Probabilistic analyses and algorithms for three-level distribution systems

Article Abstract:

A study was conducted to analyze the problem of combining inventory control and vehicle routing into a cost-effect scheme for a distribution system characterized by a single outside vendor, several retailers who are geographically dispersed and a fixed number of warehouses. Computations were carried out on a heuristic policy using random generated problems. A Zero-Inventory Ordering policy was then determined for a three-level distribution model supporting long-run average cost that converged with the cost of the lower bound. Results indicated that warehouses function as a coordinator of the frequency, time and sizes of delivers to retailers. Findings also showed that the effectiveness of a cross-docking strategy correlated with the large number of retailers.

The effects of selling packaged goods on inventory decisions

Article Abstract:

A model depicting the effect of selling packaged goods on inventory decisions reveal useful insights on developing effective inventory policies for retailers that sell products both as independent items and as part of multiproduct packets or bundles. The practice is known to improve customer satisfaction and increase the retailer's profit by spurring demand substitution between the individual product and the bundle in stockout situations. However, the model suggests that marketing and manufacturing decisions should be coordinated if profitability is to be optimized. Inventory management, should take into account the demand substitution structure and demand correlation while considering the appropriate design of multiproduct packets.

Inventory rationing in a make-to-stock production system with several demand classes and lost sales

Article Abstract:

The author examines a single item make-to-stock production system with a stock rationing problem. Optimal rationing with a first-come first-serve policy is compared with stock rationing benefits.
