One of Period Length, Day, Week, Month (30 Day), Quarter (91 Day), Year.

Enter the length of the time periods for which you are forecasting demand or setting the Reorder Point and Reorder/Order Up to Qty for R,Q-Targets and s,S-Targets inventory policies. This is one of:

  • Period Length – If you have defined periods, this is the length of the defined period. In a single period model, it is the model horizon.
  • Day – This is a single day.
  • Week – The first day of the week is based on the model horizon. For example, if your model horizon starts on 1/1/2015, this is a Thursday, so your forecast week will be Thursday through Wednesday.
  • Month (30 Day) – The first day of the month is based on the model horizon. For example, if your model horizon starts on 1/7/2015, the 30 day period will start on this date. An average of 30 days is used, rather than months of varying lengths.
  • Quarter (91 Day) – The first day of the quarter is based on the model horizon. For example, if your model horizon starts on 1/7/2015, the 91 day period will start on this date.
  • Year – This is a year starting on the first day of the model horizon.

One of Forecast, Targets.

Choose whether you are using forecasting or targets. If an "s,S targets" or an "R,Q targets" inventory policy is being used, then you must select Targets.

Default: Forecast

Quantities

Technology: S

Table: Forecasts

Internal Name: ForecastQuantities

Type: Memo

Enter the anticipated quantities of product needed for each period (forecasting) or the Reorder Point and Reorder/Order up to Qty (targets). Enter a value, then optionally select a quantity, weight or volume unit of measure. If you do not select a unit of measure, the default Quantity Unit Of Measure from Model Settings is used. Commas should be used to separate numbers.

The number of quantities you enter depends on the period you choose and how long your simulation will run. The table below provides examples of how many requirements would be needed for specific simulation lengths and forecast periods (type is set to forecast in these examples).

If Simulation Lasts: Forecast Period is: Enter At Least This Many Quantities:
30 Days Day 30
30 Days Week 5
1 Year Day 365
1 Year Month 12
1 Year Quarter 4
5 Years Year 5
The DOS Window setting in the Inventory Policies data table also affects how many forecast quantities you should set. You should enter enough quantities to cover your simulation duration plus your DOS Window. For example, if your simulation lasts 30 days, your Forecast Period is Day, and your DOS Window is 7 days, then you should enter 37 Quantities, not 30 as shown above.

Use the name of the forecast specified in this table in the Forecast Name field of the Inventory Policies table for the product-site combination(s) that this forecast applies to.
