IMsProblemCalculationSettings.Details

Fore Syntax

Details: Object;

Fore.NET Syntax

Details: object;

Description

The Details property determines type of calculated criterion problem.

Comments

If the Details property contains object of the type:

IMsTargetProblem. Optimal control problem is calculated. The problem consists in finding such values of controlling variables, at which condition of criterion function optimization is fulfilled.
IMsForecastingProblem. Forecasting problem is calculated. Models included into the problem are calculated consequently in each scenario point: firstly, all models are calculated by the first scenario point, then all models are calculated by the second scenario point, and so on.

Fore Example

Executing the example requires that the repository contains a modeling container with the MS identifier containing a criterion function with the TARGET_PROBLEM identifier.

Add links to the Metabase, Ms system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    MsKey: Integer;
    Problem: IMsProblem;
    CalcSettings: IMsProblemCalculationSettings;
    Calculation: IMsProblemCalculation;
    TargetProblem: IMsTargetProblem;
Begin
    mb := MetabaseClass.Active;
    // Get modelling container key
    MsKey := mb.GetObjectKeyById("MS");
    // Get criterion problem
    Problem := mb.ItemByIdNamespace("TARGET_PROBLEM", MsKey).Bind As IMsProblem;
    // Create problem calculation parameters
    CalcSettings := Problem.CreateCalculationSettings;
    // Get criterion problem parameters
    TargetProblem := Problem.AdditionalDetails.Item(0) As IMsTargetProblem;
    // Determine type of calculated problem
    CalcSettings.Details := TargetProblem;
    // Calculate problem
    Calculation := Problem.Calculate(CalcSettings);
    Calculation.Run;
End Sub UserProc;

After executing the example optimal control problem is calculated.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.Ms;
…
Public Shared Sub Main(Params: StartParams);
Var
    mb: IMetabase;
    MsKey: uinteger;
    Problem: IMsProblem;
    CalcSettings: IMsProblemCalculationSettings;
    Calculation: IMsProblemCalculation;
    TargetProblem: IMsTargetProblem;
Begin
    mb := Params.Metabase;
    // Get modelling container key
    MsKey := mb.GetObjectKeyById("MS");
    // Get criterion problem
    Problem := mb.ItemByIdNamespace["TARGET_PROBLEM", MsKey].Bind() As IMsProblem;
    // Create problem calculation parameters
    CalcSettings := Problem.CreateCalculationSettings();
    // Get criterion problem parameters
    TargetProblem := Problem.AdditionalDetails.Item[0] As IMsTargetProblem;
    // Determine type of calculated problem
    CalcSettings.Details := TargetProblem;
    // Calculate problem
    Calculation := Problem.Calculate(CalcSettings);
    Calculation.Run();
End Sub;
