VDE Verlag Berlin und Offenbach, 1997 Abstract: This paper introduces a new approach for the construction of performance models of complex systems integrating software and hardware. Software components are specified using hierarchical coloured GSPNs which extend the well established coloured GSPNs. Hardware components are composed of basic queues taken from queueing networks. Integration of queues into hierarchical GSPNs facilitates the specification of a virtual machine which provides services for software components. Virtual machines are integrated in the coloured GSPN description of the software component via subnet places. This simplifies the description of the mapping of software onto hardware models. Apart from specification convenience, certain analysis techniques also profit from the hierarchical structure, among others we discuss exact numerical techniques, approximation techniques, simulation and hybrid approaches combining different techniques.
