Abstract

An advanced processing machine interacts with the material handling system, personnel and cell or shop floor controller in real-time via messaging and control. However, current simulation models are normally built with simulation software tools that are not designed to explicitly model machine interactions. In this research, we develop a modular design of simulation tools. One of the fundamental building blocks is the virtual machine module that simulates machine behavior in terms of state change and its interface. The modular design offers the ability to interact with the surroundings via messaging, similar to real machines. The virtual machine can be used to help develop shop floor controllers and machine controllers, and to test different shop floor control strategies interactively. Its control console can be used for operator training as well.
