Using GRASP for optimization of flow production in FJSP problem with transportation operations

In the paper flexible job shop scheduling problem FJSP with transportation operations is analyzed. We discuss the influence of different production factors on makespan. For the analysis of the production process the greedy randomized adaptive search procedure (GRASP) heuristic was used. Experiments with different levels of factors have been considered and compared. The GRASP algorithm has been tested and illustrated with results for the serial and parallel route.
