Abstract:

We consider a parallel‐machine scheduling problem with a learning effect and the makespan objective. The impact of the learning effect on job processing times is modelled by the general DeJong’s learning curve. For this NP‐hard problem we propose two exact algorithms: a sequential branch‐and‐bound algorithm and a parallel branch‐and‐bound algorithm. We also present the results of experimental evaluation of these algorithms on a computational cluster. Finally, we use the exact algorithms to estimate the performance of two greedy heuristic scheduling algorithms for the problem.
