The INDUSTRAT simulation runs on personal computers. Each team uses a personal computer for decision input and hands in their decision on a diskette or sends to Administrator it via network. The decision entry system offers the opportunity to employ the "what if" approach decisions. The system allows statistical and graphical analyses that teams may deem necessary in addition to the standard studies. The instructor processes the submitted decisions using another personal computer, runs the simulation and generates output, which is printed out and sent to teams on diskettes or via e-mail. The teams use it on their computers for decision making.
