Event Details

Konstantina Skouri from The University of Ioannina will be speaking about Inventory Management Research.

ABSTRACT

An inventory system is studied, controlled by the periodic review base stock (S, T) policy and facing a fixed-rate deterministic demand which, if unsatisfied, is backordered. Entire supply batches may be defective and therefore rejected on arrival (i.e. the supply deliveries may fail according to a Bernoulli process). This supply setting relates with supply under random yield and supply under disruptions. The objective is the jointly determination of the two policy variables (review interval and the order-up-to level), so as to minimize long-run average cost. The cost is derived under two common accounting schemes for inventory cost evaluation: continuous and end-of-cycle costing. Exact closed-form solutions for the optimal order-up-to level S and the review interval T (for both costing schemes) are provided and their association with those of the classical EOQ (with backorders) model are discussed. Computations show the consequences of using the inaccurate end-of-cycle costing scheme or ignoring the supply process quality on the system cost performance. This presentation based on a joint work with Prof. Lagodimos and Prof. Konstantaras.
