| Abstract: | Seismic reliability optimization of gas pipeline system, provides a scheme for the system reconstruction,so reliability analysis of the gas pipeline system is deepened.Combining with recursive decomposition algorithm which is used to calculate the gas pipeline system reliability,genetic algorithm is presented to optimize the gas pipeline system subject to earthquake.As an example,the method is applied to Shenyang city's gas pipeline system.As the results subject to three different restrictions,one of three optimization systems can be chosen as reconstruction scheme according to the requirement of system reliability. |
| Keywords: | seismic reliability genetic algorithm optimization |
