In this paper, we suggest a framework that allows for the simulation-based performance assessment of algorithms for cooperative transportation planning. Therefore, we consider a coupling architecture that connects simulation models of the logistic system and the transportation planning algorithms. The center point of this architecture is a blackboard-type data layer between transportation planning system and the simulation engine. We provide detailed information on how the different subsystems communicate and how each system triggers events of the other systems. In a case study, we show how the suggested framework supports the required performance assessment.
