Abstract

THE PRODUCTION PLANNING PROBLEMS ENCOUNTERED IN REAL- LIFE SITUATIONS ARE GENERALLY INTRACTABLE DUE TO A NUMBER OF PRACTICAL CONSTRAINTS. THE DECISION MAKER HAS TO FIND A GOOD FEASIBLE SOLUTION IN A REASONABLE EXECUTION TIME RATHER THAN AN OPTIMAL ONE. THE OBJECTIVE IS TO SATISFY THE REQUIREMENTS IN THE PRODUCTION PLAN WITH MINIMUM COSTS OVER A MULTI-PERIOD PLANNING HORIZON. THIS PAPER PROPOSES A NEW MIXED INTEGER PROGRAMMING MODEL FOR MULTI-ITEM CAPACITATED LOT-SIZING PROBLEM WITH SETUP TIMES, SAFETY STOCK AND DEMAND SHORTAGES. THE PROBLEM IS NP-HARD AND TO SOLVE IT, A HARMONY SEARCH (HS) APPROACH IS USED. TO VERIFY AND VALIDATE THE EFFICIENCY OF THE HS ALGORITHM, THE RESULTS ARE COMPARED WITH THOSE OF THE LINGO 8 SOFTWARE. RESULTS SUGGEST THAT THE HS ALGORITHM HAVE GOOD ABILITY OF SOLVING THE PROBLEM, ESPECIALLY IN THE CASE OF LARGE AND MEDIUM-SIZED PROBLEMS FOR WHICH LINGO 8 CANNOT PRODUCE SOLUTIONS.
