Simulation Event Attributes

Detailed Description

Attributes to define stochastic and priority properties.

Attribute for an event in the context of simulation. When simulating one or more generators, at each instance of time there will be one or more transitions enabled. In order resolve this non-determinism in a defined way, each event may be equipped with either one of the following properties.

• a SimPriorityEventAttribute to prioritise events
• a SimStochasticEventAttribute to determine timing by random variables

Note that the SimEventAttribute just holds the data to define the properties, a semantic implementation is in faudes::ProposingExecutor. The current implementation also stores simulation state data (ie evaluations of random variables), but this is likely to change in a future revision.

As a faudes attribute, SimEventAttribute provides token io and is prepared for the use in the context of a faudes container. The file format of a set of events equipped with simulation attributes is illustrated by the below example for the simulation of a simple machine:

<SimEvents>
 
% machine start: prioritised event with priority 100
"alpha"    
<Priority> 100  </Priority>  
 
% machine finsh: gauss distributed event with mue=10 and sigma=5, relative to guard
"beta"   
<Stochastic> +Trigger+  +Gauss+  <Parameter> 10  5  </Parameter> </Stochastic>
 
% break down: gauss distributed event with mue=20 and sigma=5, relative to enabled time
"mue"   
<Stochastic> +Delay+  +Gauss+  <Parameter> 20  5  </Parameter> </Stochastic>
 
% machine repair: prioritised event with priority 100
"lambda"    
<Priority> 100  </Priority>  
 
</SimEvents>
