Abstract

An algorithm that finds an optimal schedule on a single processor for a given set of processes is presented. Each process starts executing after its release time and completes its computation before its deadline and a given set of precedence relations and exclusion relations defined on ordered pairs of process segments are satisfied. This algorithm can be applied to the important and previously unsolved problem of automated pre-run-time scheduling of processes with arbitrary precedence and exclusion in hard-real-time systems.
