ControlRuleSet Class

Represents an immutable set of process control rules that can be evaluated over a RuleEvaluationContext.

Definition

Namespace: Numerics.NET.Statistics.ProcessControl
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.4.0
C# 
public sealed class ControlRuleSet
Inheritance
Object  →  ControlRuleSet

Remarks

The rule engine is intentionally decoupled from control-chart factories. Evaluate rules by calling EvaluateRules(ControlRuleSet) on any series, which creates a RuleEvaluationContext automatically and invokes Evaluate(RuleEvaluationContext).

Obtain a pre-built ControlRuleSet through the static properties on ControlRuleSets, or construct one directly from a collection of IProcessRule instances.

Example

Evaluate rules against an I-MR chart series:

C# 
double[] observations = { 9.0, 11.0, 10.0, 12.0, 8.0, 10.0, 9.0, 11.0, 10.0, 10.0 };

IndividualsMovingRangeChartSet chart =
    new IndividualsMovingRangeChartSet(Vector.Create(observations));
chart.Analyze();

RuleEvaluationResult result =
    chart.IndividualsSeries.EvaluateRules(ControlRuleSets.Nelson);

if (result.HasViolations)
{
    foreach (RuleViolation v in result.Violations)
        Console.WriteLine($"[{v.RuleId}] Point {v.TriggerIndex}: {v.RuleName}");
}

Constructors

ControlRuleSet(IEnumerable<IProcessRule>) Initializes a new ControlRuleSet from the specified rules.
ControlRuleSet(String, IEnumerable<IProcessRule>) Initializes a new named ControlRuleSet from the specified rules.

Properties

Name Gets the name of this rule set, used in EvaluatedRuleSet.
Rules Gets the ordered collection of rules in this rule set.

Methods

(Inherited from Object)
Evaluate Evaluates the rule set against the supplied RuleEvaluationContext and returns all detected violations.
GetHashCodeServes as the default hash function.
(Inherited from Object)
GetTypeGets the Type of the current instance.
(Inherited from Object)
ToStringReturns a string that represents the current object.
