Alexandros was a gentleman. He rescued me after my high traffic website near ground to a halt. This was due to SQL database errors and high CPU usage on server. Before I even posted a project, he had a look a fixed things. He charged me for half hour's work, but I paid him for a full hour in appreciation.

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.
