This paper considers a single-sourcing network design problem for a three-level supply chain. For the first time, a novel mathematical model is presented considering risk-pooling, the inventory existence at distribution centers (DCs) under demand uncertainty, the existence of several alternatives to transport the product between facilities, and routing of vehicles from distribution centers to c...

In many contexts, logistics is used to enable competitive advantages and cost savings. For some companies, logistics itself is its core competency (i.e. logistics providers). In this context, vendor-managed inventory (VMI) systems are one of the most up-to-date strategies allowing companies to reach a superior performance. Under a VMI strategy, the replenishment and distribution making process ...

We study a supply chain consisting of production-inventory systems at several locations which are coupled by common supplier. Demand customers arrives each production system according to Poisson process and is lost if the local inventory depleted ("lost sales"). To satisfy customer's demand server needs raw material from associated inventory. The supplier manufactures replenish inventories, con...

This study proposes the hybridization of tabu search (TS) and variable neighbourhood descent (VND) for solving Inventory Routing Problems with Stochastic Demand Time Windows (IRPSDTW). Vendor Managed (VMI) is among most used approaches managing supply chains comprising multiple stakeholders, implementing VMI require addressing Problem (IRP). Considering practical constraints related to demand u...

Abstract Maritime inventory routing problems with load-dependent speed optimization involves determining optimal routes, as well vessel speeds and loads at these so that limits are satisfied both production consumption ports. This paper considers a variant where rates can be selected from several available alternative levels, opposed to the normal situation chosen priori. In cases, remain const...

In this work, we introduce the multiscale production routing problem (MPRP), which considers the coordination of production, inventory, distribution, and routing decisions in multicommodity supply chains with complex production facilities. We propose an MILP model involving two different time grids. While a detailed mode-based production scheduling model captures all critical operational constr...
