Whether the road networks can be reliable or not depends on the following two factors: the function evaluation index of traffic system,such as connectivity reliability,travel time reliability,capacity reliability,and traffic flowing reliability,and the correct and objective analysis of their i.

This paper analyzes the concept of road network capacity reliability and introduces it into the transportation environment impacted by the route guidance system.

To decrease the amount of calculation, a bi-level programming model based on link travel time reliability was set up for road network capacity reliability through analyzing the concept of road network capacity reliability.

On-site testing shows that the quality reliability of remote monitoring indicator diagram has been improved.

In terms of strengthening people-centered reliability education, applying reliability design in product design, manufacture, and test, strengthening reliability management by establishing databanks, and introducing international standards, a brief introduction is made of the application and development of quality reliability in Ji'nan Diesel Engine Co.

Based on the characteristics of the oilfield enterprises, the necessity of applying quality reliability technology is expounded.
