Abstract

In this paper, we consider the problem of scheduling tasks on two dedicated processors where some tasks need to be processed only by the first processor and some others by the second processor; the remaining tasks, however, need both processors simultaneously. Tasks have release dates and have to be scheduled without preemption. The objective is to minimise its makespan. For this problem, which is known to be NP-hard in the strong sense, we propose a lower bound based on processor relaxation and show that it is equal to the optimal solution for a preemptive case. We propose two heuristics with a worst-case analysis and its generalisation to any semi-active schedule. A set of dominance properties are established and a branch-and-bound algorithm is developed and tested on a set of randomly generated instances.
