Definisi-definisi
• Systems Definition[Blanchard]:
an assemblage or combination of
elements or parts forming a complex or
unitary whole, such as a river system or
a transportation system
any assemblage or set of correlated
members, such as a system of currency
a coordinated body of methods or
complex scheme or plan of procedure,
such as a system of organization and
management

The Elements of a System
Components - operating parts of a
system (input, process, and output)
Attributes - properties or discernible
manifestations of the components of
a system
Relationships - links between
components and attributes
5
Systems and Subsystems
• If two hierarchical levels are involved
in a given system, the lower is called
a subsystem
• A total system, at whatever level in
the hierarchy, consists of all
components, attributes, and
relationships needed to accomplish
an objective.
6
Classification of Systems
Natural and Human-Made Systems
Physical and Conceptual systems
Static and Dynamic Systems
Closed and Open Systems

Transition and the Systems
Age - The Machine Age (1)
• The way people understand the world
around them:
Reductionism - reduce, decompose or
dissemble anything into simple parts
 Allows for an analytical way of thinking
»Take apart that to be explained
»Explain the behavior of the parts
»Aggregate the explanations to
explain the whole
8
Transition and the Systems
Age - The Machine Age (2)
• The way people understand the world
around them:
Mechanism
• Explain phenomena by using the
relation of cause and effect
9
Transition and the Systems Age The Systems Age
 1940s - end of Machine Age, begin Systems Age
 Doctrines of reductionism and mechanism replaced
by:
Expansionism - all objects/events and
experiences of them are parts of larger
wholes. Focus is on wholes (systems).
More interest in putting things together
than taking them apart.
Teleologism - preoccupied with systems
that are goal seeking, or purposeful

Engineering in the Systems Age
• Must be a team activity where various
individuals are cognizant of the
important relationships between
specialties
• Technical expertise must include
knowledge of engineering and
knowledge of domain
