Optimal Inventory Policies for Remanufacturing Systems that Forecast Product Returns
In this presentation, we consider an inventory system with remanufacturing capability to remanufacture two types of cores: buyback and returned cores, and that is able to forecast product returns. We present a backlog model for the system. The returns forecast for returned cores is modelled explicitly to depend on past demands. We arrive at a simple optimal remanufacturing and disposal policy, and obtain results that show how the optimal policy changes with change in returns forecast due to change in past demands. We also study numerically the effect the dependency of returns on past demands has on optimal cost.
Biography: Dr Sim is a lecturer with the Department of Mathematics, University of Portsmouth. He joined the department recently. He obtained his Ph.D., specialising in optimisation, in 2005 from the National University of Singapore, and his M.Sc., specialising in optimisation, in 1997 from the University of Washington, Seattle. He has been with the National University of Singapore and The Hong Kong Polytechnic University for a number of years before joining the department. Dr Sim’s research interests includes semi-definite programming: theory and applications, supply chain management and subgradient methods. He has publications in Mathematical Programming, SIAM Journal on Optimization, European Journal of Operational Research, among others.
