Implementing refined descriptive sampling into three-phase discrete-event simulation models

This article examines the behavior of refined descriptive sampling (RDS) on a civil engineering problem and focuses on the statistical comparison of random sampling (RS) and RDS. The problem considered is the aggregates quarry of Bejaia city. A discrete event simulation model is built using the activity cycle diagram and an application is then developed under the simulation system PSim, in Turbo Pascal programming language. The simulation of aggregates quarry is carried out to measure its performance using both sampling methods to generate input variables. Variance reduction and efficiency are deduced. The results prove the efficiency of RDS over RS.
