This paper deals with the flow line con trol using the perturbation analysis approach. The per turbed system is analysed in order to determine the perturbation propagation rules under the deterministic similarity assumption. The second part focuses on carrying out a local search based method, to obtain a new jobs' sequencing when control deviation in real time becomes intolerable. This adaptive procedure is based on a simulated annealing method. The last part concerns the robustness of scheduling policies. The expected delay due to disruptions is analysed for some particular situations, and an application to the exponentially distributed duration of the disruption is considered for illustration.
