Decision Support Systems Quiz

What is a common characteristic of DSS?

• Replaces human decision-makers

• Focuses on efficiency over effectiveness

• Supports unstructured or semi-structured problems

• Operates independently of user control

A DSS extends the decision-maker's capacity by:

• Making final decisions autonomously

• Processing time-consuming portions of problems

• Eliminating the need for data analysis

• Reducing the number of alternatives

The core components of a DSS include all EXCEPT:

• Data management system

• User interface

• Hardware procurement system

• Model management system

In the hierarchy of data, the correct order from largest to smallest granularity is:

• Files → Database → Records → Data elements

• Database → Files → Records → Data elements

• Records → Files → Database → Data elements

• Data elements → Records → Files → Database

The DBMS maintains logical independence between:

• Users and hardware

• DSS database and DSS application

• Model base and knowledge engine

• Input devices and output formats

What differentiates a DSS from other information systems?

• Database size

• Model base for analysis

• User interface design

• Data storage methods

Knowledge in a DSS knowledge base is:

• Identical to database information

• Only raw data

• Problem-specific (e.g., rules, heuristics)

• Focused on hardware configurations

In "intermediary mode" of DSS use, the decision-maker:

• Receives scheduled reports

• Interacts via intermediaries

• Uses the system offline

• Operates the system directly

A "directive" decision style is characterized by:

• High tolerance for ambiguity

• Need for structured problems and low ambiguity tolerance

• Reliance on consensus

• Extensive data analysis

Simon's model of problem-solving ends with:

• Intelligence phase

• Design phase

• Choice phase

• Implementation phase
