Yes No 19DELPHI METHOD: DELPHI METHOD Main advantages Generate consensus Can forecast long-term trend without availability of historical data Main drawbacks Slow process Experts are not accountable for their responses Little evidence that reliable long-term forecasts can be generated with Delphi or other methods 20DELPHI METHOD: DELPHI METHOD Typical application Long-term forecasting Technology forecasting 21TIME SERIES PROJECTION METHODS: TIME SERIES PROJECTION METHODS These methods generate forecasts on the basis of an analysis of the historical time series. Assume that what has occurred in the past will continue to occur in the future Relate the forecast to only one factor - time The important time series projection methods are: Trend Projection Method Exponential Smoothing Method Moving Average Method 22Linear Trend Line: Linear Trend Line 12- 23 y = a + bx where a = intercept of the relationship b = slope of the line x = time period y = forecast for demand for period x b = a = y - b x where n = number of periods x = = mean of the x values y = = mean of the y values xy - nxy x 2 - nx 2 x n y n 23Least Squares Example: Least Squares Example 12- 24 x (PERIOD) y (DEMAND) xy x 2 1 73 73 1 2 40 80 4 3 41 123 9 4 37 148 16 5 45 225 25 6 50 300 36 7 43 301 49 8 47 376 64 9 56 504 81 10 52 520 100 11 55 605 121 12 54 648 144 78 557 3867 650 24Least Squares Example (cont.): Least Squares Example (cont.) 12- 25 x = = 6.5 y = = 46.42 b = = =1.72 a = y -

) F t where: F t +1 = forecast for next period D t = actual demand for present period F t = previously determined forecast for present period = weighting factor, smoothing constant 29Effect of Smoothing Constant: Effect of Smoothing Constant 12- 30 0.0 1.0 If = 0.20, then F t +1 = 0.20 D t + 0.80 F t If = 0, then F t +1 = 0 D t + 1 F t = F t Forecast does not reflect recent data If = 1, then F t +1 = 1 D t + 0 F t = D t Forecast based only on most recent data 30Exponential Smoothing (α=0.30): Exponential Smoothing ( α =0.30) 12- 31 F 2 = D 1 + (1 - ) F 1 = (0.30)(37) + (0.70)(37) = 37 F 3 = D 2 + (1 - ) F 2 = (0.30)(40) + (0.70)(37) = 37.9 F 13 = D 12 + (1 - ) F 12 = (0.30)(54) + (0.70)(50.84) = 51.79 PERIOD MONTH DEMAND 1 Jan 37 2 Feb 40 3 Mar 41 4 Apr 37 5 May 45 6 Jun 50 7 Jul 43 8 Aug 47 9 Sep 56 10 Oct 52 11 Nov 55 12 Dec 54 31Exponential Smoothing (cont.): Exponential Smoothing (cont.) 12- 32 FORECAST, F t + 1 PERIOD MONTH DEMAND ( = 0.3) ( = 0.5) 1 Jan 37 – – 2 Feb 40 37.00 37.00 3 Mar 41 37.90 38.50 4 Apr 37 38.83 39.75 5 May 45 38.28 38.37 6 Jun 50 40.29 41.68 7 Jul 43 43.20 45.84 8 Aug 47 43.14 44.42 9 Sep 56 44.30 45.71 10 Oct 52 47.81 50.85 11 Nov 55 49.06 51.42 12 Dec 54 50.84 53.21 13 Jan – 51.79 53.61 32Exponential Smoothing (cont.): Exponential Smoothing (cont.) 12- 33 70 – 60 – 50 – 40 – 30 – 20 – 10 – 0 – | | | | | | | | | | | | | 1 2 3 4 5 6 7 8 9 10 11 12 13 Actual Orders Month = 0.50 = 0.30 33Moving Average: Moving Average Naive forecast demand in current period is used as next period’s forecast Simple moving average uses average demand for a fixed sequence of periods stable demand with no pronounced behavioral patterns Weighted moving average weights are assigned to most recent data 12- 34 34Moving Average: Naïve Approach: Moving Average: Naïve Approach 12- 35 Jan 120 Feb 90 Mar 100 Apr 75 May 110 June 50 July 75 Aug 130 Sept 110 Oct 90 ORDERS MONTH PER MONTH -

Chain Ratio Method Consumption Level Method End Use Method Leading Indicator Method Econometric Method 42CHAIN RATIO METHOD: CHAIN RATIO METHOD Market Potential for heated coats in the U.S.: Population (U) = 280,000,000 Proportion of U that are age over 16 (A) = 75% Proportion of A that are men (M) = 50% Proportion of M that have incomes over $65k (I) = 50% Proportion of I that live in cold states (C) = 50% Proportion of C that ski regularly (S) = 10% Proportion of S that are fashion conscious (F) = 30% Proportion of F that are early adopters (E) = 10% Average number of ski coats purchased per year (Y) = .5 coats Average price per coat (P) = $ 200 43CHAIN RATIO METHOD: CHAIN RATIO METHOD Market Potential for heated coats in the U.S.: Market Sales Potential = U x A x M x I x C x S x F x E x Y = 280 Million x 0.75 x 0.50 x 0.50 x 0.50 x 0.10 x 0.30 x 0.10 x200 = $7.88 Million 44CONSUMPTION LEVEL METHOD: