We in this paper have proposed the sequential-ring (S-Ring) model of EGC systems and a biobjective formulation of the EGC optimization problem. Unlike the previous work, we use true multiobjective optimizers in solving this problem. The testing on three real-world elevator systems has revealed the possible trade-os between the objectives and offer a valuable insight into the problem.
