Practical Use of Operations Research for Production Planning

This paper firstly presents fundamental modelling procedures which will be employed in production planning in process industries. Secondly, various optimization problems are discussed, which arise in the hierarchical levels of production planning. Then possible operations research methods to solve them are presented. Lastly, since there exist many combinatorial optimization problems in production planning activities, practical considerations of integer programming methods are discussed. Negative aspects of practical application of integer programming are also described.
