A2D - ACQUIRE TO DECIDE Decision support systems for the inspection and maintenance of infrastructure and engineering structures. A2D, a start-up created in 2017 by academic researchers, has become an expert in the automation of data processing, analysis and interpretation, with a view to actions in the field. The applications we have developed are designed to help people use machines to apply their business know-how at industrial production rates. Fine-tuned control of the entire decision-making chain enables us to characterise the reliability of the decisions proposed by conventional or Artificial Intelligence tools. A2D offers acquisition services (signals, images, videos, etc.) and protocol definition, or processes acquisitions already carried out by client companies or service providers.
