Overview • Decision Support Tools and Analysis • QnD Model and its Use • QnD:Jamaica Version 0.0 • Discussion
Traditional Decision Support Systems • Many definitions, many visions, many versions… • DSS Integrate Tools and Methodologies • Method Descriptions and Tools • Information Storage and Databases • Models • Visualization (examples: maps, graphics, charts…) • Decision analysis (examples: Adaptive management, Multi-Criteria Decision Analysis, Trade-off analysis, Linear Programming)
Challenges in Building DSS • DSS almost always focus on one sector’s (or discipline’s) tools and concepts • Model integration is difficult and technically challenging • DSS are not always helpful in unearthing assumptions • Transparency versus Ease of Use • Integration with scenario planning and communication - “More gaps than links” (Mike Brklacich, 2005)
Useful Questions • Who will use these IGP Decision Support Tools? • What decisions need to be made? • Over time? • Over space? • Adaptively? • How do you or your constituents currently make decisions? • What new techniques are you willing to explore? • What are your information, support and communication needs? • Training/Workshops? Reports? Web Tools? • What does transparency in decisions mean to you? • What does it look like? • What level of transparency is appropriate? And remember…you can always change your mind…
QnD Model • QnD™ – “Questions and Decisions™” or “Quick n Dirty” • A fully integrated Graphic User Interface (GUI) with a flexible model engine • One model - Many ecosystems • Java code / XML inputs • Dynamically instantiated objects • Java-based deployment in web browsers • “Fast Deployment” (weeks/months) • Spatial simulation with GIS linkage • Multiple time steps • Multiple maps/graphs/files for output variables
subComponent subProcess “Simulation Engine” “Game View” • Developer’s point of contact • Integrates information • Objects: Components, Processes and Data • Calculation of state variables • User/Player’s point of contact • Communicates information • “Widgets”: Maps, Charts, Warning Lights, Text, Sliders, Icons, Buttons • User choices – management settings, simulate fast or slow time step, reset
User-Defined “Slow and Fast” Time Steps Management Options QnD:Game View Reset Button “Warning Lights” Tabbed panes with several time series charts Mouse-driven Chart and Text Display Spatial Maps of Ecosystem Indicators
Actors • Players: Interact mostly with the game view. • Explore management responses, adaptive opportunities, trade-offs for different scenarios. • Provide reality checks • Have some interest in the engine structure in their area of interest • Provide ideas and directions for further iterations • Developers: Interact mostly with the engine. • Design and implement engine/game view through XML files. • Provide formal calibration/validations • Implement ideas and directions of Players • Have some interest in the model code subComponent GameDriver.java ModelCreator.java • Coders: Interact mostly with the QnD source code. • Develop java code to expand engine and game view utility • Create new programming code for ideas from Players and Developers… subProcess “Game View” “Simulation Engine” QnD Java Source Code PrimaryGameFrame.java
Genesis Session Prototype QnD Game View and Simulation Engine • Talk about the system, goals, desires • Explore current management options • Gather initial maps/data • Brainstorm about desired management options, relevant information and socio-economic realities • Rough estimate of components, processes and data • Simple information • Deployed in limited circulation for calibration/reality checks Iterative Sessions 1…n Deployed QnD Model • Refine goals, objectives • Explore current and possible management options • Calibrate/Validate engine performance • Revise Game View for relevant management information • Make changes concerning management options, relevant information and socio-economic factors • Player/Developer reviewed components, processes and data • More relevant information • Brainstorm about desired management options, relevant information and socio-economic realities QnD: Development Methodology
