Term
Describe the stages of problem solving
Definition
Intelligence
Design
Choice
Implementation
Monitoring
Term
What are the stages of decision making?
Definition
Intelligence
Design
Choice
Term
What is the difference between problem solving and decision making?
Definition
The decision making phase is only intelligence, design and choice where problem solving includes and goes beyond decision making.:
Term
Describe 3 different types of decision support systems
Definition
Term
Define the term: Management Information System?
Definition
A MIS is a integrated collection of people, procedures, databases and devices that provide managers/decision makers with information to help achieve organisational goals
Term
What are the 3 problem solving approaches?
Definition
Optimization
Satisfying
Heuristics
Term
List a few examples of output reports created by a MIS system
Definition
- Scheduled report
- Key-indicator report
- demand reports
- exception reports
- drill down reports
Term
List a few examples of functional areas that a MIS supports
Definition
- Financial MIS
- Manufacturing MIS
- Marketing MIS
- HR MIS
- Accounting MIS
Term
What is a DSS?
Definition
Decision Support System
A organised collection of people, procedures, software, databases and devices that are in place to support managerial decision making and problem solving activities
Term
Why are DSS's used?
Definition
DSSs are used to bring structure to the unstructured problems that are found within a organisation.
Term
What are the main components of a DSS?
Definition
A database, model base, dialogue manager and links to external sources such as internet, corporate intranet and other external databases.
Term
What are the 4 capabilities of a DSS?
Definition
- Support for problem solving phases
- Support for different decision frequencies
- Support for different problem structures
- Support for various decision-making levels
Term
Compare a DSSs to a MISs briefly
Definition
- A DSS is usually used to support unstructured problems and a MIS usually deals with structured problems.
- A DSS supports individuals, small groups and the entire organisation and a MIS supports primarily the organisation
- A DSS supports all aspects and phases of decision making but doesn't replace the decision maker (people still make decisions) where as some MISs make the decisions and replace the decision maker
Term
Define the term artificial intelligence
Definition
Computers with the ability to mimic or duplicate the functions of the human brain
Term
List the types of AI systems
Definition
Robotics
Visions systems
Natural Language Processing
Learning systems
Neural networks
Expert systems
Term
Briefly explain Robotics
Definition
Robotics involves developing mechanical or computer devices that can paint cars, weld object etc
Term
Briefly explain Vision systems
Definition
Vision systems include hardware and software that allow computer to capture, store and manipulate visual images and pictures.
Term
Briefly explain Neural Language Processing
Definition
Allows a computer to understand and react to statements and commands made in a natural language (Eg. English)
Term
What are the 3 levels of voice recognition?
Definition
Command - recognizes dozens to hundreds of words
Discrete - recognised dictated speech with pauses between words
Continuous - Recognise natural speech
Term
Briefly explain Learning Systems
Definition
A LS is a combination of software and hardware that allows a computer to change how it functions or reacts to situations based on feedback it receives
Term
Briefly explain Neural Networks
Definition
A Neural network is a computer system that can act like or simulate the functioning of the human brain.
Term
Briefly explain Expert System
Definition
A system that gives a computer the ability to make suggestions and act like an expert in a particular field.
Term
Who is generally involved when creating a expert system?
Definition
Domain expert
Knowledge engineer
Knowledge user
Term
What is a domain and domain expert (in relation to expert systems)
Definition
A domain is the area of knowledge and a domain expert is a expert in that area
Term
What are the characteristics of a expert system?
Definition
- Can explain reasoning or suggested decision
- Can display "intelligent" behavior
- Can draw conclusions from complex relationships
- Can provide portable knowledge
- Can deal with uncertainty
