Example
In the following example, EntA arrives at Loc1 for a multi-step process requiring the use of resources Res1 and Res2. The first step requires the simultaneous use of Res1 and Res2 for a normally distributed amount of time. ProModel then frees Res1while Res2 performs the second step of the process according to a Lognormal distribution.
