This paper addresses the problem of sequencing for the mixed-model assembly lines in the car industry. In the real car productive systems, the sequence is defined by the content and the extraction order of a subset of units, taken from a buffer at the beginning of the assembly line, which is dynamically refilled. The problem consists of defining the sequence of an assembly line in real time to optimize the flow of materials and the requirements of resources on the line. Some results obtained with real data from the factory are shown, and they demonstrate that the heuristic approach performs well in the real productive system where it has been implemented.
