This paper presents Virtual Simulation Objects (VSO) concept which forms theoretical basis for building tools and framework that is developed for system-level simulations using existing software modules available within cyber infrastructure. Presented concept is implemented by the software tool for building composite solutions using VSO-based GUI and running them using CLAVIRE simulation environment. Contemporary e-science tasks often require large amount of computer simulations to be performed. The simulation process today is often characterized not only by computational complexity, but also by structural complexity: solving the science tasks requires composition of resources from different classes - hardware, software, informational, even human resources. All these resources should be integrated and managed in the appropriate way to solve particular simulation tasks.
