| Abstract: | Based on characterstic of the urban gas networks and optimization theory,the paper builds up optimization model for the urban gas networks,in which the objective function is the least pipeline investment,the restrictive conditions are continuity function,pressure falling function and loop balance function.The urban gas networks is optimized with Lagrange arithmetic and pipe diameter optimization software is developed. |

| Keywords: | urban gas networks optimization design pipe diameter optimization |
