Unified reference model for smart manufacturing (IEC 63339:2024)
IEC 63339:2024 specifies the unified reference model for smart manufacturing (URMSM) using a terminology and structure, and establishes criteria for creating reference models, as specializations, that support smart manufacturing. The terminology and structure comprise a set of common modelling elements, their associations, and conformance criteria. These common modelling elements address aspects and perspectives of products and production and their lifecycle considerations.
The URMSM enables an approach for creating multiple models based upon a reference model that is sufficient for understanding significant relationships among entities involved in smart manufacturing (SM) and for the development of standards and other specifications.
The URMSM specifications in this document accommodate consistent, coherent, compatible specializations for relevant aspects of manufacturing systems consisting of equipment, products, and services within the domain of manufacturing. Provisions of this document are applicable for a new smart manufacturing reference model (SMRM) or elaboration of existing SMRM capabilities, for example, improving capabilities for analysis of opportunities and synthesis of technological advances, and improving interoperability of new and existing systems.
This document is not intended to prescribe interoperability considerations or data schemas of models. Standardization of content relative to models will be the subject of other standards and texts specific to those model domains.
Einheitliches Referenzmodell für Smart Manufacturing (IEC 63339:2024)
Modèle de référence unifié pour la fabrication intelligente (IEC 63339:2024)
IEC 63339:2024 spécifie le modèle de référence unifié pour la fabrication intelligente (URMSM) à l’aide d’une terminologie et d’une structure données, et établit des critères pour la création de modèles de référence, en tant que spécialisations, qui prennent en charge la fabrication intelligente. La terminologie et la structure comprennent un ensemble d’éléments de modélisation communs, leurs associations et des critères de conformité. Ces éléments de modélisation communs traitent des aspects et des perspectives des produits et de la production, ainsi que des considérations relatives à leur cycle de vie.
L’URMSM permet de créer de multiples modèles en partant d’un modèle de référence qui est suffisamment développé pour comprendre les relations significatives entre les entités impliquées dans la fabrication intelligente (SM) et pour développer des normes et d’autres spécifications.
Les spécifications relatives à l’URMSM dans le présent document permettent des spécialisations cohérentes et compatibles pour les aspects pertinents des systèmes de fabrication composés d’équipements, de produits et de services dans le domaine de la fabrication. Les dispositions du présent document s’appliquent à la création d’un nouveau modèle de référence pour la fabrication intelligente (SMRM) ou à l’affinement des capacités d’un SMRM existant (par exemple, l’amélioration des capacités d’analyse des opportunités et de synthèse des avancées technologiques, et l’amélioration de l’interopérabilité des systèmes nouveaux et existants).
Le présent document n’a pas pour but de prescrire des considérations d’interopérabilité ou des schémas de données de modèles. La normalisation du contenu relatif aux modèles fera l’objet d’autres normes et textes spécifiques à ces domaines de modèles.

INTRODUCTION
“Manufacturing” refers to a range of human activities, from handicraft to high tech, and is
commonly applied to industrial production, where raw materials and parts are transformed into
finished goods on small to large scale by a series of interconnected processes. Smart
manufacturing (SM) is an emergent characteristic of manufacturing achieved by digital
technologies, gradually built up through digital transformation, combining diversity and
uniformity, demonstrating continuous value delivery by a highly complicated collection of
processes interacting on different time scales. In today’s manufacturing landscape,
manufacturing is no longer characterized as a set of serial processes, but instead as a highly
interconnected set of distributed processes that are able to cooperate on different time scales.
A set of supervisory processes achieve coordination of these distributed processes using links
that enable dynamic response to changing conditions in demands, supply, environment, energy
and, other human or naturally caused probabilistic events. Since these probabilistic events are
not known before occurrence, they often are disruptive and result in changing conditions.
The purpose of smart manufacturing is to accommodate those disruptive events, while
supporting the introduction of new technologies and methods in a coordinated manner across
the variety of customers, suppliers and stakeholders at various stages in the value chain.
Building upon the common knowledge and results found in IEC TR 63319 [9] – A meta-
modelling analysis approach to smart manufacturing reference models, as depicted in Figure 1
– this document specifies the unified reference model for smart manufacturing (URMSM) to
create purpose-specific domain and application reference models for smart manufacturing
initiatives by specifying the necessary structure and terminology for expressing such models.
The URMSM is applicable across the many domains and applications found within a
manufacturing enterprise.
Smart manufacturing reference models (SMRM), which conform to the requirements of this
document, provide SM standards developers and SM practitioners with better opportunities for
implementing models of production systems and products that take full advantage of
technological innovations. These innovations occur during:
• analysis and synthesis using models of manufacturing,
• application of new materials, processes and facilities for manufacturing,
• understanding the emergence of digital twin concepts and other smart manufacturing
technologies.
The URMSM is not one model or one model visualization. The URMSM is the specification for
a family of reference models that share structural and behavioural properties intended to
promote interoperability.
NOTE Subclause 8.2 provides more information regarding relationships among models and derivation relations.
The URMSM brings together concepts from existing works, both standards and practice, to
support the variety of existing reference models, the adaptation of existing reference models
for new uses, and the emergence of new reference models, all of which take advantage of the
evolution in manufacturing technologies.