CONSUMPTION LEVEL METHOD This method is used for those products that are directly consumed. This method measures the consumption level on the basis of elasticity coefficients. The important ones are 45CONSUMPTION LEVEL METHOD: CONSUMPTION LEVEL METHOD Income Elasticity: This reflects the responsiveness of demand to variations in income. It is calculated as: E1 = [Q2 - Q1/ I2- I1] * [I1+I2/ Q2 +Q1] Where E1 = Income elasticity of demand Q1 = quantity demanded in the base year Q2 = quantity demanded in the following year I1 = income level in the base year I2 = income level in the following year 46CONSUMPTION LEVEL METHOD: CONSUMPTION LEVEL METHOD Price Elasticity: This reflects the responsiveness of demand to variations in price. It is calculated as: EP = [Q2 - Q1/ P2- P1] * [P1+P2/ Q2 +Q1] Where EP = Price elasticity of demand Q1 = quantity demanded in the base year Q2 = quantity demanded in the following year P1 = price level in the base year P2 = price level in the following year 47END USE METHOD: Suitable for estimating demand for intermediate products Also called as consumption coefficient method Steps Identify the possible uses of the products Define the consumption coefficient of the product for various uses Project the output levels for the consuming industries Derive the demand for the project END USE METHOD 48END USE METHOD: END USE METHOD This method forecasts the demand based on the consumption coefficient of the various uses of the product. Projected Demand for Indchem Consumption Coefficient Projected Output in Year X Projected Demand for Indchem in Year X Alpha Beta Kappa Gamma 2.0 1.2 0.8 0.5 10,000 15,000 20,000 30,000 Total 20,000 18,000 16,000 15,000 69,000 49LEADING INDICATOR METHOD: LEADING INDICATOR METHOD This method uses the changes in the leading indicators to predict the changes in the lagging indicators. Two basic steps: Identify the appropriate leading indicator(s) Establish the relationship between the leading indicator(s) and the variable to forecast. 50ECONOMETRIC METHOD: ECONOMETRIC METHOD An advanced forecasting tool, it is a mathematical expression of economic relationships derived from economic theory. Economic variables incorporated in the model 1. Single Equation Model D t = a 0 + a 1 P t + a 2 N t Where D t = demand for a certain product in year t. P t = price of the product in year t. N t = income in year t. 51ECONOMETRIC METHOD: ECONOMETRIC METHOD 2. Simultaneous equation method GNP t = G t + I t + C t I t = a 0 + a 1 GNP t C t = b 0 + b 1 GNP t Where GNP t = gross national product for year t. G t = Governmental purchase for year t. I t = Gross investment for year t. C t = Consumption for year t. 52ECONOMETRIC METHOD: Advantages The process sharpens the understanding of complex cause – effect relationships This method provides basis for testing assumptions Disadvantages It is expensive and data demanding To forecast the behaviour of dependant variable, one needs the projected values of independent variables ECONOMETRIC METHOD 53UNCERTANITIES IN DEMAND FORECASTING: UNCERTANITIES IN DEMAND FORECASTING Data about past and present markets. Lack of standardization:- product, price, quantity, cost, income…. Few observations Influence of abnormal factors:- war, natural calamity Methods of forecasting Inability to handle unquantifiable factors Unrealistic assumptions Excessive data requirement 54UNCERTANITIES IN DEMAND FORECASTING: UNCERTANITIES IN DEMAND FORECASTING Environmental changes Technological changes Shift in government policy Developments on the international scene Discovery of new source of raw material Vagaries of monsoon 55COPING WITH UNCERTAINTIES: COPING WITH UNCERTAINTIES Conduct analysis with data based on uniform and standard definitions. Ignore the abnormal or out-of-ordinary observations. Critically evaluate the assumptions Adjust the projections. Monitor the environment. Consider likely alternative scenarios. Conduct sensitivity analysis 56Market planning: Market planning Current marketing situation - Market, Competition, Distribution, PEST. Opportunity and issue analysis - SWOT Objectives- Break even, % market share… Marketing strategy- target segment, positioning, 4 Ps Action program- Quarter 1, Q2, Q3…. 57 You do not have the permission to view this presentation.
