The problem of relative orbit configurations over a long time intervalsincorporating realistic dynamics, platform differences and operational constraints for safety, station keeping and inter-spacecraft communicationsis addressed. Two different approaches are developed. In the first approach, relative mean orbital mean elements are found through minimizing deviations from reference mean orbit. In second one, relative configurations are found from a reference initial condition through minimizing probability of collision between the spacecraft in the cluster which are propagated numerically through full force models.Effectiveness of the approaches is demonstrated through simulations