Figure 1 – Using URMSM
The model-based approach of the URMSM has two major structural components. The first is a
modelling framework to support various arrangements of manufacturing elements into
conceptual configurations deemed pertinent to domains of manufacturing enterprises. The
second is the conceptualization of semantic models that reside within the modelling framework.
A concise URMSM terminology supports both the modelling framework and the conceptual
semantic models.
Since smart manufacturing is essentially a human conception of improved manufacturing
technologies and practices, differences in interpretation of that concept can lead some
practitioners to over-simplify the complicated nature of perspective and property interactions in
today’s manufacturing systems. Objectifying the notion of ‘smart’ for manufacturing is a
challenge since developers and practitioners have been getting smarter about manufacturing
for over 200 years already.
For IEC work in a domain of similar complexity, the author of [48] summarizes "smartness" in
the domain of Smart Cities as follows:
Smartness is an emergent characteristic of a system
• achieved by digital technologies,
• explicitly architected and engineered to reduce complexity,
• gradually built up through digital transformation,
• permanently demonstrating value delivery,
• combining diversity and uniformity,
• coordinating and cooperating between all the stakeholders.
Considering this characterization, the URMSM provides the means for creating reference
models for smart manufacturing that enable emergence of more digitally oriented, engineered
solutions for delivering additional value from manufacturing operations. The result is improved
performance aspects with integrated and intelligent use of processes and resources in cyber,
physical and human spheres to create and deliver products and services, which also collaborate
with other domains within enterprises' value chains [16].
This document identifies a collection of criteria for arranging aspects of the smart manufacturing
domain as reference models. The important relationships among manufacturing elements
enable useful examination and derivation of practical designs in order to fulfil a defined purpose,
and to maintain and improve the resulting system through methods for analysis and synthesis.
The URMSM provides insight into the modelling of aspects of manufacturing elements to
consider when developing new elements. Smart support methods for conducting that
development or modification can require an evolution from existing practice to a more unified
model-based approach.
– 10 – IEC 63339:2024 © IEC 2024
This document can be used to support the development processes of smart manufacturing, and
to assure coherence and compatibility during the development of standards.
This document identifies ways to apply those aspects of manufacturing and the acumen
essential to developing a smart manufacturing model for a particular industrial enterprise.
The URMSM goes beyond the representational features of manufacturing elements to enable
examination of interactions among those elements through the use of models to address issues
arising in the course of smart manufacturing initiatives.
Expectations regarding the outcome of a satisfactory URMSM are:
• enabling the examination of value within a value creation network;
• enabling a range of appropriate libraries such as use cases, interface definitions, models
for semantics, information and data, and international standards as modelled views relative
to modelling purposes for particular smart manufacturing situations;
• enabling representation as a multi-dimensional space composed from various collections of
aspects to accommodate particular modelling purposes, such as aspects of production,
aspects of product, aspects of smart technology, and their relationships over their respective
life cycles;
• enabling assurance that information is consistently structured using standards for
information, data and modelling languages, without ambiguous meaning, by applying
semantic models and techniques;
• enabling efficient usability for the creation of tailored smart manufacturing models that
address a stakeholder’s particular concerns.
The URMSM supports all three modalities of interoperation (unified, integrated, and federated)
that can co-exist within a modelling framework, albeit with varying extents of effectiveness and
efficiency (see ISO 11354 [17]). Having a formal understanding of modelling frameworks
enables more effective and efficient utilization of frameworks.
Clause 4 specifies extents of conformance to URMSM based upon meeting the requirements
and recommendations in their entirety, as full conformance, or for particular subclauses, as
partial conformance.
Clause 5 presents aspects of manufacturing commonly associated with 'smart manufacturing'.
Clause 6 presents modelling concepts essential for constructing suitable reference models in
the domain of smart manufacturing.
Clause 7 establishes examination and derivation criteria for interoperation of aspects in
manufacturing.
Clause 8 presents ways to use the URMSM to create purpose-specific reference models.
Clause 9 presents use cases for the URMSM and a progression of capability markers that
indicate maturity in the application of the URMSM.
Clause 10 discusses ways to manipulate and use reference frameworks for extended analysis
and synthesis for systems used in smart manufacturing.
Annex A presents concept areas of smart manufacturing.
Annex B provides a formal foundation for the URMSM approach including a modelling
framework for URMSM.

