Planning Tasks
This page is accessed via Operational Planning > Power Data > Planning > Planning Task.
A planning task represents a particular use of the LP/MIP optimization engine within Oracle Transportation Management. The parameter "GENERATE PLANNING TASK MODEL FILES" indicates whether to generate planning task model files during bulk plan. The default is False, so no planning task model files are generated, (otherwise there could be a lot). These files could be useful for support to research optimization issues.
Note: There are glog.mip properties that may be useful for you.

Updating a Planning Task
- The Planning Task ID shows the task for the details shown
- The Problem Timeout is the maximum amount of time FICO XPRESS OPTIMIZER should spend on this class of problem. This value is overridden by the LOCATION CAPACITY OPTIMIZER MAX RUNTIME parameter.
- Specify the Problem Optimality Threshold. Doing so causes Oracle Transportation Management to look at the tolerance percentage. For example, x% means that the final solution chosen would at the most be x% away from the optimal. Parameters, specific to a planning task, will override the default values in the Planning Task record.
- The Max Problem Size is the maximum size of a problem basis (i.e. non-zero elements in the basis array).
- Specify the Branch and Bound Gap %. When you are optimizing, this field sets the tolerance between the last optimization results and the current results. If the current result is within the gap specified here, then the optimization will stop since it has reached an acceptable gap level. In other words, this is the percentage that the solution can be different from the expected optimal. That is, if the optimal solution is expected to be $100, and the current best solution is $104.90 (and this field = 5), then the solution $104.9 is returned since it is within 5% of the expected optimal.
