This paper presents an advanced simulation model for short-termscheduling of complex hoist lines. This problem, generally found in aerospaceand electroplating industries, includes several hard constraints that should beconsidered: single shared hoist, heterogeneous recipes, eventual recycle flows,and no buffers between workstations. Different heuristic-based strategies areincorporated into the computer model in order to improve the solutions generatedover time. The aim is to reduce the number of products that must be discardedwhile minimizing the makespan. In addition, a graphical user interface wasdeveloped for quickly evaluating simulated schedules.
