Business viewpoint
The business viewpoint addresses the concerns of the stakeholders involved. It defines
values and objectives in establishing an IIoT system in its business and regulatory
context. It also defines how the IIoT system achieves the objectives through identifying fundamental system capability. Typical stakeholders in the viewpoint are
business decision-makers, regulatory bodies, and system engineers.
Usage viewpoint
The usage viewpoint addresses the concerns related to expected usage of an IIoT
system. It is typically represented as sequences of activities. Activities are a coordination of more basic unit of work, which is called a task. A task is carried out by
stakeholders assuming a role to deliver intended functionality or capabilities of the
system. Here, a role is a set of capacities assumed by stakeholders to initiate and
participate in the execution of some tasks or functions in an IIoT system. Note that
assignment of roles to stakeholder is business specific. Typical stakeholders described
in the viewpoint are any individuals who are responsible for the specification of the
IIoT system (e.g. system engineer) and those who are responsible for execution of
the activities (e.g. production manager, machine tool operator etc.).
Functional viewpoint
The functional viewpoint defines and clarifies the functional components in an
IIoT system, their structure and interrelation, interactions and interfaces with their
surrounding environment as well as other systems to support the overall activities
described in the usage viewpoint.
Implementation viewpoint
The implementation viewpoint deals with the technologies utilized to implement
functional components and communication scheme among them.
Among the four viewpoints, we use the business viewpoint and the usage viewpoint in the paper because we want to clarify and discuss the values provided by
introducing IIoT system in product recovery processes.
34.3 Use Case: Customized Disassembly
34.3.1 Background and Motivation
Disassembly refers to the process of breaking down an End of Life (EOL) product
into a separate part in order to recover value from its constituent components as well
as materials. Because each individual product has been used in different conditions
and maintenance policies, the conditions and the residual life of their components
significantly differ from each other. Consequently, different products have different
sets of usable (or profitable) components and materials to be recovered. This causes
