Abstract

Relatively little attention has been given to methods for estimating and auditing distribution network inventories in the aggregate. This article shows a polynomial equation of the form I_T = Σ(w+mD_i+aD_i^b) which has theoretical verification is a good, basic tool for estimating overall inventory levels as well as providing insight into the effectiveness of inventory control policies at different stocking points. It also serves as a method for auditing and controlling current inventory policies on an on-going basis. Testing the model in a number of cases where "pull" distribution strategies were in effect revealed that good inventory policy could be represented by I_T = K)D_i^b where b ranges between 0.65 and 0.75.
