Introduction FMS is a complex system consisting of elements like workstations, automated storage system and material handling devices such as robots and AGVs.
In recent years, AGVs are widely used in FMS to transport various materials around a manufacturing facility or a warehouse due to their flexibility and compatibility.
Y.C.Ho and H.C.Liu [4] proposed multiple-load AGV in material transport processing and get the best pickup scheduling rules according to throughput criteria in the simulation analysis.

Introduction Silicon carbide is a group IV compound semiconductor showing unique properties, that allow to consider it as a true surface-science 'laboratory' [1]: the charge polarization of the Si-C bonds makes SiC a polar compound, midway between GaAs and ZnSe [2]; the existence of hundreds of tetrahedral SiC polytypes [3] rises fascinating fundamental problems and opens the way to many potential technological applications.
Thanks to the large lattice mismatch of ~ 20%, this interface may be considered as a model of high lattice mismatch heterostructure of covalent materials, where ab initio simulations are still affordable.
