The International Symposium on the Analytic Hierarchy Process (ISAHP) takes place every two years. It brings together researchers, teachers and users of AHP and ANP to share their research and experiences in decision making. The symposium organizing and scientific committees represent all five continents, bringing the research, applications and perspectives of their areas of the world to this truly international forum.
The First International Symposium on the Analytic Hierarchy Process (ISAHP) was organized in Tianjin, China way back in 1988. The locations of the subsequent twelve ISAHPs were Pittsburgh, USA; Washington DC, USA; Vancouver, Canada; Osaka, Japan; Bern, Switzerland; Bali, Indonesia; Hawaii, USA; Viña del Mar, Chile; Pittsburgh, USA; Sorrento, Italy; Kuala Lumpur, Malaysia; and Washington DC, USA. The fourteenth ISAHP will be organized in London UK in 2016.
