-The selection of third party logistics (TPL) providers is an important issue for enterprises to outsource their logistics business. In this paper we propose a comprehensive evaluation model for TPL suppliers based on AHP method. Furthermore, we Base on the evaluation index system including logistics cost, the logistics operation efficiency and the basic qualities of service. The efficiency and...

The structure of the construction project logistics system is decomposed in detail; some uncertain factors affecting system reliability are analyzed. This paper applies the probabilityinfluence coordinate graph to screen out the logistics subsystem that has great influence on system reliability under the conditions of occurring failure, and establishes an allocation model of the reliability ind...

The circulation of agricultural products is more complex and uncertainty than that of industrial products. The distribution channels of agricultural products are quite unique. The agricultural products logistics directly affect the efficiency of china’s economy since agriculture is still main part of the economy. At the same time, with the development of information technology, e-business has a...

Logistics runs through the entire process of an enterprise’s production and management. Logistics, as an enterprise’s "the third profit source", is an effective management tools for companies to obtain and maintain a competitive advantage, the management of logistics risk of marketing channels is a critical part of the risk management of channels. The paper introduces the logistics risk types, ...

The contradiction between economic development and environmental deterioration makes people begin to have a further understanding of the ecology and environment. To promote effective development of reverse logistics and implementation, according to general activity process of manufacturing enterprises, this paper builds the manufacturing system model of reverse logistics. On the basis of activi...

Apomorphine, a nonselective dopamine receptor agonist, facilitates penile erection and is effective in patients suffering from erectile dysfunction. The specific dopamine receptor subtype(s) responsible for its erectogenic effect is not known. Here we report that the dopamine D(4) receptor plays a role in the regulation of penile function. ABT-724 is a selective dopamine D(4) receptor agonist t...

Traditionally, logistics analysis for space missions has focused on the delivery of elements and goods to a destination. This type of logistics analysis can be referred to as “macro-logistics”. While the delivery of goods is a critical component of mission analysis, it captures only a portion of the constraints that logistics planning may impose on a mission scenario. The other component of log...

The economy, which has become more information intensive, more global and more technologically dependent, is undergoing dramatic changes. The role of logistics is also becoming more and more important. In logistics, the objective of service providers is to fulfill all customers’ demands while adapting to the dynamic changes of logistics networks so as to achieve a higher degree of customer sati...

This paper describes the use of a formal approach to logistics management systems to reduce the environmental impact of logistics operations. Trucks play an essential role as carriers in modern logistics services, but collectively they emit a huge quantity of carbon dioxide. To reduce fossil fuel consumption and carbon dioxide emissions resulting from transport, we must enhance the transport ef...

This study extends Vidal & Goetschalckx’s [19] model, emphasizing on how to add concerns of uncertainties on all players in a global logistics system appropriately. By addressing the tradeoffs between overall system reliability and total cost of a global logistics system, an extension model with two operation modes are proposed. Mode 1 operation aims to seek minimum cost on a target of system r...
