The document describes a system concept simulator (SCS) designed for concurrent engineering. It outlines the SCS's use cases and challenges. The SCS workbench prototype allows engineers to develop models, compose simulations by connecting models, configure and schedule simulations, and execute and monitor them. The workbench prototype implements the SCS design using various software components and demonstrates model development, simulation setup, composition and execution functionality. Next steps include improving the simulator interface and adding simulation visualization/monitoring support.
