The proposed material handling system is automatic guided vehicle (AGV).
(ii) Material handling system must by bidirectional.
Sometimes the reconfiguration requirement to perfectly accommodate production of a new product is just a change in the direction of the material handling system or in some other instances, an aid to easy reconfiguration.
There are many theories in social sciences towards solving the problem, but nearly all of them will still come down to affecting the manufacturing system.

Integrated automation monitoring system in the application of 220kV substation Yan Yan1, Xinghua Ma2 Feifei Ji3 12 College of Sciences, Hebei United University, Tangshan, Hebei, China 3 College of Mining Engineering, Hebei United University, Tangshan, Hebei, China yanjxky@126.com Keywords: Substation, monitoring system, integrated automation control system Abstract.
This itself is a enormous waste of human and material resources, when debugging the same work twice must be done twice, but also is unlikely to ensure both identical, and meanwhile bring contradictory to the protection.
Conclusion In view of the substation automation system in the next stage is also a lack of a unified national standard, This requires in the actual operation constantly summarize experience, and find the regularity, Do not follow the beaten track, And because under the circumstances, we should follow the spirit of science to build the substation automation system To ensure the power safety and economy, high-quality operation.

The castable refractories discussed here are that using alumina cement as the bonding agent [2] The ultrasonic velocity of the shear and longitudinal waves in an isotropic material, linearly elastic bulk solid are related to the density and the elastic moduli [3].
The accurate measurement of the velocity of this signal can be effectively used to evaluate many parameters of the material and to detect flaws in test pieces.
