HRM 3450 Tutorial 13 Notes – Conceptual
Introduction
• The links in this system are conceptual, specifically, the distance of each planet from the
sun, interplanetary and solar gravity, orbital relationships, the distances between
planets at a particular point in time, and other attributes.
• A diagram of a home networking system.
• The links in this case are a mixture of physical wires and (intangible) wireless
connections.
• Sometimes the nature of the links is important only in terms of providing the proper
interface connections to the components.
• A simplified diagram of part of the inventory control portion of a sales system.
• The relationships between the components in this case are temporal (i.e., related to
time).
• For example, inventory from a previous sale must be deducted from stock before we
process the next order
• Otherise e a’t proise deliery of goods o the e order eause e do’t ko
if we still have sufficient goods in stock to fill the order.
• With these pictures and ideas about systems in mind, we will define a system
• A system is a collection of components linked together and organized in such a way as
to be recognizable as a single unit.
• A general representation of a system is shown
• The linked components that constitute a system also define a boundary for the system.
• Anything outside the boundary represents the environment that the system operates or
presents itself within.
• The environment may interact with and affect the system in various ways.
• The reverse is also true.
• The interface between the system and its environment is an important characteristic of
the system.
