1. Decision Support Systems MGMT 661 - Summer 2012 Night #7, Part 2 somewhat based on Chapter 12

2. Types of Decisions Structured  routine (maybe even repetitive)  definite procedure Unstructured  no agreed upon procedure refer back to "Types of Information" in Part #1

3. Decision Support Systems supports semi-structured and unstructured problem analysis  probably overkill for structured problems usually model driven allows to ask "What if?"

4. Simple DSS Examples Car Selection Car Selection  how many miles do you drive?  preferred style?  do you have kids?  yadda yadda yadda Inventory Replenishment Inventory Replenishment  past usage (data from accounting database)  projected need (information from CRM)  delivery time (model from Supply Chain system)  "what if" we delay purchase two weeks?

5. DSS Components Input  TPS Data  Other Internal Data e.g. forecasts, reports, spreadsheet calculations  External Data Model Analysis Software  OLAP and data mining  Easy to Use Interface

6. DSS Models Well Known Relationships  layout of production facility  Supply Chain  Organizational Chart  decision tables  spreadsheet calculations Mathematical Models Decision Variables Uncontrollable Variables Mathematical Relationship Result Variables

7. DSS Caveats DSS improve effectiveness, not efficiency. Some people consider group communication tools to be a type of DSS. DSS v. Expert Systems A human queries a DSS, while an ES queries a human. A DSS assists in decision making, while an ES makes decisions. A DSS is for semi-structured problems, but an ES only works well in highly structured domains.

8. Geographic Information Systems special category of DSS combines large databases and maps www.ncddc.noaa.gov/technology/gis/view Screenshot of ArcView
