Purpose Of Forecast • What decisions will be made as a result of the forecast? • Company corporate planning? • Capacity planning? • Manpower planning? • Sales targeting? • Annual budget? • Cash flow? • Production planning? • Inventory requirements? Long-term Short-term
Syncron Demand Forecast Process • Calculates future forecasts based on the demand history and the latest demand. • Checks for any change in the pattern of demand. • Detects increasing or decreasing trends in demand. • Measures and reports on the accuracy of the forecasts including the impact of manual adjustments.

Forecast Error • All forecasts are single point estimates • Demand is usually random • Hence, forecasts always have error • Forecast error = actual demand - forecast • Most important to forecast the error
Trigg’s Tracking Signal • Notifies the user of items where the forecast is no longer keeping track of actual demand.
YEAR ONE YEAR TWO Causes Of Seasonality • Time of year • Public holidays • Sales effort • Annual price increase • Catalogue issue
Volume Density • The volume density facility allows you to define density factors on a calendar basis, and to adjust the demands, forecasts and hence recommended orders to take account of these factors.

Management By Exception Reports Powerful exception reports focus management attention on items where: • Exceptional demand last period • Tracking signal indicates rapid change of demand level • Strong positive trend • Negative trend • Demand class improved or deteriorated • Forecasts amended by management Essential for large inventories

Basic Systems In Stock Control When to order? How much to order? Basic systems provide answers to the questions:
Basic Systems For Stock Control • Fixed order quantity • Fixed order cycle • Min/max system
THE FIXED ORDER QUANTITY SYSTEM MAXIMUM RATE OF USAGE WITHOUT STOCK-OUT **REORDER QUANTITY (Q) *REORDER LEVEL POINT (A) . . . . . . . . . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • . • .

The Inventory Process • The Syncron inventory process recalculates the following inventory values for each product using the latest forecast and associated adjustments • VAU class • Inventory control type • Review time • Buffer stock • Order level
VALUE OF ANNUAL USAGE THE 80 - 20 RULE Products Turnover
ABC Classification • Basis for an ordering policy • Guide to the relative importance of a product to the business • Allows for effective resource management appropriate for a products importance • Means of balancing inventory cost against risk to service
Multi Dimensional Pareto Analysis To separate high volume, low value from low volume, high value
Overview of Multi-Pareto Process • The process works by automatically allocating products to different parameter sets as well as by VAU • Volume (up to 5 different classes) • Frequency (up to 5 different classes) • Importance (up to 3 different classes)
Order Level Order level for a product is an order up to level and the value is used to determine whether an order needs to be placed and how much to order. It is also used to ensure a pre-determined level of service to the customer.