UNIFIED REFERENCE MODEL FOR SMART MANUFACTURING
1 Scope
This international standard specifies the unified reference model for smart manufacturing
(URMSM) using a terminology and structure, and establishes criteria for creating reference
models, as specializations, that support smart manufacturing. The terminology and structure
comprise a set of common modelling elements, their associations, and conformance criteria.
These common modelling elements address aspects and perspectives of products and
production and their lifecycle considerations.
The URMSM enables an approach for creating multiple models based upon a reference model
that is sufficient for understanding significant relationships among entities involved in smart
manufacturing (SM) and for the development of standards and other specifications.
The URMSM specifications in this document accommodate consistent, coherent, compatible
specializations for relevant aspects of manufacturing systems consisting of equipment, products,
and services within the domain of manufacturing. Provisions of this document are applicable
for a new smart manufacturing reference model (SMRM) or elaboration of existing SMRM
capabilities, for example, improving capabilities for analysis of opportunities and synthesis of
technological advances, and improving interoperability of new and existing systems.
This document is not intended to prescribe interoperability considerations or data schemas of
models. Standardization of content relative to models will be the subject of other standards and
texts specific to those model domains.

3.1.1
aspect
labelled designation for a collection of concepts in a particular context
EXAMPLE functional, structural, information, security, availability, customer.
Note 1 to entry: An aspect is often expressed as a view across one or more model for a manufacturing system.
Note 2 to entry: Elements of an aspect can have functional, non-functional or other kinds of descriptors.
Note 3 to entry: The identification of an aspect is often the result of prior knowledge, experience and practice in the
domain to which the aspect applies.

3.1.2
aspect interaction
relationship between two or more aspects (3.1.1) where one aspect influences or is influenced
by the presence of another aspect
Note 1 to entry: Influence includes but is not limited to dependence and control.
3.1.3
business
series of processes, each having a clearly understood purpose, involving one or more person,
realised through the exchange of information and directed towards some mutually agreed upon
goal, extending over a period of time
[SOURCE: ISO/IEC 15944-20:2015, 2.2]
3.1.4
complex
decision situation characterised by unordered decision variables, and ill-defined categories,
criteria and dependencies
3.1.5
complicated
decision situation characterised by enumerated decision variables, and well-defined categories,
criteria and dependencies
3.1.6
concern
matter of relevance or importance to a stakeholder (3.1.20) regarding a manufacturing system
or element thereof
Note 1 to entry: Stated concerns are useful when relevant to the purpose of the modelling effort and refer to specific
rather than categorical difficulties, problems, or requirements.
Note 2 to entry: Concern expression takes many forms, including among others: as questions about features or
characteristics, as a keyword label for many related matters, and as expected quality attributes of the manufacturing
system or its products and services.
[SOURCE: ISO/IEC/IEEE 42010:2022, 3.10, modified – added "regarding a manufacturing
system or element thereof”]
3.1.7
dimension
coherent collection of aspects (3.1.1) relevant to a manufacturing domain (3.1.12)
Note 1 to entry: The coherence requirement of the dimension can result in a collection of aspects that are
unordered, partially ordered, fully ordered, or related in some other manner, or not ordered in any way (see 6.4 on
dimensional coherence for further information).
3.1.8
element
tangible or intangible constituent of a manufacturing system or of a product
Note 1 to entry: A constituent can range from atoms of raw material or logical constructs or items of information
through manufacturing models or equipment and entire factories, plants or supply chains and added value networks
to finished goods, and software and services.
Note 2 to entry: While
