ABSTRACT

Abstract In this chapter, we show how to compare the performance of stochastic task resource systems. Here, task resource systems are modeled by dynamic systems whose inputs are the task and resource data, given under the form of random processes, and whose outputs are the quantities of interest (response times, makespan). The approach presented here is based on stochastic orders. Several typical examples (some simple, other rather sophisticated) are used to show how orders can help the system designer to compare several options but also to compute bounds on the performance of a given system.
