Discusses the use of simulations to study complex real-life systems in engineering. Describes some of the limitations of using simulations. Identifies some situations in which computer simulations are practical and useful tools for the design, analysis, and evaluation of systems. (TW)

A preengineered building has the advantages of factory production and computerized quality control. Insulation efficiency and a roofing system that enables the entire roof membrane to react a full two inches to any temperature-induced movement are two of the innovations of preengineered building research.
