As early as the mid 1960's the production and scheduling systems at the Port Talbot and Llanwern sites of British Steel were computerised. This involved real-time shop floor data collection systems enabling material tracking and stock/order analysis. All orders were handled by computer systems. This enabled the scheduling sections to plan and schedule orders through the various processes aiming to meet delivery promises and control stocks. Each item of plant was scheduled individually, supplying adequate stock for the next process. Also, the planning and scheduling systems for Port Talbot were different and separate to Llanwern. In January 1995 work started on enhancing both works' planning and scheduling systems leading towards one common system. Initially the planning systems were developed to each site followed by the new scheduling systems. The most fundamental difference in the new system is that it plans the production activities for the whole plant, rather than just the individual units. This thesis describes the old planning and scheduling systems within Port Talbot and Llanwern Works and the difficulties associated with the old, manual methods used for scheduling the production units, particularly the steelmaking/continuous casting plant and the hot strip mills. Descriptions of the newly adopted systems are given with details of the implementations, plus information on the problems encountered. Associated systems are also described, in particular the manufacturing execution system (MES) and the plans for replacing it with a new system. There is also a comprehensive review of the literature pertaining to planning and scheduling in the metals, and more specifically, the steel industry.
