Abstract

HELP IS AN INTERACTIVE DECISION SUPPORT SYSTEM FOR THE CHOICE OF ROUTE AND MODE FOR THE TRANSPORTATION OF AN AMOUNT OF ANY HAZARDOUS SUBSTANCE FROM A SUPPLIER TO A CUSTOMER, WITH THE CONTEXTUAL REDUCTION OF BOTH COST AND RISK TO ACCEPTABLE VALUES. THE CASE PRESENTED REFERS TO LOMBARDY, (ITALY); IT IS BASED ON A DATA-BASE OF THE ROUTE NETWORK OF THE REGION. THE SYSTEM ALLOWS FOR 9 CLASSESS OF SUBSTANCES AND 3 DIFFERENT KINDS OF TRUCK. THE SYSTEM IS BASED ON TWO DIFFERENT MODULES : THE FIRST GENERATES ALL POSSIBLE ROUTES BETWEEN THE SUPPLY POINT AND THE DESTINATION, BY THE USE OF A BRANCH AND BOUNDS ALGORITHM, ACCELERATED BY SOME HEURISTIC RULES. THE SECOND MODULE IMPLEMENTS THE DECISION, THROUGH THE CHOICE OF THE BEST AVAILABLE ALTERNATIVE WHICH IS IN AGREEMENT WITH THE INDICATIONS OF THE USERS. THIS CHOICE IS CARRIED OUT BY MEANS OF A REFERENCE POINT APPROACH : THE USER'S PREFERENCES ARE POINTED OUT BY THE INDICATION OF A POINT IN THE SPACE OF CRITERIA THAT SATISFIES HIM. THE SYSTEM THEN FINDS THE REAL ALTERNATIVE WHICH IS CLOSEST TO THIS REFERENCE POINT, AND PRESENTS IT AS A SOLUTION TO THE PROBLEM. IF THE USER DOES NOT AGREE WITH THE PROPOSED SOLUTION HE CAN CHANGE HIS PREFERENCES AND RUN THE PROBLEM AGAIN. THE SYSTEM HELP IS RUN ON A IBM PERSONAL COMPUTER AT/2 WITH 512 KBYTE MEMORY, A MATHEMATICAL COPROCESSOTEL 80287 AND AN EGA GRAPHIC CARD RUNNING THE DOS OPERATING SYSTEM.
