system
what is the meaning of system in simpler terms?
a system constitutes a set of interrelated components working together with the common objective of fulfilling some designated need
what are the general characteristics of a system?
- complex combinations of resources
- is contained within a hierarchy
- can be broken down into subsystems
- must have a purpose
- must respond to a functional need
what are the 4 classification of system?
- natural and man-made systems
- physical and conceptual systems
- static and dynamic systems
- closed and open-loop systems
this system came into being through natural processes like river and energy system
natural systems
this system have been developed by human beings like hydroelectric power system
man-made systems
this system is made up of real components that occupies space
physical system
this system is a series of abstract concepts, organization of ideas, specifications and plans
conceptual system
this system have structure but without activity like highways and warehouses
static system
this system combines structural components with activity like production system combined with manufacturing facility
dynamic system
this system is relatively self-contained and does not significantly interact with its environment like chemical equilibrium process and an electrical circuit
closed system
this system interacts with their environment like support capability
open system
what is the collection of component systems that produce results unachievable by individual systems alone
system of systems (SOS)
what are the 4 elements of system?
components
attributes
relationships
state
what is the element of which the system is composed? also referred to as part of the system
components
this is the properties of the individual components which characterize the system
attributes
this refers as between (pairs of) components so that the components interact to support the system’s functionality (common purpose)
relationships
this refers to the values of the attributes and relationships at a particular moment
state
TRUE OR FALSE.
A component have an effect on the properties and behavior of the system as a whole
true
TRUE OR FALSE.
A component do not depend on the properties and behavior of at least one other component in the set
false
