Computing base-stock levels for a two-stage supply chain with uncertain supply
Omega, 89, 92–109.
Contributors: n , W. Wangwatcharakul* & R. King n
author keywords: Inventory; Base-stock system; Uncertain supply
TL;DR:
This work uses a recently published computational algorithm to generate independent, single-stage (ISS) base-stock inventory solutions for each stage in a two-stage supply chain subject to uncertainty in upstream supply, and finds that the downstream stocking levels are strongly influenced by the properties of the downstream demand, while the upstream stocking level is very strongly influences by the holding costs and supply uncertainty.

A recursive expression for the steady-state probability vector of a discrete-time Markov process (DTMP) model of this imperfect-supply inventory system is developed and used to prove the convexity of the inventory system objective function, and the optimality of the computational procedure for finding the optimal base-stock level is proved.

The Impact of Revenue-Maximizing Priority Pricing on Customer Delay Costs
DECISION SCIENCES, 40(1), 89–120.
author keywords: Priority Pricing; Queueing Theory; and Supplier-Customer Relationships
TL;DR:
The customers are better off collectively when the supplier and customers act independently in their own best interests, and as the number of priority classes increases, both the priority revenues and the overall customer delay costs improve, but at a decreasing rate.
