This paper proposes see how the new technologies related to the concept of smart grids can influence on the current technological model of power transmission infrastructure in NAFTA. The comparative analysis of energy integration and smart grid technologies applied in bloc countries show that: for over four decades began on robust initiatives for cross-border electricity interconnection in North America,...
Within the last 30 years, the European Union has seen a constant increase of freight transportation due to economic growth, change in intercontinental trade and decrease of barriers within the continent. The transport system is struggling in following this trend, showing signs of inefficiency from a socioeconomic point of view. Intermodal transport represents an excellent solution able to support...
Ecology and resource efficiency have achieved high relevance in industry, not only due to their economic effects. Thus, logistics planning is required to contribute to “green” initiatives. However, it still lacks appropriate methods and tools. Simulation represents a well-accepted method in logistics planning, for it can handle dynamics, stochastic effects and a high degree of complexity. In the context...
We present an energy market equilibrium model that captures climate aspects, infrastructure constraints, fuel substitution, and market power ala Cournot in a single framework. The model represents the supply and transportation infrastructure, fuel transformation, power generation, and several demand sectors of fossil fuels, renewables and nuclear energy. We calibrate the model to market data from...
In this paper a system about a vendor and a distribution center optimizes. Classical inventory management is provided, which the transportation cost isn't considered. We integrate transportation cost into inventory management and develop optimal solution procedures.
Ridesharing is attracting more and more attention due to its high potential for applying new business models to private transportation in urban areas, reducing the greenhouse gas emissions and decreasing the amount of traffic on the streets. The paper extends the earlier presented approaches of building sustainable logistics system that support ridesharing by applying to it principles of smart spaces,...
According to characteristics of mixed vehicle routing problem with backhauls, a mathematical model is constructed. An Adaptive Memory Programming Algorithm is proposed to solve this problem. Experiments are done and analyzed to prove the rationality of the model and effectiveness of the given algorithm.
The Analytic Hierarchy Process is a proven and widely applied Multiple Criteria Decision Making method. In this paper we described an application of this approach to the problem of supplier selection in municipal bus transport company. The set of evaluation criteria included both quantitative and qualitative data bounded with financial, technical and political expectations. We investigated requirements...
Two-echelon inventory system includes a center depot (CD) and many sub depots (SD). There is little literature studying on the correlated demand which is the fundamental relationship between the CD and the SD. According to the idea of maximum part-period gain (MPG) in the operation management, the system optimal inventory strategy can be obtained through the trade-off between the order cost and the...
Globalization has prompted manufacturing firms to come to terms with environmental legislation and regulations, resulting in the manufacturing industry realizing the importance of adopting environmental friendly supply chain management (SCM) practices. A growing number of companies have realized that attaining effective SCM is only one side of the coin. The other side is to make SCM environmentally...
A Free Trade Zone (FTZ) is an economic zone that an international business can utilize to optimize its supply network. It provides the advantages of operation efficiency as well as financial benefits. For these reasons, many international businesses choose to locate their manufacturing factories or distribution centers in an FTZ. However, the deployment of business sites in such an area necessitates...
Supply chain management has no doubt become companies' strategy to enhance their competitiveness. Companies have made great efforts to redesign and reengineer their supply chains in order to improve their supply chain performance. Distribution network is a key driver of the overall profitability of a firm because it directly impacts both the supply chain cost and the customer experience. Good distribution...
In this paper, based on relevant assumptions, the maximum profit function (MPF) among different code sharing options has been established , in which the optimum fare can be gained to calculate the airlines maximum profit. Then the results would be tested by the air passengerspsila welfare function. Finally, the method is applied in practice successfully.
