Modeling User Temporal Behaviors Using Hybrid Simulation Models

This paper presents a simulation model structure that allows build different types of users behavior using workload models. To develop this simulation structure a combination between continuous and discrete models is detailed. In order to formalize the composition of the discrete models defined, DEVS formalism is used. Five different types of user temporal behaviors are specified as a result of the structure proposed: static user, periodic user, once in a lifetime user, unpredictable user and continuously changing user. Then, our proposal gives a context that it could be used in any simulation process that requires a set of requests produced by users as input.
