16. Ida Release • Beta version of Ida should be available late this year • Release is planned for first quarter of 2008 • We are also currently designing some new features for the Jade release

17. Jade: Outlook • Vista compatibility • Common Dialogs; Search integration • Registry Access, Standard User; • User Account Control • Performance improvements (Part II) • Multi-core / multi-processor support • OpenMP implementation for array functions • Multi-threaded or parallel run execution • 64-bit support; WoW64 for 32-bit application • Licensing (checkout, improved stability and usability)

18. Jade: Outlook (cont.) • Component element • Scenarios in GoldSim • Scenario element • Scenario management & running scenarios • Script element • Resources • Strategic Planning Module • Additional Dashboard enhancements

19. Components • Special version of a locked Container • Contains encapsulated logic • Data exchange must use element interface (user-defined inputs/outputs) • Can resemble look and feel of a GoldSim element • Can be saved as .gsc file • Can be added to Insert Element menu • One or many instances of the Component can be added to the same model • All instances can automatically be updated when new version of the component becomes available

20. Components

21. Scenarios • New Scenario Element • Scenario Management: • High-level scenario management to carry out several simulations representing different scenarios • Display results of multiple scenario runs in combined charts and tables

22. Script Functions and Element • Executes embedded VBScript or Jscript using Microsoft Windows Scripting Engine • User defines element interface (inputs and outputs), which can be accessed within the script as variables. • Can be used when simple, custom coding is required • Function Example: Function ToCelcius(fFahrenheit) ToCelcius = (fFahrenheit – 32) 5 / 9 End Function

23. Resources • Resources are continuous or discrete scalar non-negative quantities (electric current, #pumps). • Different types or pools of resources can exist in a model. The current available amount of a resource will be represented by a new Reservoir-like Resource element. • Resource consumption is either instantaneous or gradual. • Discretely-acquired resources may be ‘borrowed’ and returned when the action is completed, e.g. a piece of equipment or an operator. • A resource requirement in a trigger would, if necessary, wait for the resource to be available before starting the triggered action.

24. Strategic Planning Module • Enables GoldSim to model and simulate projects • Enhanced conditional containers capable to represent project tasks • Adds support for Work Breakdown Structure • Generating, capturing, and reporting on costs (and revenues) • Simulating the availability of, competition for, and management of resources • Post-simulation results analysis
