How To

• Design Considerations for a Simulator
• Framework Information Settings
• Creating a Calibration Diagram
• Sim Binding Links in 4.7.0+
• Breaking out a mini model for focused work

Also see the TOOL Quick Reference Card.

• Good TOOL Coding Practices
• Tune your TOOL code for memory and/or runtime constraints
• Unit of Measure Conversions
• TOOL Shell Scripts
• Conditional logic for code running in simulation vs calibration
• Informant naming conventions

• Interacting with the user in views
• General View Writing
• View Naming Conventions
• Common History and Background Checks
• Multiple Scenario Display Views
• Feedback views
• Feedback Tracking Methods
• Data directories
  • primaryData - all your source data for your history and calibration usually lives in: /models/<model>/primaryData (note NOT under the version number)
  • referenceData - all the various data that will inform your projections & comparisons in the simulation time /models/<model>/referenceData (note NOT under the version number)
  • viewData - data informing views including: past user interaction, custom aggregation mappings, parameters for reference scenario: /models/<model>/<Version>/viewData

• Ratcheting - Save project specific view interactions for next run
• Defining a project for the project list
• view specific informants
• Getting project specific paths
• Sub-routine package - setup and loading
• Exogenous Variable Switch
• Templates
  • level or intenstive variable projection
  • share variable projection
• Subroutines
  • saturated projection for reference
  • stepwise change

• Boolean Masks
• Bitwise operations
• Projecting a Variable into Simulation Time
• Ranges
• Using maps
  • Many to one mapping with non-summation aggregation rule
  • Apply aging using a map

• Constrained summations
• Sub-shares using categories
• Using a relative propensity
• Scaling/normalizing to a control total
• Table lookup using classify and dimtran

• Model Loading version 4.7.0: From Documenter to SAMM
• Updating model code and diagrams without a full reload
• Run a calibration to produce a history
• Prepare initialization views
• Typical errors and solutions

The articles in this section discuss how to interact with data files external to the model.

• Overview of reading data
• Data Format vs File Format

In general the data files should not be touched! Try hard to take the data file from it's source and manipulate it in the model or in a view to fit the objects you need to file.

If, however, you want to prepare an empty file to then get others to fill in:

• Prepare empty file from documenter

• A Simple Import View

• Reading data into arrays
  • Importing Informant Definitions - Sets and Categories
  • Use create to make set informants from data file and use them for a test load
  • Use create pick apart complicated data files

• Importing and tabulating record-based datasets
• Geographic data
• Reading Beyond 20/20 (.ivt) data

• Creating Import Templates
• Importing/Exporting time slices using a for loop

• Import and create examples - example import() and create() calls

• Export Views
• Export to .csv
• Export to "template" format

• Export examples

• Projecting Into History

Root finding methods. See http://en.wikipedia.org/wiki/Root-finding_algorithm

Brute force:

• Tracking Method - Deviation ratio multiplier
• Tracking Method - Deviation ratio addition

More specialized/sophisticated:

• Tracking Method - Minimizing Root Mean Squared Difference with 5 point bracketing - bi-section variant
• Tracking Method - Minimizing Root Mean Squared Difference with 5 point bracketing - yet to be implemented

• Displaying data with geomap

• Running Data through Documenter
• Model Debugging in SAMM

• Connect to model hosted at whatIf
