Description
The information needs of the National Launch System program had their beginnings with the Advanced Launch System (ALS). The Technical Reference Document for ALS called for "a Unified Information System (UNIS) to provide, in a timely manner, all the information required to manage, design, manufacture, integrate, test, launch, operate, and support the ALS." UNIS 9 was to provide the link between distributed, heterogeneous workstations which were to make up both the ground and flight information systems. In addition, there was to be an Advanced Launch System Model (ALSYM), "a set of computerized submodels, or tools, which would work together to simulate all aspects of the ALS." These conceptual requirements were transitioned to the NLS program, and UNIS and the system simulation exist today. The current version of the NLS UNIS links geographically dispersed users to databases, analysis tools, program management tools, and communications devices. UNIS development is continuing to provide the ultimate capabilities which were described in the ALS Technical Reference Document. The approach to that development, as well as the current and planned capabilities are described. The ALSYM requirement transitioned as a requirement for a largescale, end-to-end simulation of the Space Transportation Main Engine (STME) development program, named STESYM. The approach being used to satisfy that requirement incorporates object-oriented programming, discrete-event simulation, and knowledge-based techniques to produce a simulation that captures the technical characteristics of the hardware, the processing flows, and the scheduling requirements. The outputs of the simulation will include subsystem and system reliabilities, process infrastructure statistics, schedule performance statistics, and costs. Together, UNIS and STESYM will provide program managers, engineers, logisticians, and other program participants with communications connectivity and the information to support STME program analysis.
