Greg Siemon is currently undertaking a Steel Research Hub sponsored PhD, hosted by the School of Chemical Engineering at the University of Queensland. His topic is Enterprise-Wide Optimisation. Enterprise-Wide Optimization (EWO) is a new emerging area that lies at the interface of chemical engineering and operations research, and has become a major goal in the process industries due to the increasing pressures for remaining competitive in the global marketplace. EWO involves optimizing the operations of R&D, supply, manufacturing and distribution of a company to reduce costs and inventories. A major focus in EWO is the optimal operation of manufacturing facilities, which often requires the use of nonlinear process models. Major operational items include planning, scheduling, real-time optimization and inventory control. One of the key features in EWO is integration of the information and decision-making among the various functions that comprise the supply chain of the company. Within his PhD Greg will be working with Bluescope to improve the operation of their steel smelter at Port Kembla, in the Illawarra. The Coal Seam Gas industry in Central Queensland is another potential area for investigation.
