Supply chains provide the critical infrastructure for the production and distribution of goods and services in our Network Economy and serve as the conduits for the manufacturing, transportation, and consumption of products ranging from food, clothing, automobiles, and high technology products, to even healthcare products. Cities as major population centers serve not only as the principal deman...

One of the most important issues in supply chain management, is integration of the supply chain to reduce the cost of the entire chain. In this study, a nonlinear mathematical mixed integer programming model consists of two levels of the supply chain including manufacturing plants and distribution centers have been investigated. The aim is determining orders sequencing on a single machine and a...

Recently, Northeast Asia has become one of the three largest trade areas, covering approximately 30% of the total trade volume of the world. However, the distribution facilities are saturated due to the increase in the transportation volume within the area and with the European countries. In order to accommodate the increase of the transportation volume, the transportation networking with the m...

In the last decade, we are faced with a dozen food crisis, which have impact on human health. EU as response to food contamination applies a set of laws and standards for food traceability through all stages of production, processing and distribution, forcing that all food and feed operators implement special traceability systems. One of the main and a crucial element of this system is food tra...

In this paper, developed a new multi-product, multi-period, and multi-level closed-loop green supply chain planning model under uncertain conditions. The formulated model consists of five objective functions, which minimize the cost of the supply chain, minimize the CO2 emission of transportation vehicles, maximize the reliability of manufacturing and distribution centers, maximize t...

The paper investigates whether deviations from the law of one price can attributed to real factors, such as transportation and distribution costs. Even if trade is costly, the prices of a good at different locations will be linked as long as the good is traded. Instead of the usual iceberg assumption, I model costly trade as a transportation sector that uses real resources with potentially diff...

The paper investigates whether deviations from the law of one price can attributed to real factors, such as transportation and distribution costs. Even if trade is costly, the prices of a good at di.erent locations will be linked as long as the good is traded. Instead of the usual iceberg assumption, I model costly trade as a transportation sector that uses real resources with potentially diffe...

This study examined the emissions produced during the pre-farm, farm and post-farm phases of the production cycle of raspberries and giant American whortleberries (blueberries) cultivated in one of the best-adapted areas in northern Italy. The pre-farm phase included the greenhouse gas emissions from the production of plants in the nursery and the transportation of the plants to the production ...

Nowadays, supply chain management (SCM) is an interesting problem that has attracted the attention of many researchers. Transportation network design is one of the most important fields of SCM. In this paper, a logistics network design is considered to optimize the total cost and increase the network stability and resiliency. First, a mixed integer nonlinear programming model (MINLP) is formula...

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-item economic lot-sizing model, adding stationary production capacities at the manufacturer, as well as multiple interm...
