Harvest Scheduler
Simulation software for harvest planning
Harvest Scheduler is a system for simulating forest harvesting.
Harvest Scheduler predicts the production of volume by log type of each harvesting crew, and the net stocked area reduction of the harvest unit in which each crew is working. Predictions are made on a daily basis based on crew production rates and availability. Reports are generated at different time-scales from daily through to annual. Key reports show production through time by forest, crew and log type.
| Benefits | Features |
|---|---|
| Scenario Management | Organise scenarios into folders. Try variants to test “what if“. Manage access within the organisation. |
| Variable timescale | Results are available at daily, weekly, monthly, 3-monthly, quarterly, annual, and financial yearly intervals. |
| Production estimates | Estimates of log yield in tonnes by grade, crew, and harvest unit at any timescale. |
| Prediction of area harvested | The depletion of the net stocked area is predicted for any timescale. |
| Multi-user system | Built on SQL Server to provide a secure and reliable planning system for multiple users. |
| Cut plan selection | Allows for the selection of a specific cut plan by the crew in a harvest unit. |
| Flexible production rates | Crew production can be specified at three levels. |
| Control over crew availability | A full calendar of workdays allows for detailed production estimates. |
| Powerful reporting | Standard PDF reports, interactive charts, and data export to Excel for more detailed analysis. |
| Integration | Harvest unit information can be sourced from GeoMaster and yield cube information referenced from Yield Table Manager. |
Harvesting Crews
A crew has a unique name and may represent an actual harvesting crew, or a token crew to trail a required increase in capacity.
Each crew has a move-and-set-up time, a specified number of days worked, a harvest list, and a production rate (crew and / or harvest unit specific). The harvest list is a sequenced list of harvest units that the crew will harvest in the specified order.
Each harvest unit refers to a cutting pattern selected from the harvest unit’s assigned yield cube and has an option to specify a finish date (or harvesting will continue until completion of the area).
Harvesting Units
A harvest unit is any area of forest that will produce log volume and grade more-or-less uniformly across its extent.
Hence one yield cube is sufficient to predict the yield. A harvest unit could be a setting (the ATLAS Harvest Manager system recognises a hierarchy of Forest, Block, Harvest Area, and Setting), or a stand (ATLAS GeoMaster uses Forest, Compartment, and Stand).
A harvest unit must have a plant date so that yields can be indexed by age. Yield cubes are selected and referenced from ATLAS Yield Table Manager. The net stocked area at the start of the simulation must also be known.
Reporting
All reports can be generated at different time scales: daily, weekly, monthly, quarterly, and annually.
Production charts and reports show the log production by grade through time. Area charts and reports show the depletion of the net stocked area from harvesting. Gantt charts show the sequence of harvest units the crews work through over time. Production and area report data can be exported to Excel.
Harvest Scheduler uses Yield Table Manager to provide Yield Information. Harvest units can be sourced from GeoMaster stands or from Harvest Manager settings/ harvest areas or manually entered.
Reports can be exported to Excel for more detailed analysis.
Scenarios
A scenario is a self-contained set of planning data from which a simulation can be run to produce all the standard reports.
Scenarios are used to try variants of the inputs (crews, production rates, harvest list etc.), and to update the starting point for a simulation.
