TOMAS: TOOL FOR OBJECT-ORIENTED MODELING AND SIMULATION

摘要

TOMAS is presented as a softwarepackage specially developed for discrete event simulation of complex control problems in logistic and production environments. Based of the experience, that the major part of simulation-effort on these systems consists of programming algoritms, TOMAS is implemented as a toolbox in the application-development environment Delphi. The design of TOMAS primarily focuses on problem oriented modelling (ease-of-use), communication with problem-owners, speed and flexibility. A TOMAS model is described by means of the process-orientes approach, where processes are 'normal' object-methods instead of threads. For verification and presentation purposes TOMAS supports fiill 3D-animation. TOMAS is now being applied in the simulation of Automated Guided Vehicle-systems for container-transport and for operational scheduling in ERP-environments. Finally, TOMAS will now be further developed to support distributed simulation and will be connected to qualitative modeling techniques.
