Distribution network design as a strategic decision has long-term effect on tactical and operational supply chain management. In this research, a supply chain design problem based on a two level capacity location allocation problem (TLCLAP) is presented. A product must be transported from a set of seaport to meet stores demands, passing out by intermediate warehouses. The objective is to locate...

In this study, a two echelons supply chain system in which a supplier is producing perishable product and distribute it to multiple customers is considered. By allowing lateral transshipment mechanism, it is also possible to deliver products to some customers in some periods in bulk, then customers using their own vehicle to transship goods between each other seeking further reduction in the ov...

In any supply chain, distribution planning of products is of great importance to managers. With effective and flexible distribution planning, mangers can increase the efficiency of time, place, and delivery utility of whole supply chain. In this paper, inventory routing problem (IRP) is applied to distribution planning of perishable products in a supply chain. The studied supply chain is compos...

a comprehensive and integrated study of any supply chain (sc) environment is a vital requirement that can create various advantages for the sc owners. this consideration causes productive managing of the sc through its whole wide components from upstream suppliers to downstream retailers and customers.  on this issue, despite many valuable studies reported in the current literature, considerabl...

Abstract: Due to the energy savings and environmental protection they provide, plug-in electric vehicles (PEVs) are increasing in number quickly. Rapid development of PEVs brings new opportunities and challenges to the electricity distribution network’s dispatching. A high number of uncoordinated charging PEVs has significant negative impacts on the secure and economic operation of a distributi...

Critical infrastructure resilience has become a national priority for the U.S. Department of Homeland Security. Rapid and efficient restoration of service in damaged transportation networks is a key area of focus. The intent of this paper is to formulate a bi-level optimization model for network recovery and to demonstrate a solution approach for that optimization model. The lower-level problem...

Maximizing the potential value of demand-side resources in terms network reliability and economy is a considerable challenge because their time-varying potentially complex operational characteristics. It urgent to take interactive relationship between supply demand side into consideration improve efficiency practicability distribution planning enhance utilization existing equipment. In this pap...

In this paper, parameters choices of simulated annealing for continuous network design problems are discussed. A bi-level programming model for continuous network design problem is introduced. Objective function of the upper level is defined as the sum of the total travel time on the network and the total investment costs of link capacity expansions. The lower level problem is the user equilibr...
