We develop a deterministic optimization model that incorporates carbon emissions in a multi-echelon production-inventory model with lead time constraints. We impose that each customer order must be delivered within the due date fixed by the customer. The quantity that cannot be delivered on time...

In this paper, we propose a mathematical model for the design of supply chains in the delocalization context. Our main objective is to develop a strategic-tactical supply chain design model that integrates all the relevant components that characterize the delocalization problem. We adopt the...

This paper presents the important factors that should be considered in the design of supply chains in the delocalization context. The methodology adopted in this work consists firstly in determining the characteristics of the delocalization problem by proposing an appropriate definition of the...

Suppliers network in the global context under price discounts and uncertain fluctuations of currency exchange rates have become critical in today’s world economy. We study the problem of suppliers’ selection in the presence of uncertain fluctuations of currency exchange rates and price...

In this work, we show that the optimization models for manufacturing systems should evolve to consider the environmental impacts of manufacturing activities and to integrate the environmental performance of finished products. In particular, the selection of manufacturing processes (technologies)...

We consider two reverse logistics systems where returned products are as good as new. For the first system, the product return flow is independent of the demand flow. We prove that the optimal policy is of base-stock type and we establish monotonicity results for the optimal base-stock levels,...
