K. review of Amiry 1967 view details Abstract: A problem faced by most managements is the determination of the optimum management information system (MIS), i.e., the proper balance between the costs of operating the system vs. the expected gains provided by improved information for decision-making. Unfortunately, few managers consider both sides of the balance. This article describes a management game developed to study this problem in a British steelmaking plant. A model of the MIS is superimposed on a model of the physical plant. Time delays are simulated by "shadow" information which, although used as the basis for decision-making, lags behind actual conditions by intervals determined from probability distributions reflecting the MIS. Thus different Op's may be simulated by changing the parameters of the distributions. No discussion of the accuracy of the information is included.

    The models are written in GSP language, although one of the more important routines -- CRANE -- is described in an appendix. The models are operational either on an online or dedicated computer -- it is not clear which. The article does not, unfortunately, include any results or summary of experience of the group in applying their findings. It is, nevertheless, worthwhile reading for Fits specialists and simulation designers.
