Seeing Double (For Good Reason): Using Digital Twins To Improve Pharma Processes There are multiple reasons why engineers cannot visit a facility, not least the disruption wrought by 2020’s COVID-19 pandemic. Even when visits can be accommodated, there are time delays. The technological solution that has reverberated through industry, including pharmaceuticals, is digital twins. A digital twin is a virtual model of a process, product, or service. 1 The pairing of the virtual and physical worlds not only enables systems to be adapted or repaired from afar, but the approach also further enables the analysis of data and monitoring of systems to avoid problems before they even occur. This can prevent downtime, foster new opportunities, and allow future-state solutions to be modeled by using digital simulations. This article looks at the digital twins concept and considers how the pharmaceuticals sector can take advantage of this particular crest of the digital transformation wave.
