How new technologies can improve cold chain management?

There is a growing attention towards technological solutions that can improve cold chain management. This paper analyzes pros and cons of four alternative solutions (Data Loggers, Time Temperature Indicators, semi-passive RFId and Wireless Sensor Networks), paying particular attention to the overall balance of costs and benefits. Thanks to this preliminary study, a solution based on Wireless Sensor Networks has been designed to monitor more efficiently the ice-cream supply chain of a prominent company (Nestlé Italy) and its impacts on overall cold chain performance have been evaluated.
