to different processes (e.g., design, manufacturing,
inspection) and business needs (e.g., technical,
commercial, regulatory). Every organization
involved in the product lifecycle relies on this data to
perform its function. It represents the “fuel” behind
the organization's contribution, efficiency, and value:
organizations can create more value and drive faster
innovation by exchanging data across them,
facilitating collaboration.
Unfortunately, fast and reliable data exchange is
also a complex operation that comes with multiple
challenges (Panetto et al., 2019), each of which can
have drastic consequences on organizations, their
operations, their products, and their collaborators. In
this paper, we define and discuss the risks associated
with two major challenges, data interoperability and
data traceability. In the next section we introduce the
data interoperability issue and discuss why the
traditional information standard development process
is inadequate to support the Industry 4.0 fast-paced
environment. We follow by discussing cyber threats,
why manufacturing is a viable target, and how
appropriate data traceability can help mitigate these
risks in this complex environment. Finally, we
conclude and discuss future directions.
2 DATA INTEROPERABILITY
Following this digital transformation of the industry
and the modernization of the adopted communication
technologies, data is now available from all, to all,
and in a multitude of formats. Organizations can
easily connect different software and physical
systems, internally and within their network of
collaborators, as long as these systems speak a
common language.
Unfortunately, today’s manufacturing
organizations are characterized by complex
environments consisting of domain-specific
components such as systems, networks, or machines,
clustered in heterogeneous groups. While the
interaction of these components is crucial for
manufacturing as it supports production processes,
effective interoperability across all elements of the
product lifecycle is a growing challenge (Panetto,
2007). The amount of data produced and consumed
continues to increase due to this growing ecosystem
(of machines, systems, and networks), but so does the
number of data formats. These data are collected from
distributed data sources and therefore do not
necessarily share the same format. Data heterogeneity
is an important factor in data exchange. The different
components of an organization's environment must be
able to unambiguously interpret, use, integrate, and
compare the information exchanged.
These different systems need a common language
to exchange and understand information. The use of
neutral model-based data standards helps provide a
common data format, and thus facilitates
interoperability between all parties involved in an
exchange. Standards are essential for properly
integrating, exchanging, and interpreting data
manufacturers rely on (Sapp et al., 2021). Standards
define an agreed-upon language (data format,
definitions, etc.) for data exchange between the
different systems that consume, process, and produce
data. The lack of standardization results in a
multiplication of information formats that are not
necessarily compatible with each other, making it
difficult for stakeholders to communicate and
exchange data.
Information standards are an important asset for
organizations because they help facilitate business
interaction and support interoperability between
systems, people, and organizations. Information
standardization also saves time and reduces costs by
eliminating the need to have separate translators for
each pair of systems that need to exchange data. The
adoption and implementation of standards by
organizations improves performance,
competitiveness, and transparency given that
standards promote the accessibility of information by
all stakeholders. Information standards are powerful
tools for innovation and productivity and are
therefore key enablers to the evolution and
digitalization of the manufacturing sector. Nowadays,
standards support the full product lifecycle. Product
definition data is represented in ISO 10303
(informally known as STEP) (ISO, 2020).
Manufacturing planning systems can read in STEP
data and generate manufacturing instructions in G-
code (ISO, 2009) or ISO 10303-238 (STEP-NC)
(ISO, 2007). MTConnect Agents (MTConnect
Institute, n.d.) stream machine execution data that
represents an as-manufactured product. Coordinate
measurement system software can read in STEP
product definition data and generate inspection plans
and inspection results represented in the Quality
Information Framework (QIF) (DMSC, 2016).
Despite this, information standards present a
major challenge, which can impact their adoption and
implementation by organizations: the complexity and
current development process length of prominent
standards are incompatible not only with the needs
and pace of the industry but also with the lifespan of
data.
