Abstract : This work is based in the domain of the design of manufacturing systems and attempts to respond to the problem statement: "How to optimize the design process of the machining process plans and reconfigurable manufacturing systems, while taking into account: the interactions between processes and resources, the technological constraints imposed by the part to be manufactured"? This response is given via a proposal for the coexploration of the solution space of the process plans and kinematic configurations. A design framework has been formalised which gives a link between the strategic and operational level. With an objective to explore ail solutions at the operational level, an algorithmic approach for the generation of process plans and corresponding machine kinematic configurations of RMS has been formalised, developed, implemented and validated on 3 parts belonging to automobile sector. This approach can be compared to the dynamic constraint satisfaction problem, it exploits the set of possibilities offered by RMS: parallel stru ctures, simultaneous machining .. . The process of generation of process plans is supported by representation of the generated solutions in the form of graphs. For the selection the generated solutions, performance indicators have been defined, structured, and their evaluation approach identified. A particular attention was given to the criterion of quality. An adaptation of the existing approaches was carried out and simulation of geometric deviation in the generated solutions was done. Generated solutions were adapted to be graphically represented and used for the simulation by L1I. This was done to validate the obtained results.
