Abstract:

In a site with one set of blast furnaces that must feed two steel mills separated by over 13 kilometers, alloca- tion of hot pig iron is a complex subject owing to the long cycle times and the large number of parameters in- volved in the decision making. Simulation of the trans- portation appears as an ideal solution to tackle this com- plexity. However, allocation priorities are stategic issues that change in time, as does, if less often, the available railway layout.

A simulation based decision support system has been developed to integrate in the current torpedo tracking application that works around these difficulties by gen- erating the simulations dynamically from three sources: a database model of the transportation network, the dy- namic database that holds the current state of the tor- pedo wagons (through the tracking application), and a shared, updatable knowledge base made up of several sets of rules and priorities, and conditional paths of rule- set selection. The knowledge base is now being built on expert knowledge and current strategies, and will pro- vide a framework for user-accessible update.
