RiskPattern.Optimistic

RiskPattern.Optimistic property

Gets or sets the percentage of the most likely task duration which can happen in the best possible project scenario. The default value is 75, which means that if the estimated specified task duration is 4 days then the optimistic duration will be 3 days.

public int Optimistic { get; set; }

Examples

Shows how to define risk simulation settings.

var settings = new RiskAnalysisSettings();
settings.IterationsCount = 200;

var project = new Project(DataDir + "Software Development Plan-1.mpp");
var task = project.RootTask.Children.GetById(17);

// Initialize a risk pattern
var pattern = new RiskPattern(task);

// Select a distribution type for the random number generator to generate possible values from (only two types currently supported, namely normal and uniform)            
// For more details see here: https://en.wikipedia.org/wiki/Normal_distribution)
pattern.Distribution = ProbabilityDistributionType.Normal;

// Set the percentage of the most likely task duration which can happen in the best possible project scenario 
// The default value is 75, which means that if the estimated specified task duration is 4 days then the optimistic duration will be 3 days
pattern.Optimistic = 70;

// Set the percentage of the most likely task duration which can happen in the worst possible project scenario 
// The default value is 125, which means that if the estimated specified task duration is 4 days then the pessimistic duration will be 5 days.
pattern.Pessimistic = 130;

// Set a confidence level that correspond to the percentage of the time the actual values will be within optimistic and pessimistic estimates. 
// You can think of it as a value of standard deviation: the more uncertain about your estimates you are, the more the value of standard deviation used in random number generator is
pattern.ConfidenceLevel = ConfidenceLevel.CL75;

settings.Patterns.Add(pattern);

var analyzer = new RiskAnalyzer(settings);
var analysisResult = analyzer.Analyze(project);
var earlyFinish = analysisResult.GetRiskItems(RiskItemType.EarlyFinish).Get(project.RootTask);

Console.WriteLine("Expected value: {0}", earlyFinish.ExpectedValue);
