This subject is one which forms part of a production planning and control system. Such a system in a manufacturing business, e.g. engineering, becomes extremely complex, involving as it does the breakdown from sales order requirements to the basic factors of men, machines, parts and raw materials, followed by the scheduling of the work-load on to the plant and the consequential feedback control loop to check on results and modify future plans. An essential factor in all such systems is time because the system is a dynamic one, subject to constant change It follows therefore that the smaller the time-lag which elapses between the preparation of the plan and its communication to the factory floor, the greater will be the likelihood of the plan being achieved. The following case study does not attempt to cover such a complex system, but it is hoped that the importance of speed of processing will become obvious to the reader.
