At present, with the rapid development of manufacturing industry, the problem in the production process is constantly exposed. This kind of production system is very complicated that it is often the spatial variable, time variable and random variable interdependent dynamic problems. The computer simulation software is the one of the best effective way to find out the problems existing in the production process. This paper takes one product line as example, using Flexsim simulation software in the production line for modeling and simulation. Then the simulation test and simulation analysis is done to find out the bottleneck of the system. Finally proposal is given to solving the bottleneck problem, and Flexsim simulation of new distribution is proved that it could improve the efficiency of the production line.

Urbanization construction requirements of smart grid,and distribution automation is the foundation of smart grid.Because of its own characteristics of the rural power grid, the construction of distribution network is not the same of city construction. This paper from the rural development trend and its characteristics, analysis of the function of rural distribution automation system, and put forward the suitable for rural distribution automation mode from the aspects of main station system,substation,distribution terminal,communication system and feeder automation of several.
