An object-oriented approach to an information and decision support system for railway traffic control
Michele M. Missikoff · 2002
The paper describes the analysis, design, and fast prototyping of MINT, an information and decision support system for railway traffic control. MINT is a complex system that tightly integrates information management and problem solving functionalities, by means of an object oriented approach. The work is characterised by several issues: (i) object oriented analysis and design; (ii) knowledge based application modeling, by means of a powerful conceptual language (TQL++); (iii) advanced search techniques in the problem solving component; (iv) fast prototyping by automatic generation of executable code; (v) use of an advanced knowledge based modeling and prototyping environment (Mosaico). The paper starts with a description of the railway traffic control problem, then it focuses no the architecture of MINT, with a particular attention to the database component and its train conflict solving capabilities.
