This paper demonstrates how to design and implement the emulators for a real-world
automated manufacturing system (AMS). In order to develop and validate system control software for managing AMSs, most laboratories have constructed an experimental test using actual manufacturing equipment. These experimental systems typically occupy a large amount of lab space and require considerable human expertise to operate. In this paper, a scenario-based development
environment for the equipment design and implementation are described. The intended advantage of the proposed environment is that, the designer can make an experimental test in a computer and does not need the actual manufacturing equipment. The proposed environment can be used to design and
implement a real-world automated manufacturing cell controller at National Taiwan University of Science and Technology (NTUST). We start with a new methodology to model the operation sequences of the system’s equipment (i.e., machine) called scenario. Modeling methodology is the key to the application of scenarios to automated manufacturing systems. The scenarios methodology
is able to clearly depict the communication signals for the equipment. And it also can be used to model the resource utilization features within a manufacturing system. Using scenario, we have developed an emulator for an automated manufacturing cell which faithfully replicates the operating characteristics of an ensemble of physical equipment that would typically comprise an AMS.
