Dornier According to the above, in our object oriented simulation the single transport objects were sent continuously through the defined stations in which they seize certain recources (e.g. airport, aircraft) for

a defined time. Using the petri network technique, the problems occurring with slacks will be registered

automatically and recorded in the chosen specification. zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA

Figure 13 shows a user caused break during the executed simulation, where an aircraft on its flight has been stopped to view the load of the aircraft. This can be seen out of the protocol. Two aircraft are on flight from zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA

S t u t t g a r t :

an Ilussin 76 (JL769) and a Transall C160 (~16039). The loading list of the IL 76 No. zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA

time of this aircraft at Stuttgart was 13.452 hours after the start of the operation.

Output Processor

The data produced by the simulation will be processed statistically during the simulation. Figure 14 gives an overview of the data that can be produced by the simulation. After the simulation ends, the results may be evaluated using the TOPAS-Outputprocessor. They can also be presented as dynamic graphics during he running simulation using the integrated graphic software of the simulation language
