Behavioral-based performability modeling and evaluation of e-commerce systems
作者：
Highlights：
• We model customers’ shopping behavior with deterministic and stochastic Petri nets.
• We employ hierarchical composition of sub-models to build a performability model.
• We propose taxonomy, specify operational profiles and use discrete-event simulation.
• Highly available e-commerce system will not always lead to higher user-perceived QoS.
• Performability measures are turned into business-oriented metrics for server sizing.
