Associate Professor
Dr. Enns' research activities lie in the general area of management and modelling of manufacturing systems. His research interests broadly fall into the following three areas:
1. Production Planning and Control Systems. Research interests are primarily related to improving job shop and batch production performance. Investigations into planned lead time setting and lot-sizing within systems using Materials Requirement Planning (DRP) logic are of special interest. Research test beds, based on simulation and queueing relationships, have been developed to address related issues.
2. Supply Chain Management. Recent activity has involved modelling material and information flow within supply chains. A test bed has been developed to investigate the behaviour of systems using centralized versus decentralized planning and control. Distribution Requirements Planning (DRP), Order Point and Kanban systems are being compared within supply chain networks.
3. Competitive Manufacturing. Interests include manufacturing strategy and quality management. A recent project has been initiated to explore competitive issues using rapid modelling relationships. Decision makers respond to a dynamically changing production environment by changing model inputs, thereby trying to maximize performance.
