Firstly, the concept of supply chain and supply chain management is introduced. Secondly, enterprise modeling methods, such as CIM OSA, GIM GRAI, PERA and ARIS, are analyzed and compared. The supply chain modeling technology is studied. Then the ARIS based supply chain modeling method is proposed and the supply chain operation reference model is set up. Finally, the applications of ARIS based supply chain modeling method in Shanghai Turbine Generator Co. Ltd. (STGC) is described in detail.展开更多

A numerical implementation of the present equations in one dimension is described. The numerical model is tested for wave propagation in a wave flume of uniform depth with current present. The present numerical results are compared with those of other researchers. It is validated that the present numerical model can reasonably reflect the nonlinear influences of currents on waves. Moreover, the effects of inputting different incident boundary conditions on the calculated results are studied.展开更多
