FAHP-based heat supply secondary pipe network leakage risk assessment method

The invention relates to the field of heat supply pipe network pipeline leakage monitoring and puts forward a secondary pipe network leakage risk assessment method. Zone-based meter installation and intelligent monitoring point arrangement can be conducted according to leakage risk grade indexes of a secondary pipe network, and a reasonable intelligent leak detection system can be built. A technical solution adopted for the method disclosed in the invention is that the FAHP-based heat supply secondary pipe network leakage risk assessment method comprises the following steps: in a first step, heat supply pipeline leakage reasons are investigated and summarized, and main factors for pipeline leakage are determined; in a second step, a heat supply secondary pipe network leakage risk grade assessment model is built, wherein p=leakage risks of a certain heat supply pipe network. The method disclosed in the invention is mainly applied to heat supply pipe network pipeline leakage monitoring occasions. 本发明涉及供热管网管道泄漏监
