In this work, the design and operation planning of a multi-period, multi-product closed-loop supply chain is addressed. Recovered end-of-life products from customers are evaluated in disassembly centers and accordingly are sent back to factories for remanufacturing, or leave the network either by…

In this setting, sustainability at the supply chain level is…

This work analyses partial information sharing involving retailers with different operational configurations. Retailers are characterized by four operational factors, i.e., demand variance, lead time average, forecasting period and inventory policy. The findings show that the performance…

Sustainable Supply Chain have become a cornerstone to any company that seeks to achieve sustainable goals. A company’s image is no longer related to the old paradigm of being sustainable in its own activities, but instead is associated with a strong collaboration between all supply chain…

This paper analyses the impact on supply chain performance of adopting different strategies to implement partial information sharing among heterogeneous retailers. Supply chains are modelled using a multi-agent systems approach. We find that the strategy adopted to construct the partial…

Increased pressures from stakeholders have been forcing companies to integrate social sustainability into their businesses. However, lack of information leads to gaps in social sustainability, some of them being also related to difficulties in social sustainability assessment of supply chains often caused by…

A large number of problems in a distribution supply chain require that decisions are made in the presence of the bullwhip effect phenomenon. The impact of the order batching policies on the bullwhip effect is analysed in this paper, when cycle demand on a multi-echelon supply chain operating is…

Supply chains are changing their business paradigm as they strive for sustainability and not just for increasing profits. Sustainability, however, is a concept that is open to interpretation since it is based on societal and organizational values. Little is known about what companies actually mean when…

This paper analyzes how order batching policies impact on the bullwhip effect over a multi-echelon distribution supply chain facing cyclic demand. As a demand cycle is repeated over the time planning horizon, a wrapping around operator is considered and based on this a single cycle is required to…

In this paper, a mixed integer linear programming (MILP) formulation is proposed that integrates financial risk measures into the design and planning of closed-loop supply chains, considering demand uncertainty of final products. The goal is to maximize the supply chain expected net present value…

This paper considers a multi-echelon inventory/distribution system formed by N-warehouses and M-retailers that manages a set of diverse products in a dynamic environment. Transshipment at both regional warehouses and retailers levels is allowed. A mixed integer linear programming model is…

The design and planning of resilient supply chains is a major challenge due to the increasing complexity of these systems that operate in a global market and therefore are more exposed to disruptions. In the present work a design and planning model that integrates demand uncertainty is…

The goal of this paper is to quantify the impact of Inventory Record Inaccuracy on the dynamics of collaborative supply chains, both in terms of operational performance (i.e. order and inventory stability), and customer service level. To do so, we model an Information Exchange Supply Chain…
