Enhanced array constructors (vector & matrix)

Specify array items using expression: vector(days, OutputX) Use keywords row and col to initialize arraysvector(days, row) [ 1, 2, 3, 4, 5, 6, 7 ]

matrix(Set3, Set4, row) matrix(Set3, Set4, col) matrix(Set4, Set4, if(row==col, 1, 0))

[ 1, 1, 1, 1 ] [ 1, 2, 3, 4 ] [ 1, 0, 0, 0 ] [ 2, 2, 2, 2 ] [ 1, 2, 3, 4 ] [ 0, 1, 0, 0 ] [ 3, 3, 3, 3 ] [ 1, 2, 3, 4 ] [ 0, 0, 1, 0 ] [ 4, 4, 4, 4 ] [ 1, 2, 3, 4 ] [ 0, 0, 0, 1 ]

vector(Set4, if (row == 2 || row == 3, 1, 0)) [ 0, 1, 1, 0 ]

matrix(Set3, Set4, (row-1) * GetRowCount(vector(Set4, 1)) + col) [ 1, 2, 3, 4 ] [ 5, 6, 7, 8 ] [ 9, 10, 11, 12 ]


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


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)


Jade: Outlook (cont.)

Component element Scenarios in GoldSim

– Scenario element– Scenario management & running scenarios

Script element Resources Strategic Planning Module Additional Dashboard enhancements


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


Components


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


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


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.


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
