ABSTRACT: The purpose, content and method of natural gas pipe network programming in cities were introduced in this paper. The application of graph theory, dynamic programming, neural networks, MCST method, constrained derivatives, etc. to pipe network programming were recommended in details. Through the development of natural gas pipe network programming , multiple objectives programming, fuzzy programming, grey programming were found to be the orientation of development of natural gas pipe network programming in cities. Furthermore, development of software in this field and introduction of software abroad should be stressed to improve the programming efficiency. Key Words: natural gas pipeline network programming purpose significance content method optimization the actual state development
