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.
