Abstract :
We consider a special case of the precedence constrained scheduling problem of n unit execution time jobs on two parallel machines without preemption: the precedence constraints are chain-type and each job can be processed on only one of the two machines. We show that this problem is NP-complete in general, and we derive an approximation algorithm with constant worst case guarantee.
