- Criteria
Criteria are formulated as mathematical expressions to define goals and restrictions of algorithms. This can be:
Name Description Objectives Possible objective criteria for an optimization problem are minimizing MIN or maximizing MAX. Constraints Constraints are restrictions of an optimization problem. Possible criteria are ≤ and ≥.
Limit states Limit state functions for a reliability analysis can be defined using relations ≤ and ≥ and expressions.
For detailed information see Parametric System.
- Design Point
The Design Point is a container with a collection of design entries.
- Parameter
A parameter is an input variable of a simulation model. It is defined by:
Name Description Name The parameter name. Parameter Type The type of the parameter. Possible values are Optimization, Stochastic, Opt.+Stoch. (mixed) or Dependent. Reference Value The reference value (for example,. parsed value for text input). Constant A flag to set the parameter constant. Operation The expression of a dependent parameter. Value Type Definition of the value type. Possible types are defined by a design entry. Deterministic Properties Properties for optimization parameters (for example,. Resolution, Range, Range Plot). Stochastic Properties Properties for stochastic or mixed parameters (for example,. PDF, Type, Distribution Parameters, Mean, Standard Deviation). For detailed information see Parametric System.
- Parameter Manager
The Parameter Manager is a container with a collection of parameters.
- Design
A design is a set of input parameter values and corresponding output parameter values associated with definitions and status information.
Name Description Id The design ID/number.
Parameters Set of input parameter values as design points.
Responses Set of output parameter values as design points.
Criteria Set of criteria.
Duplicates The design ID/number with same the properties.
Status The processing state of the design.
Design States
State Description Pending The design is in the queue and is being processed. Succeeded The design has been processed. Valid values are available for all defined parameters, responses, and criteria and there were no failures during calculation. Incomplete The design has been processed and all defined parameters have valid values. A failure occurred during calculation or at least one (but not all) of the defined responses and criteria has failed. Failed The design has been processed and at least one parameter has no valid value, or all defined responses and criteria have failed. Needs reevaluation The design has been processed but something changed, so a recalculation is required. - Design Manager
The Design Manager is a container with a collection of designs.
