Cold supply chain adopting PI controller to maintain Temperature during drug delivery

A pharmaceutical product, especially vaccines, consign a shelf-life predicted by Temperature. A cold supply chain is administered with the correct Temperature from when the vaccines are manufactured, distributed and reach the hands of public health group members and finally to the health care providers vaccinating the public. Demand, supply and market are the key factors in PSCM (Pharma Supply Chain Management). Shelf life prediction of drugs adopting TTT (Time Temperature Tolerance) helps maintain the key factors in PSCM. This paper focuses on maintaining the correct Temperature during drug delivery by utilizing IoT (Internet of Things). A case study is considered and implemented in the Sun Pharmaceutical industry in maintaining the shelf life of the vaccines like Lupride and Degapride in considering the chemical reactions and microbial growth.
