W2ME: A workflow meta model for OTO-oriented E-commerce

Workflow is commonly used in e-commerce system as modeling method. In this paper, we proposed W2ME, a process-oriented meta model for OTO-oriented e-commerce. W2ME bases on the traditional activity network model and extends it. Based on the principle of minimum privileges in the authorization problem, W2ME propose the W2MEA algorithm which effectively reduces the complexity for authority management. Simulation results show that W2ME can save 20% CPU occupancy time and has 95th percentile average success rate.
