In order to assess construction scale of the new port of Kikori in Papua New Guinea,a comprehensive forecasting method was proposed,consisting of four parts:regression analysis model,gravity model for hinterland container transportation demand,multi-objective fuzzy port evaluation model and port selection model based on Logit model.The container transportation demand in hinterland of Kikori Port in Papua New Guinea was forecasted.The traffic volume of containers generated from hinterland provinces at different ports was measured so that the container throughput of Kikori Port could be forecasted reasonably,which could provide support for assessing the necessity of the new Kikori Port.This method can forecast container throughput at a new port scientifically and objectively on basis of less fundamental data.It is suitable for throughput forecast in extremely underdeveloped country or region,where is short of statistical data and difficult to conduct survey due to security issues.The forecast method can assist with construction and consulting projects of overseas ports.
