A key decision for every product consolidation node (e.g. warehouse or cross-dock) in a distribution network is the synchronization of inbound and outbound product flows. Among other operational issues, the physical space restrictions as well as the restricted availability of resources (e.g. forklifts) limit the number of vehicles that can be proce...

This paper presents a new generalized vehicle routing problem with a cross-dock. Basic features of the examined problem are the many-to-many relationship between the suppliers and customers, and the use of different vehicle fleets for performing the inbound and outbound routes. An adaptive memory programming method has been developed coupled with a...

This work considers the problem of satisfying transportation requests from a set of suppliers to a set of customers. Each request calls for moving products between a pick-up and a delivery location pair. A commonly adopted approach is the direct-shipping of products, without using intermediate transshipment points, or in-transit merge of shipments....

In this work, we propose a hybrid simulation optimization approach that addresses the problem of supply chain management. We formulated the problem as a mathematical model which minimizes the summation of production cost, transportation cost, inventory holding and shortage costs, subject to capacity and inventory balance constraints and propose a h...

The importance of balancing social, environmental and economic objectives in companies’ development has cultivated a growing awareness on the sustainable optimal design and planning of supply chains. In the past years, significant research effort has been devoted to extend current approaches to capture these objectives in order to guarantee long te...

In an increasingly competitive and complex business environment, Supply Chain Management (SCM) has emerged as a practice for improving the overall performance of companies. In recent years, strategies for SCM have been broadened to integrate operation planning and scheduling. Efficient implementation of such strategies for minimizing total cost and...
