A testbed architecture for Auto-ID technologies

Purpose - This paper presents an overview on the Auto-ID (Automatic Identification) technologies testbed that has been established at the University of Missouri-Rolla (UMR) with the objective of supporting research, development, and implementation of Auto-ID technologies in network-centric manufacturing environments.Design methodology approach - UMR's Auto-ID testbed uses a unique hardware-in-the-loop simulation methodology, which integrates decision-making model development with the design of networking topology and data routing scheduling schemes, in order to develop, test, and implement viable Auto-ID solutions. The methodology is founded on a 3-level integrated model: controller simulation, distributed controller simulation, and distributed controller simulation with hardware-in-the-loop.Findings - This paper discusses two case studies that highlight the effective use of RFID technology, its potential advantages, challenges, and deficiencies stemming from particular applications. These applications include dock doors, automated guided vehicles, conveyor and automated storage retrieval systems, integration of RFID middleware with programmable logic controllers, and inventory management of time-sensitive materials.Originality value - The paper presents an innovative idea: hardware-in-the-loop simulation methodology to design automation systems. The approach has been implemented on a variety of applications, which are presented in the paper as case studies.
