We consider an EOQ model in which the content level is modelled by a Brownian Motion (BM) with state-dependent drift and diffusion parameters. There are either one or two prespecified switchover threshold values (cases 1 and 2) such that th...
We consider multi-period one-dimension assortment problems in which demands for all sizes meet the conditions for a dynamic demand economic lot size problem, the same set of sizes are stocked and the same substitution rules are followed in ...
We extend well-known formulae for the optimal base stock of the inventory system with continuous review and constant lead time to the case with periodic review and stochastic, sequential lead times. Our extension uses the notion of the |ext...
This study investigates how different supply chain policies and different operating environments affect schedule instability in a supply chain. Experimental study on a simple supply chain system consisting of a buyer and a supplier is condu...
Classical multi-echelon repairable item inventory models are based either on steady-state analysis or infinite repair capacity, which may not work well in situations when the demand is nonstationary, or repair capacity is limited. In this p...
