Distributions
Number and duration attributes (an Action's Duration, a Cost's Amount) accept a distribution that the Simulator samples on every run. Timelines and rollups use its mean.
| Distribution | Formula |
|---|---|
| Beta | =beta.dist(α,β) |
| Binomial | =binom.dist(n,p) |
| Exponential | =expon.dist(λ): λ is the rate, so the mean is 1/λ (=expon.dist(0.25) hours has a mean of 4 hours) |
| Gamma | =gamma.dist(k,θ) |
| Log Normal | =lognorm.dist(μ,σ) |
| Normal | =norm.dist(μ,σ) |
| Poisson | =poisson.dist(λ) |
| Triangular | =triang.dist(a,b,c) |
| Uniform | =uniform.dist(a,b) |
| Weibull | =weibull.dist(λ,k) |
Durations cannot be negative: a sampled value below 0 is drawn again, so a normal duration is truncated at 0. Keep σ well below μ to make the difference negligible.
