Starting the scheduler

Now that we have adjusted our targets we can start the scheduler and let it form an allocation that achieves our goals. When the scheduler is running we can watch our targets and the map to see the allocations being made.

  1. Adjust the size of the Map Viewer and the position of the conifer harvest and VQO 1-MI2 target charts so that all are visible simultaneously.

  2. Click the Start scheduler button on the Map Viewer toolbar. This will activate the scheduler.

Now you will be able to see the black lines in the target charts fluctuating as the scheduler is making allocations in all 40 periods while trying to achieve a stable solution (see Figure 15, “State of Conifer Yield and VQO targets while scheduler seeks a stable solution”). The black lines represent the current value of the account. When the black lines change less and less frequently the scheduler is getting close to a stable solution. Solve time depends on the complexity and size of the problem and the speed of the workstation that you are using. As you can see from the target chart the conifer yield is reaching the target, and our sample problem should stabilize within a few minutes or less.

Figure 15. State of Conifer Yield and VQO targets while scheduler seeks a stable solution

After the scheduler has been running for a few minutes, the conifer harvest reaches the minimum target; the black lines are even with the red bars. The resulting values for VQO 1-MI2 are displayed by the black lines; all are under the maximum target shown by the blue bars. In this simulation both targets are achieved.


The scheduler allocations will not be visible in the VQO layer, so be sure you have completed previous steps to turn off the VQO layer and turn on the Seral Stages layer. This layer will show changes as the scheduler makes allocations because the thematic content is a function of the age of the forest. We can watch for blocks turning yellow after being harvested to represent the younger Regen stage of development.

  1. Zoom to the full extent of the map by clicking on the Full Extent button.

  2. Move the period selector ahead to period 20 if it is not already there. No changes will be visible if the Map Viewer is in Period 0, since it represents the original conditions of the forest.

  3. Now let's zoom in a little so we can see actual blocks. Don't zoom in too close but just enough so you can see some blocks changing. Use the Zoom In button on the Map Viewer toolbar. This will get you close enough to see the blocks changing colour as the allocation is adjusted. When the allocation has stabilized, the map will stop changing colours.
