Dirac is an AI-driven, model-based production planning platform that connects engineering, planning, and factory execution into a single operational system. By unifying data across PLM, ERP, and MES environments, Dirac automates complex manufacturing planning workflows including engineering changes, assembly sequencing, MBOM creation, routings, and work instructions. Manufacturers use Dirac to transform the product model into the operational source of truth, so manufacturers can launch faster, adapt operations with precision, and scale complex production without losing engineering intent.
