System Planning Flashcards
Designed by individuals working in the field of artificial intelligence.
Expert systems
Advantages of expert systems
Consistency in decision making
A central knowledge depository
Ability to review answers and generate reports
Given a set input, the returned answer is always the same
consistency in decision making
Manages larger database of information than most human experts.
A central knowledge depository
Allows decision makers unfettered access to information they need at any given time.
Ability to review answers and generate reports
Disadvantages of Expert systems
Software lacks “common sense”
The logic is “locked down”
Programming difficulties
Not adaptable
Elements of a system
Interdependency
inputs
process
output
control
feedback
Must be multiple components that interact with each other in a concerted way
Interdependency
Data that is placed into the system from an external source - system users
Inputs
The overall functionality that the system contributes its various components towards achieving
Process
The product of the system. The end result of the various interdependent components of the system.
Output
Operation that works to prevent or correct problems as they occur throughout the process.
Control
An internal control mechanism that allows for the detection and correction of processing problems.
Feedback
Two types of systems
open and closed
These type of systems do not have fixed or permanent boundaries but are instead constantly being re-defined as they interact with the environment.
Open Systems
This type of system is self- contained and isolated from the environment (including other systems).
Closed systems
