Range Process Simulation Tool (RPST) is a computer program that assists managers in rapidly predicting and quantitatively assessing the operational effects of proposed technological additions to, and/or upgrades of, complex facilities and engineering systems such as the Eastern Test Range. Originally designed for application to space transportation systems, RPST is also suitable for assessing effects of proposed changes in industrial facilities and large organizations.

RPST follows a model-based approach that includes finite-capacity schedule analysis and discrete- event process simulation. A component- based, scalable, open architecture makes RPST easily and rapidly tailorable for diverse applications. Specific RPST functions include:

  1. definition of analysis objectives and performance metrics;
  2. selection of process templates from a process-template library;
  3. configuration of process models for detailed simulation and schedule analysis;
  4. design of operations-analysis experiments;
  5. schedule and simulation- based process analysis; and
  6. optimization of performance by use of genetic algorithms and simulated annealing.

The main benefits afforded by RPST are provision of information that can be used to reduce costs of operation and maintenance, and the capability for affordable, accurate, and reliable prediction and exploration of the consequences of many alternative proposed decisions.
