as intuition, unstructured meetings, and focus groups. Given ample data, use quantitative methods including extrapolation, quantitative analogies, rule-based forecasting, and causal methods. Among causal methods, econometric methods are useful given good theory, and few key...

...The Importance of Accurate Demand Forecasting An Analysis of VMU America Inc. Christopher Chun & William McMahan Oakland University Abstract Most strategic business decisions, such as financial planning and production management, rely heavily on forecasts that attempt to paint an accurate picture of the future periods. Ineffective forecasting can lead businesses to improper conclusions about the environment in which they operate. The purpose of this research is to analyze the effectiveness of VMU Power Systems’ forecasting methods on production demand. Once the type/s of forecasting used is identified, a closer look highlights the fact that improvements to their methods could put the company in a better position to handle their current market demand. The underlying issue is that they are not including all of their products & services in their data set, or more simply put, they are basing their decisions off of incomplete data. This is causing their forecasted results to be far below the actual demand resulting in a lack of resources to produce at the levels required. Other research has been cited throughout this paper to further support the claims that it is possible for VMU to forecast their type of intermittent demand. There are two main recommendations made at the end of this analysis that, if implemented, could improve the accuracy of their models. The first suggestion is to use the SBA forecasting method on their after-sales demand. The second recommendation...

...DEMAND FORECASTING - REPORT Forecasted Method Used: In present forecasting method, the “Executive opinion” is used to determine the forecast of sales and results are not validated by any mathematical/statistical method. * Pressure Valves: 1. The total sales forecasted were optimistic at 53560 against the actual sales of 48159. 2. The Mean Absolute Percentage Error(MAPE) value of total sales of the entire family of pressure valves is around 11.2%, which is reasonably acceptable but the MAPE valves for individual members are very high (reaching up to 1500% for PVB34-420). * Fire Valves: 1. The total sales forecasted were pessimistic at 559 against the actual sales of 580. 2. The Mean Absolute Percentage Error (MAPE) value of total sales of the entire family of fire valves is around -3.5% (negative sign represents pessimistic forecast), which is reasonably acceptable but, MAPE for the individual family member Z3000il is -52.88, which is very high. * Effects: It may be severely affect the company’s profit :- 1. Over forecasting (optimistic forecasting) may result in more units of product lying in warehouse which blocks the capital as well as there will be space constraints to keep the stocks. 2. Under forecasting (pessimistic forecasting) may result in loss of market share and the customers and thus, leading the bad goodwill to the company. Our Forecast Method: We have used Regression analysis to forecast the sales. We analysed...

...Broadly speaking, there are two approaches to demand forecasting. Survey method and Statistical method are further sub-divided into various methods. The former obtains information about the consumers’ intentions by conducting consumers’ interviews, through collecting experts’ opinions. The later using past experience as a guide and by extrapolating past statistical- relationships suggests the level of future demand. Survey methods are found appropriate for short term forecasting or demand estimation, while statistical methods are more suitable for long term demand forecasting or business and economic forecasting. Either of the methods may be used for forecasting demand for existing products, but the demand for new products, in the absence of any historical data, must be forecast through the survey method only. Under survey methods surveys are conducted about the consumers’ intentions, opinions of experts, survey of managerial plans, or of markets. Data obtained through these methods are analyzed, and forecasts on demand are made. These methods are generally used to make short-run forecast of demand. Survey methods are further sub-divided in to: Consumers’ Survey and Experts’ Opinion and Survey of Managerial Plans. A. Consumers’ Survey: Consumers’ survey involves direct interview of the potential consumers who are contacted by the interviewer and asked how much they would be willing to buy a given product at different prices. Consumers’ survey may take any form...

...Benny Breweries: Bottle Replenishment THE BOTTLE REPLENISHMENT DECISION Early in 2014, Manish Krishnan, purchasing manager for Benny Breweries, Mangalore, was trying to determine how many bottles to purchase in the coming year. During 2013, the market had leveled off, and 2014 sales predictions were difficult. On the one hand, Krishnan wanted to be sure that sufficient bottles were available to supply 2014 sales levels, yet also wanted to minimize year-end inventories. Covered storage space for empty bottles was tight, and a bottle design change seemed possible in 2015 or 2016. COMPANY BACKGROUND Benny Breweries was located in Mangalore. Over the years, the company had established an excellent reputation. Benny Beer had begun to gain popularity of late, and as a result, a modest market expansion started in 2010. In February 2014, sales reached the highest level in the company’s history. However, in 2013, the sales increase had been well below the trend average (see Exhibits 1 and 2). Four sales peaks occurred during the year: Holi, Christmas, Easter and Onam (refer appended note). Holi was the highest sales period but each peak caused the company to operate on tight schedules and Benny hired more labor and scheduled extra shifts. BREWING PROCESS Beer brewing started with extraction of sugar from malt by an enzymic process. This sugar was then boiled with hops, producing a sterilized and concentrated solution. The resins extracted from the hops during boiling acted as a preservative...

...Abstract Five different forecasting models were used to examine a logo branded coffeemaker that is sold by Starbucks. A simple moving average was used for the first two models using 5 weeks past (figure 1) data and 3 weeks past data (Figure 2. The next method used was a exponential smoothing method with .4 alpha and 5 weeks data (Figure 3) and .2 alpha with 3 weeks data (Figure 4). The mean absolute deviation, mean absolute percent error and tracking signal were calculated based off of the total of all segments. Simple Moving Average Looking at Figure 1 and Figure 2 where a moving average forecast was used, the 3 and 5 week data were very similar in the mean absolute deviation, and percent error. The tracking signal is where they were the most different. Since the cumulative deviation (RSFE) was negative, the tracking number for the three week data was negative which show that forecasts are too high. If you look at the -4 data column, you can see that this number is significantly lower than the rest of the prior week’s numbers. This dip in sales is what caused the forecasts for the 3 week data to be higher while the forecasts for the 5 week data were lower causing a positive RSFE and therefore a positive tracking signal. Exponential Smoothing Figures 3 and 4 used the exponential smoothing forecast method. Comparing with the moving average, the 3 week data with the alpha of .2 most signifies the data that was recorded in Figures 1 and 2. The rule of thumb when switching...

...Running Head: DEMAND AND FORECASTING Making Decisions Based on Demand and Forecasting [bami] strayer University] Making Decisions Based on Demand and Forecasting The demographics used for the demand analysis are the average yearly income of the house hold in Georgia, the total yearly population, and average kids per house. The rationale behind choosing these demographics is that the demand is highly associated with the average income, and can have a great impact on the demand of the economy, for higher the income, the higher the spending ability of an average house hold. Therefore, it can also be said that the average income is directly proportional to the spending ability of an average house hold, whereas as far as total yearly population is concerned, demand is also associated with the total population, as for demand arises with rise in population. Average kids per house hold also have a strong link with demand. Considering the fact that pizza is highly popular among kids, and is the cause of its major demand. The other independent variables used for conducting a demand analysis are price of the pizza, and price of the soda. The rationale behind choosing these demographics is that the demand is also highly associated with price, as per the demand and supply law, the lower the price the higher the demand, and the higher the price, the lower the demand. Pizza and soda are two main products of a pizza restaurant...
