Overview of CDT Process

When you use the CDT Cloud Service module, you follow this general iterative process to create and manage CDTs:

• Setup. You define the domain of calculation by selecting the categories and time frame for the calculation of the CDTs.

• Data Filtering. You configure filters that remove input data that might cause errors in the calculation or that might lead to inaccurate or unreliable answers.

• Calculation. You calculate a specific version of a CDT. Different versions of the CDT based on different configurations can be calculated and compared.

• Evaluation. You examine the results of the calculation and determine the reliability and accuracy of the answers. You can prune inaccurate or unreliable results.

• Escalation. When you are satisfied with the results, you can set the escalation path to fill in the holes for partitions whose CDTs were removed during pruning by setting up a search path through the segment hierarchy and the location hierarchy. Then, you can set a version of a CDT as complete.

Within each stage, you set the required parameters. In some stages, once you do that you click Run to initiate the process. To determine when a run is complete, go to the Overview tab and click the Refresh icon in order to see the current status of each stage. If you make changes to a stage, you must re-run that stage and all the relevant stages that follow it as the results of those stages are made invalid by the changes you made.
