Designing Activity-Based Supply Chain Networks under Uncertainty
An approach to design supply chain networks operating under uncertainty is presented. A
stochastic programming model based on activity graphs, resource acquisition and deployment
options is first formulated. A Collaborating Agent Teams metaheuristic developed to solve the
model is then proposed. Numerical results for several test problems are finally presented.

Production Capacity and Pricing Equilibrium Strategies in a Dynamic Supply Chain
We adopt a dynamic framework to study the pricing and capacity investment decisions in a dyadic supply chain which consists of a supplier and a manufacturer governed by a wholesale price contract. An integrated supply chain assumes that there exists a centralized decision maker that fully coordinates the pricing and capacity decisions. A decentralized supply chain, on the other hand, means that the supplier and the manufacturer are involved in a noncooperative game-theoretic situation. In such a game, there are different decision rules—open-loop, closed-loop, feedback—that are available to the supply chain participants. The critical issue that we examine is to which decision rule most efficiently mitigates the double marginalization phenomenon in the context of production capacity dynamics in a supply chain composed of one manufacturer and one supplier. We develop and analyze a differential game model to examine how the supplier and the manufacturer in a decentralized supply chain determine, with the different decision rules, their production capacities and pricing policies to maximize their profits over an infinite planning horizon. We compare the production capacities and prices that develop, as well as the demand and profit for the complete channel, to that for the coordinated solution.

A Value Chain Model for End-of-Life Aircrafts
Aerospace industry is motivated to looking for best strategies to recycle end-of-life
aircrafts or re-use their components. The interests of different stakeholders and their complex relationship should be studied to ensuring that optimal operation is developed. This study provides a decision support tool for value chain analysis of end-of-life aircrafts.
