Comparison of echelon stock and installation stock policies for two-level inventory systems

Article Abstract:

Analysis of two-level inventory systems using worst-case scenarios is undertaken to determine the relative merits of echelon stock policies and installation stock reorder point policies. Added assumptions in the scenario are constant demand level and the absence of backorders. Using stochastic simulation methods, it is shown that echelon stock policies are preferred in cases characterized by long warehouse leads and vice versa.

A joint replenishment policy for multi-echelon inventory control

Article Abstract:

A study was conducted to analyze a two-level inventory system supporting a central warehouse and a number of identical retailers. The retailers face stationary and independent Poisson demand while the warehouse utilized a regular installation stock batch-ordering policy. In addition, the costs were evaluated while the policy was compared to an installation stock and to an echelon stock policy.

Comparison of echelon stock and installation stock policies with policy adjusted order quantities

Article Abstract:

The analogy of echelon stock and installation policies with policy arranged order quantities showed that echelon stock policies lead installation stock policies for serial and assembly systems. It is clear that the disadvantages connected with an installation stock policy are more minor when the order quantities can be conformed to the policy.
