This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...

Electric field in hard superconductors with arbitrary cross section and general critical current law

The induced electric field E(x) during magnetic flux entry in superconductors with arbitrary cross section Ω and general critical current law, has been evaluated by integration along the vortex penetration paths. Nontrivial flux motion streamlines are obtained from a variational statement of the critical state, which takes the form of an optimization problem on the finite element dis-cretizatio...

Special Section on Condition Monitoring and Fault Accommodation in Electric and Hybrid Propulsion Systems

In a world where environment protection and energy conservation are growing concerns, the development of electric vehicles (EV) and hybrid vehicles (HEV) has taken on an accelerated pace. Electricity is gaining more importance in critical applications such as transportation (with more electric aircrafts and electric vehicles) where continuity of operation is crucial and there is a growing deman...
