The research deals with the topic of Parallel Machine Programming (PMS). It focuses on the problem of large-scale scheduling, where the number of jobs is very large and much greater than the number of resources. The solution is to allocate and sequence the jobs on the resources, such that they can be completed on time or with the least possible delay. PMS is a classic problem, both in industrial engineering due to its relation to resource optimization, and in computational mathematics of combinatorial analysis. Cases with few jobs and resources, have been satisfactorily solved by optimization models, larger cases are addressed with heuristic methods and acceptable solutions are achieved. Large-scale scheduling is a relatively new problem, but its presence is growing due to the trend towards smaller production batches for a more diverse product offering. The literature on large-scale cases is still scarce. The thesis includes two papers, one with a review of methods for PMS and another where the performance of heuristic algorithms for large-scale cases is compared. Finally, a modification of the greedy iterative algorithm is developed and it is empirically verified that its performance increases considerably.
