Research

Research interests

Professor Disney’s research interests involve the application of control theory and statistical techniques to operations management and supply chain scenarios to investigate their dynamic, stochastic, and economic performance. Stephen has a particular interest in the bullwhip effect, forecasting, and inventory management. Stephen has advised several of the world’s largest corporations on the bullwhip effect and his research has influenced the material flow of at least 1 in every 7 pounds of UK retail sales. He has worked with many companies in the UK, US, and Europe and on supply chains that operate globally.

Stephen is interested in supervising PhD students in the areas outlined above and also topics on supply chain collaboration, MRP nervousness, global dual sourcing, the dynamics of closed-loop supply chains, integer demand, and non-linear supply chain models.

Stephen is currently the Director of the Computer Simulation and Analytical Modelling research center within the Business School.

Research projects

Stephen is currently exploring the dynamics of global dual sourcing supply chains. He is also writing a book entitled “Setting the cadence of your pacemaker: A lean workbook for reducing your Mura and Muri”.
