Demand Forecast

This table is used within the Simulation experiment only. It allows you to estimate expected customer demand for certain products over the specified period of time. The table uses periodic or historic data for demand forecasting.

You can as well specify the sales forecast in this table that is used in case of MRP Inventory policy.

In contrast to the Demand table, the record in this table can be applied to a customer (to work with the data on placed orders of a single customer) or a site (representing aggregation of all placed orders).

Column Description

Facility

Defines the source of demand. Double-click the corresponding row cell to choose among the available (previously defined in the DCs and Factories table) facilities.

Product

The product required for the site defined in the Facility column. Double-click the cell and select the product from the drop-down list of the available products (previously defined in the Products table).

Type

Type of demand definition:

  • Periodic demand - select this option if the demand is of repetitive nature: a certain volume of products is ordered in a certain period of time. You can define quantity and period values in the Parameters column.
    Alternatively this option is used to create demand in case no historical data is available.
  • Periodic demand with first occurrence - same as Periodicdemand, but has the First occurrence parameter (defined in the Parameters column), that defines the date on which the first demand occurs. No demand will be generated before this date.
  • Historic demand - use this option if you have historic demand data (this could be order records from CRM). Define the data in the Parameters column.

Parameters

The column cell contains editable data of the chosen demand definition type:

If the Type is set to Periodic demand, the cell will display Period=5.0, Quantity=10.0, First occurrence: First day.

If the Type is set to Periodic demand with first occurrence, the cell will display Period=5.0, Quantity=10.0, First occurrence: First day.

If the Type is set to Historic demand, the cell will display total q=0.0, standing for the sum of all ordered products for the specified period of time.

Time Period

Defines the period of time (from the previously defined in the Periods table) for the demand forecast specified in the Parameters.
