WHAT HAVE BEEN DEVELOPED FOR LOT-SIZING AND SCHEDULING PROBLEM SINCE THE EOQ MODEL WAS INTRODUCED (original) (raw)

The paper is devoted to the selected heuristics for lot-sizing and scheduling problem for identical parallel machines. The lot-sizing and scheduling problem is a well-known problem in industrial engineering and logistics management, since it is crucial for inventory control and production planning. In 1913 the Economic Order Quantity(EOQ) concept was presented and the EOQ model was developed – it was a very useful tool for production and purchase planning, however, it simplified the reality significantly. Over the last century lot-sizing and scheduling problem was examined and numerous more advanced models, which consider multiple aspects of manufacturing process, were developed. In this paper a review of approaches to lot-sizing and scheduling problem are reviewed from the perspective of specific goals adopted, models developed for the problem, and methods used for solving them.
