in the current seismic data acquisition techniques, sources are fired with large time intervals in order to avoid interferences between the responses of successively firing sources, measured by the receivers. this leads to a time-consuming and expensive survey. theoretically the waiting time between two successively firing sources has to be infinite, since the wavefield never vanishes completel...

Due to globalization, logistics has become an important part in the supply chain. Many logistics service providers have realised the importance of adoption of technologies that can help manufacturers, warehouses, and retailers to communicate with each other more efficiently. Among many logistics technologies, Radio frequency identification (RFID) has been identified as an important technology t...

Based on analyzing the difficulties of reverse logistics operation management and discussed the new environment as the economic society developing continuously and discussing the feasibility of virtual enterprise, an operation management mode for reverse logistics based on virtual enterprise is presented in this paper. By analyzing the relationships between complaint service management and reve...

Recently sensor technology has drawn greater attention in ubiquitous computing by deploying huge amount of sensor tags in supply chain, harbor logistics, healthcare management etc. Sensor tags are capable to provide the sensing information of the product and item with its identification at the same time. The dual data generated from a sensor tag is RFID data and Sensing data. RFID Readers are u...

This paper proposes a new model of simultaneous optimization of three-level logistics decisions, for logistics authorities, logistics operators, and logistics users, for regional logistics network with environmental impact consideration. The proposed model addresses the interaction among the three logistics players in a complete competitive logistics service market with CO2 emission charges. We...

With development of technology and science and continuous increase in productivity, product life cycles are shortened and customer demands are more personalized and diversified, which makes companies face with ever changing and unpredictable competitive environment. Therefore, rapid response to market competition has become one of the main focuses and the competitive advantages. Today, one of t...

E-commerce is a complete process that consists of information flow, capital flow, business flow, and logistics. With the development of network and electronic technology, the information flow, capital flow, and business flow can be momentarily available through computer and network communication equipment. The logistics that must be achieved in reality become a key part in influencing the effic...

Introduction A recent innovation in support of the final segment of the immunization supply chain is licensing certain vaccines for use in a controlled temperature chain (CTC), which allows excursions into ambient temperatures up to 40°C for a specific number of days immediately prior to administration. However, limited evidence exists on CTC economics to inform investments for labeling other e...
