Using the Entity Explorer
Having made a minimal conversion of a Mosel model to an Xpress Insight app, there are no custom views, and no app-specific user interface. Instead, you can explore your model, its variables and entities via the Entity Explorer, which is accessible from the view navigator on the left of the App page.
|
Note To use the Entity Explorer, you need to have the DIRECT_DATA_VIEW system authority, which is automatically included in the
Advanced User,
Administrator and
Developer authority groups. Contact your system administrator if the Entity Explorer is not accessible.

The figure shows the salient details of the Entity Explorer following an
Xpress Insight run of the converted example app.
The Entity Explorer
Clicking on an entity name causes a visual representation of the entity to be presented in the main browser panel. You can select to view only the input entities or only the results entities by making the relevant choice in the drop-down list. You can also choose to make hidden entities visible with the Show Hidden checkbox.
The following figure presents a composite image of the representations of all listed entities.
Composite View of Entity Explorer Results
Labeled items are:
- The NA input array as initialized from the folio.dat file.
- The SHARES input array as initialized from the folio.dat file.
- The RET array, which has SHARES as an index set. Again, this was initialized in the folio.dat file, and provides reference information about the ROI of each type of share.
- The RISK array, which represents the riskier share types, as initialized in the folio.dat file.
- The parameter values as established in the Mosel model.
- The maximization objective result Return - a scalar.
- The frac array, containing a representation of the optimal proportions of share types to invest in. This is the same data as was written out to the result.dat file in the original, pre-Xpress Insight model.
