We propose a new formulation for controlling inventory in a two-echelon distribution system consisting of one warehouse and multiple non-identical retailers. ...
In such a system, customer demand occurs based on a normal distribution at the retailers and propagates backward through the system. ...

Abstract: This paper presents solution procedures for determining close-to-optimal stocking policies in a multi-item two-echelon spare parts inventory system. ...
The system we consider consists of a central warehouse and a number of local warehouses, and there is a target for the aggregate mean waiting time per local warehouse. ...
This model considers multi-item inventory systems with which repair and distribution processes are controlled in a two-echelon system, consisting of a central warehouse and a number of local warehouses ...

Lateral transshipments within an inventory system are stock movements between locations of the same echelon. ...
These transshipments can be conducted periodically at predetermined points in time to proactively redistribute stock, or they can be used reactively as a method of meeting demand which cannot be satisfied ...
Two echelon centralized systems In a system with two echelons there are several ways in which stockouts can be satisfied through emergency stock movements. ...
