ISC 410 - Decision Support Systems
I. COURSE NUMBER AND CREDIT:
ISC 410 - 3 S. H.
II. COURSE TITLE:
Decision Support Systems
III. COURSE DESCRIPTION:
Decision support systems and expert systems and their
implementations are examined in this course. This
course discusses the manager's responsibilities for
problem solving and decision making and about those
areas in which computers can be used as tools to gain
the insight needed to support selection of decision
alternatives.
IV. PREREQUISITES:
ISC 329 or permission of instructor.
V. JUSTIFICATION:
This course will be an elective in the proposed CIS
minor. This course will be taught irregularly. This
course provides in-depth study of two relatively new
areas of information systems. Class size of 35 is
expected. The course is not being submitted for
General education certification.
VI. COURSE OBJECTIVES:
Upon completion of this course, the student will be
able to:
A. Distinguish among data processing systems,
management information systems, and decision
support/expert systems.
B. Integrate the major components of decision
support systems (DSS) and expert systems (ES),
including systems with the following features:
stored data retrievable through a DBMS, manage-
ment science models operating on the data to
produce derived measures supporting managerial
decision making, and expert knowledge on how to
use available data and management tools under
varying levels of uncertainty.
C. Capture decision rules based on knowledge
provided by an acknowledged expert and codify
those rules as assertions, rules, and ad hoc
procedures.
D. Analyze how information is used to solve
problems.
E. Utilize commercial spreadsheet and database
integrated packages to develop "what if"
simulation models to support the decision-
making process.
F. Describe when/how heuristic expert systems
models may be used to complement more
analytic decision-making frameworks, such as
spreadsheet models.

spreadsheet, database, graphic and
statistical software for "what if" analyses
