Digital Engineering
Digital engineering revolutionizes the design of complex products and systems through the integration of models, simulation, and other digital tools. Modeling and simulation are emerging as key engineering tools in all parts of the product design lifecycle, and ASME is developing standards to provide guidance at the forefront of advancements in modeling and simulation, digital twin technology, advanced manufacturing (AM), and artificial intelligence and machine learning (AI/ML).

The MAM Manufacturing and Advanced Manufacturing Standards Committee was formed to coordinate, promote and foster the development of standards or related products that provide rules, guidance, and examples of the design, manufacture and quality assurance of additively manufactured parts or relating to advanced manufacturing. There are four subcommittees under the MAM Standards Committee in addition to the working group on additive manufacturing for nonmetallic materials applications.
Additional proposals are under consideration, including a practical, best practice guide on design for AM workflow practices, and a guideline document for suppliers and aircraft manufacturers on FAA Type certification processes and documentation. The NMEx Working Group is developing documents relating to nonmetallic, Materials Extrusion (ME), a type of Additive Manufacturing (AM) or 3D Printing (3DP).

There are three PSD Subcommittees, responsible for developing toolboxes for the three technical areas of the PSD-1 Standard.
The PSD Committee is using Innoslate, a model-based systems engineering (MBSE) tool, to write PSD-1 in the cloud with the goal of also publishing PSD-1 in the cloud. It is envisioned that a company can integrate their procedures with the cloud-based standard so that their procedures can easily be updated when a new edition is published. Users would also be to access the standard from multiple devices, such as phones and tablets.

Charter: To develop, review and maintain a technology neutral standard for design of plant systems for nuclear facilities, including power generation; fossil power generation facilities (e.g., coal, natural gas); oil refining; oil and natural gas production; petrochemical; chemical; and hazardous waste plants and facilities. This standard provides processes and procedures for organizations to:
(a) conduct process hazard evaluations and analysis in the early stages of design that
(1) advance as the design matures and
(2) provide structure to the development of a quantitative risk assessment;
(b) incorporate and integrate existing systems engineering design processes, practices and tools with traditional architect engineering design processes, practices and tools; and
(c) incorporate and integrate risk informed probabilistic design processes, practices and tools with traditional deterministic design processes using reliability and availability targets. The focus of this standard is to provide requirements and guidance for design processes, practices and tools that will provide a means for organizations to develop safer and more efficient system, structure, and product designs with quantified safety levels.
