Automated Guided Vehicles systems (AGVs) are considered the most flexible type of material handling systems. These vehicles are equipped with a variety of functions such as guidance and routing systems to traffic management and load transfers. The experience showed that almost all AGV-systems must be customer-designed. This requires an automation system-architecture which allows to distribute the hardware and the functionality as it is required. The aim of this research is to use description Logics as an attempt to develop a tool, which allows to design AGV's system architectures (Layouts) and its associated environments (world models) to deduce the databases from it and to simulate the operation of designed systems. The authors of the paper focus mainly on traffic management and propose the usage of methods from the area of knowledge representation as a basis to serve this purpose. A given application scenario is modelled using Description Logics. Thus a description logic-based system can be used to represent and query the application data. In the given case then the DL system will serve as a central unit for answering queries of the AVGs traffic on a given path or trace. These queries may concern the accessibility of a given block or whether an AVG has to stop, etc. By the use of DL we intend to provide an Integrated tool for AGV-systern and operation planning, operation-simulation, data base system deduction.
