Slide 22 GoldSim Technology Group LLC, 2007 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

Slide 23 GoldSim Technology Group LLC, 2007 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.

Slide 24 GoldSim Technology Group LLC, 2007 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
