Active Systems
Systems with active temperature control (e.g., air/sea freight containers, refrigerated trucks/cars). (TR39) System with active temperature control. It makes use of electricity or fuel for the compressor to maintain temperature. Examples include refrigerated trucks, temperature-controlled ocean containers, and active ULDs. (TR58) Actively powered system that uses electricity or other fuel source to maintain a temperaturecontrolled environment inside an insulated enclosure under thermostatic regulation (e.g., cold room, refrigerator, temperature-controlled truck, refrigerated ocean or air container). (TR64) (TR72) (Synonym: Active Temperature Controlled System)

Supply Chain Optimization
The application of AI to enhance efficiency, stability, and visibility across the pharmaceutical supply chains, from manufacturing to distribution. An early application of AI was to calculate the most effective route of delivery to several destinations to enable products to be in transit for as short a time as possible and thus support product stability, cost, and sustainability.
