According to the complex plane regions in which there are discontinuous faces and multi-connected regions caused by various materials, faultages, cracks, holes or excavated regions, an algorithm of auto-arrangement of discrete nodes and its optimization are presented in this paper.

The paper introduces the advantage、principle and constitute of the automatic cloth inspection system,discusses the pivotal technology,and analyzes the real example.

Reconstruction of automatic distributing system for shaft furnace pellets in Daye Iron Ore Mine;

To solve the problem,the interval algorithm was used to modify the load uncertainty,the mathematic model of distribution network planning,and the initialization searching method of automatic routing.

It includes three parts: automatic routing, channel expansion and routing improvement.

The very important aspect in military communications command is the large number of communications organizational charts mapping,currently,using computer software for digital mapping is in the process of research and development,the difficulties with the focus is automatic routing algorithm design and implementation.

NET,and the fulfilment process of automatic publishing the GIS graphic data to production control web are presented.
