Orders Loading and Release in Flow Shops including Outsourcing Networks

January 2006IFIP International Federation for Information Processing 257:75-92
Purpose of this paper is to analyse and compare the behavior of workload control models in flow shops of both the MTO (Make-To-Order) and MTS (Make-To-Stock) classes. A simulation model has been built, where a manufacturing cell is loaded through an input control mechanism with shop orders coming from a pool. The pool itself is fed with planned orders coming from an MRP system.
