The paper builds up the structure model of logistics quality chain, analyzes the possible risk, establishes the index system of logistics quality chain risk and gives out the fuzzy hierarchy analytic method for the risk.

The development direction of optimizing interface integrating technology of BF/BOF route was investigated by analyzing the production organization parameters, the mass flow-rate, time and temperature of BF/BOF route at Shagang, and the features of the multi-dimensional mass flow control with one open ladle from BF to BOF were studied.

The logistics quality connotation and its particularity are analyzed,and the quality of logistics corporations should be measured mainly in terms of logistics time,logistics cost,and logistics efficiency.

The equations of critical velocity are derived for horizontal pneumatic transport under three constraint conditions(the mass flux of solid and the pipe diameter,the mass flux of solid and the mass flow ratio of solid to gas,the mass flow ratio of solid to gas and the pipe diameter are respectively set to be constant).

A Study on Logistics Service Quality and Its Relationship with Customer Loyalty of B2C Internet Store;

Methods of logistics service quality are reviewed at first.

It is necessary for logistics enterprises to establish an effective system of logistics service quality based on customer value.

Although the logistics market has been started in China, attributing to the insufficient logistics demand, especially the low logistics demand quality, it has not yet been activated.
