  1. SIML A template language for an extensible data driven decision  support system to support policy making Ren Bauer Supervised by Hye-Chung Kum

  2. Outline • What is a decision support system (DSS)? • Active vs. Passive • Model vs. Data driven • Related Work • Design of a DSS • SAS/Internet Markup Language • What’s it for? • What’s it look like? • How’s it work? • Future Work • Questions

  3. What is a DSS? • Database A computer based system to support decision making [1] • Model • Decision context • User Interface

  4. DSS Taxonomy • Passive • Provides information, no suggestions • Active • Provides information and suggestions • Cooperative • Provides information and suggestions • Takes user feedback to provide improved suggestions [2]

  5. DSS Taxonomy • Communication-driven • Support multiple people working on the same task • Data-driven • Emphasizes access to a time series of data • Document-driven • Manages unstructured documents • Knowledge-driven • Provides problem solving expertise stored as facts, rules • Model-driven • Emphasize access to and manipulation of a model [3]

  6. Related Work: Policy Support • Most systems rely on Models • Bangkok 2010 study [4] • Long-range Energy Alternatives Planning System • Positives • Can provide effective suggestions for new policies • Backed up by real math • Negatives • Lots of input: difficult to apply in new situations • Not applicable to situations which do not fit models

  7. Related Work: DSS Design [5]

  8. Social workers needed a better way to extract useful information SIML: What’s it for? • Lots of data • Child Welfare • Food and Nutrition Services • Work First

  9. SIML: What’s it look like? ssw.unc.edu/ma

  10. SIML: How’s it work? • The SIML environment includes: • Templates • External files • Compilation engine • User writes a configuration file • SIML (XML based) • Specify template, dataset, variables, etc. • User runs compilation engine • Combines configuration and template files • Produces SAS/Internet output file • User opens output in a browser • Broker generates HTML from output and external files • Browser displays HTML to user

  11. SIML: How’s it work?

  12. Advantages • Extensibility • Adding new pages • Generating new views of existing data • Usability • Systems knowledge • Basic knowledge of SAS

  13. Future Work • Further Adaptability • Ease of integration • User Personalization • Adaptive Menus • More active support • Integration of policy data We’ve noticed a recent increase in your work first cases. Ashe county has experienced a sharp decrease since their implementation of policy WF-9000 in 2011Q1. Click herefor more details.

  14. Recap • Computerized system to help people make decisions Questions?
