Smart Manufacturing and Digital Manufacturing are the evolving descriptors for the business and operational application of advanced cyber technologies in manufacturing. The term ‘Manufacturing’ refers to anything that is ‘made’ - energy, chemicals, materials, and objects. This workshop brought together experts in smart manufacturing and digital manufacturing, industry, and academia, cutting across the sectors of continuous, batch, discrete and hybrid manufacturing. The workshop objectives during 2/23-24/2015 were to build a common understanding and use of terminology and to then delineate research areas and opportunities with greater precision. The workshop report is an independently developed assessment and summary of the results reflecting a consensus by each breakout group on relevant definitions and research areas and their scope. A key outcome of this workshop is the expression of the report structure itself - (1) the semantics of Smart Manufacturing and Digital Manufacturing, (2) the fundamental role of modeling and (3) the particular descriptions of the ASCPM research areas.
