ICKEPS 2007 runs various simulators to be manipulated via models in integrated planning systems. These simulators will be used to evaluate plans produced by the competitors' tools, providing an (indirect) way of evaluating the KE technology used in each tool.

The interaction with the simulators is as follows:

Interactions with the simulation environment will be logged to provide quantitative data used to evaluate the performance on the simulated domains.


Simulator providers do not need to implement their own port listeners and dispatchers. They just have to be extended to read and write agreed state and plan data. As a consequence, simulators can be executed individually.

The setting that we are working with and the consequences on the hardware/software infrastructure are exposed here.

We use a small c++ server that per communicates via TCP/IP via port listening and dispatching. The simulation server (see manual for a description of its functionality)

We provide a Java client as a support for the competitors to perform the connection to the server and the communication. A small-sized client called (written in Java) is provided in source code. It is up to the competitors to use the provided client or not, so that they can participate without using it. The only thing is to open a port to connect to the server and exchange text/file data. For this we we have given a simple ASCII-protocol to send data and command line parameter information through the net to call a simulator and receive its output.

As a consequence, one can actually operate the server via telnet.

For experimenting with the server you may also download the VEGA tool. This extended client includes functionality for displaying geometrical objects, such that simulators can - in principle - provide their internal state information to the competitors (this implies that the simulator would send commands like line and polygon)
