Analysis of the effect of various unit costs on the optimal incoming quantity in a perishable inventory model

Article Abstract:

A perishable inventory model is used to examine the effect of four unit costs: ordering, holding, shortage and outdating costs, on the optimal incoming quantity for the case of one lead-time. The ordering, the holding, and the outdating costs have an inverse relationship with the optimal incoming quantity, whereas the shortage cost has a direct relationship with the optimal incoming quantity.

Two-warehouse inventory models for deteriorating items with shortages under inflation

Article Abstract:

The two-warehouse inventory problem for deteriorating items with constant demand rate and shortages under inflation is discussed. The comparison of the two two-warehouse inventory models shows that the proposed model is less expensive to operate than the traditional one if the inflation rate is greater than zero.

Decentralized inventory control in a two-level distribution system

Article Abstract:

Research is presented concerning the development of a model which can be used with a two-level distribution system for inventory control which is decentralized. Cost-structuring and batch-ordering are discussed.
