Wireless sensor network (WSN) technologies are now available to implement real time temperature monitoring systems in food supply chains. The aim of this paper is to examine different types of methods and criteria to establish alerts in decision support systems in perishable food supply chains.
The technology of time temperature integrators (TTI) is used to ensure the safety and quality of temperature sensitive goods such as food and drugs along their entire lifespan. This work aims to provide a better understanding of potential benefits that can be expected from the use of TTIs in terms of supply chain improvement.
