Interactive Simulation Modeling of Automated Storage Retrieval Systems

Owing to the complexity and enormous cost involved in Automated Material Handling Systems, there is a growing need to use computer simulation in both the physical system and control software design of such systems. Simulation models can be developed to test not only the final system configuration, but also each installation phase. This paper describes the development of an interactive and flexible simulation software for Automated Storage/Retrieval Systems( AS/RS) of the Miniload variety. A modular approach is taken in the development of the simulation software so that the user, through an interactive capability to model an menu, has the AS/RS by selecting a combination of modules that define the AS/RS. The user then enters the values of the system variables specified for each module. This user-defined simulation model is translated into a simulation language source code and then executed.
