Chap 9 : Enabling the Organization - Decision Making
IT system used by organizations
Decision support system (DSS)
models information to support managers and business professionals during the decision-making process
Executive information system
a specialized DSS that supports senior level executives within the organization
Artificial Intelligence (AI)
simulates human intelligence such as the ability to reason and learn
Data Mining
typically includes many forms of AI such as nural networks and expert systems. Data mining tools apply algorithms to information sets to uncover inherent trends and patterns in the information.
Three quantitatives models typically used by decision support system
Sensitivity analysis
the study of the impact that changes in one (or more) parts of the model have on other parts of the model
What-if analysis
checks the impact of a change in an assumption on the proposed solution
Goal-seeking analysis
finds the input necessary to achieve a goal
The relationship between digital dashboards and executive information systems
An executive information system (EIS) is a specialized DSS that supports senior level execuitves within the organization
A digital dashboards integrates information from multiple components and present it in a unified display
Four types of artificial intelligence systems
Expert systems
computerized advisory programs that imitate the reasoning processes of experts in solving difficult problems
Neural networks
attempts to emulate the way the human brain works
Intelligent agents
special purposed knowledge based information system that accomplished specific tasks on behalf its user
Types of data mining analysis capabilities
Cluster analysis
a technique used to divide an information set into mutually exclusive groups such that the members of each group are as close together as possible to one another and the different group are as far apart as possible
association detection
reveals the degree to which variables are related and the nature and frequency of these relationships in the information
Stastical analysis
performs such functions as information correlations, distributions, calculations and variance analysis
