There are several forms of forecast error calculation methods used, namely Mean Percent Error, Root Mean Squared Error, Tracking Signal and Forecast Bias.We examine the problem of developing supply contracts that encourage proper coordination of forecast information and production decisions between a manufacturer and distributor of high fashion, seasonal products operating in a two-mode production environment.Understanding and predicting customer demand is vital to manufacturers and distributors to avoid stock-outs and maintain adequate inventory levels.While forecasts are never perfect, they are necessary to prepare for actual demand.This work has been partially supported by the National Natural Science Foundation of China (No.71301076, 71401075), Natural Science Foundation of Jiangsu Province (BK20130771) and the Research Fund for the Doctoral Program of Higher Education of China (20133219120037).
The pricing conditions needed to ensure an efficient solution vary depending on the degree of demand forecast improvement between periods and the manufacturer's access to forecast information.So you can consider MASE (Mean Absolute Scaled Error) as a good KPI to use in those situations, the problem is that is not as intuitive as the ones mentioned before.You can find an interesting discussion here: Look at Measures of Forecast The forecast error needs to be calculated using actual sales as a base.Demand forecasting is the art and science of forecasting customer demand to drive holistic execution of such demand by corporate supply chain and business management.
Demand forecasting involves techniques including both informal methods, such as educated guesses, and quantitative methods, such as the use of historical sales data and statistical techniques or current data from test markets.This is the same as dividing the sum of the absolute deviations by the total sales of all products. The advantage of this measure is that could weight errors, so you can define how to weight for your relevant business, ex gross profit or ABC.The only problem is that for seasonal products you will create an undefined result when sales = 0 and that is not symmetrical, that means that you can be much more inaccurate if sales are higher than if they are lower than the forecast.AB - We examine the problem of developing supply contracts that encourage proper coordination of forecast information and production decisions between a manufacturer and distributor of high fashion, seasonal products operating in a two-mode production environment.
