Recording a Simulation Session : Creating Reports : Interpreting Raw Data

Interpreting Raw Data

The Simulation raw data may be interpreted as follows:

For Activities:
Activity SET_UP A Int
Activity SET_UP N Ext
 
where A and N are active and nonactive, while Int and Ext point to the source of the change (internal, external).
For States:
State OFF I Int
State ON O Ext
 
where I and O are in and out of the state and Int and Ext are relevant to external states only.
For Conditions:
Condition IN_CONNECTED T Int
Condition IN_CONNECTED F Ext
 
where T and F are true and false.
For Data-items:
Data-item FACT I 5 Ext
Data-item DELTA R 3.2 Ext
 
where I and R are integer and real.
For Events:
Event SET_UP X Int
 
 

where X indicates the occurrence of the event

Trace messages describing changes which occurred in a particular step are grouped together and preceded by a line showing the step and the phase number (step number within that time) and the current time.

Also, the moment the trace is enabled, the current values and statuses of all elements in the Simulation scope are placed into the trace file.

A trace file is a record of all the different statuses that occurred during the simulation. Whenever time changed or the state (value) of an element within the scope of the simulation changed, it was recorded. A trace file is often used to examine how a system behaved during a simulation session once the session is completed.
