Background
•
•
Food saftety and traceability have drawn more and more public attention.
•
Auto-ID especially RFID technology brings new opportunities for improving tracking
and tracing process in supply chain.
Paper-based traceability systems are not adequate for timely and accurate tracing of
products.
Intelligent transport items as well as the IT-infrastucture are going to be developed
in the FORFood project for improving safety and traceability in the food supply chain

What is EPCIS?
EPC Information Service (EPCIS) is an EPCglobal standard designed to enable EPC-related data sharing
within and across enterprises. It is the crucial component of the EPCglobal-network (a global approach for
internet of the things) and enables a useful semantic interpretation of Auto-ID data to improve supply chain
transparency and visibility.

Research Objectives
• Investigation and adaption of EPCIS for tracking and tracing in the food supply
chain.
• EPCIS-events generation based on supply chain simulations.
Why Simulation?
• Only few real-world implementations exist that can be directly
examined;
• Simulation can be relatively easily extended for different
application scenarios;
• Large amounts of EPCIS-Events can be generated in short
time for developing and testing High-Level applications.
• Material flow;
What are simulated?
• Identification points with middleware function, which serialized
the reading events into EPCIS-Events with XML binding;
• Abnormalities such as over-threshold temperature, RTI lost,
etc.
• Real-time transmission of EPCIS-Events into EPCIS-based repositories for
developing and testing high-level applications

Contribution and Future Works
Contribution
• Conceptual framework of EPCIS-based tracking and tracing in Auto-ID enabled
food supply chains.
• Suggestions for extension fields related to product EAN code, lot number and
also the temperature values for the EPCIS implementation in the frozen food
chain.
• Development of a method for generating EPCIS-events based on supply chain
simulations.
Future works
•Development of high-level application for analyzing as well as visualizing the
generated EPCIS-Events.
• Development of Supply Chain Event Management (SCEM) applications based
on simulations.
