Previous research on the joint economic lot size (JELS) problem was focused on the decisions of lot sizes and batches delivered among players in the supply chain, assuming that transportation cost was independent of shipment amounts. Nevertheless, the transportation cost accounts for a major part of supply chain cost, especially when transportation companies offer freight rate discount schedule...

Businesses involved in logistics and supply chain management rely on information technology to deliver services "on time" with highest productivity. One such business began in 1971 as a single-service trucking company known as O-J Transport. It later expanded its capabilities and diversified its mission to become The O-J Group, a multiservice transportation and logistics enterprise. Strategical...

This paper investigates the impact of provided service by the retailers and manufacturers on customers’ demand and members’ profit in a supply chain. It focuses on a supply chain structure with one manufacturer and a common retailer. The demand of customers depends on retailer price and service level. A game-theoretic framework is applied to obtain the equilibrium solutions for each entity in s...

One way to hedge against random fluctuations of demand in supply chains is to keep inventories at various points in the chain. Another is to actually modify the leadtimes in the system dynamically. Working with multiple suppliers, using multiple transportation options, having the option to expedite certain processes, or having different possible routes for a unit to go through the supply chain ...

The supply chain under consideration is a two-echelon system consisting of a retailer and a manufacturer. The N different products face stochastic demand at the retailer and are produced using a shared facility at the manufacturer. Production changeover involves setup time that is significantly higher than the processing time. A cyclic polling model with exhaustive limited service policy from t...

In many multi-stage manufacturing supply chains, transportation related costs are a significant portion of final product costs. It is often crucial for successful decision making approaches in multistage manufacturing supply chains to explicitly account for non-linear transportation costs. In this article, we have explored this problem by considering a Two-Stage Production-Transportation (TSPT)...

The globalization of production and service enterprises increased the complexity of supply chain systems and processes. The complexity of supply problems leaded to the development of new shipment strategies. The optimal design of supply chain is an important success factor of the economical operation of enterprises. Within the frame of this paper the author compare the costs of the direct shipm...

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...
