Monte Carlo Simulation A Monte Carlo simulation is a dynamic model of a situation, which results in a picture of the likely operation of the subject being modeled over a period of time Example 16.4 A site concrete mixer produces 1m 3 of concrete at each mixing. During a large pour of concrete, a wet hopper is used in front of the mixer into which the mixed concrete is discharged prior to being loaded into trucks. The wet hopper has a maximum capacity of 3 m 3. The cycle time from discharge to discharge in mixing 1m 3 of concrete is studied and the frequency distribution shown in Table 16.6 results.
