Calculate Forecast

Explanation

This activity is used to perform a forecast calculation on the selected vehicle part. When you have evaluated material and capacity requirements, you may want to run a new forecast on another operational budget to analyze the results. Therefore, when you perform this calculation, you need to enter the year for which the forecast is required. To do this click Forecast Calculation from the pages listed under the Pages section and enter the required year. Forecast calculations can be run as a background job as it can be time consuming. You can search for the background job in the Background Jobs page to make sure it is being executed or has been completed. 

Forecast calculations are based on the operational history records of a maximum of three years. The calculation of a yearly forecast is based on operational budget values, and the proportional numbers are calculated based on the operational history and yearly forecast values.

In the Forecast Information page, you will find calculated averages for up to 3 years of operational history, yearly forecasts based on operational budgets and proportional numbers based on these two values. The forecast is calculated per maintenance group, per vehicle, and for all sub parts in the vehicle part structure. You can view:

• Parameter data from the forecast per maintenance group.
• Parameter data from the forecast where all maintenance groups per part are summarized. The weighted historical average value per serial, forecast values per year and the proportional will be calculated after the number of serials which belongs to a maintenance group.
• The product structure for the calculated vehicle, broken down to all serial parts. For all serial parts, a calculation like the one done in the Per Maintenance Group tab for vehicles will be conducted. The same proportional numbers will be used for both serial parts and the vehicle which these are a part of. Besides forecast per year, forecast per month is also shown. The forecast per month is used for due date calculation for serials. The planned average value for triggering operational parameter per maintenance group will be updated automatically.
• Yearly maintenance for each maintenance event code per forecast year. Based on the forecast values per year, the yearly maintenance for each maintenance code is calculated according to the intervals defined in the maintenance plan. These calculations pertain to vehicle and serial parts. The serial revision is taken into consideration because the intervals are often changed with a new revision.

Calculation results can be viewed in the Forecast Calculation Results page.

Prerequisites

N/A

System Effects

The forecast calculation will be executed on a selected year. Thereafter, you can view the estimated requirements for serials, spare parts, and consumables. The forecast also estimates the requirement for workshops and different resources (person groups).
