Hybrid simulation modelling of the software process

The paper proposes the combination of three traditional modelling methods (analytical, continuous and discrete-event) into a unique hybrid two-level modelling approach to address software process simulation modelling issues. At the higher abstraction level, the process is modelled by a discrete-event queuing network, which represents the component activities (i.e. service stations), their interactions, and the exchanged artifacts. At the lower abstraction level, the analytical and continuous methods are used to describe the implementation details of the introduced activities.
