Simulation of a distributed expert-based information provision mechanism

In earlier work, a model o f the information provision mechanism (IPM) as a collective o f cooperating entities, each expert in a particular function associated with information interaction and provision, was proposed This was originally a descriptive and analytical model, but it was also suggested as a design model In order to investigate its design potential, its general validity, and some architectural issues, five simulations o f the model using human beings as the functional experts, were run. The results o f the simulations indicate that the general model is valid as a design tool that the functional specifications are at least necessary, and that a black­ board communication structure with modified distributed control seems optimum for system implementation. They also indicate a partial ordering on the sequence o f function processing, and suggest that messages within such a system need to be typed
