Execution Monitor

In addition to the graphical tools available to visualize the knowledge structures of a problem solving model, KSM also provides an execution monitoring tool which shows the step-by-step evolution of the reasoning process. This tool uses the representation of the generic knowledge model and, according to the state of the reasoning, it attaches coloured labels with the name of the task that is being realized to the knowledge units that are involved in the reasoning. These labels have four different colors and meanings:

Green:

Represents that a task has been called.

White:

It represents that a solution has been found.

Yellow:

The same task is called again in order to produce new results following a non-deterministic search.

Red:

Represents a fail in the execution of the method, i.e. that no solution has been produced.

Figure 10 shows a screen hardcopy of the kind of display provided by this tool with the public transport management model.
