The development of a decision support system in multimodal transportation routing within Greater Mekong sub-region countries

The objective of this research is to develop a decision support system (DSS) which can accommodate evaluation models to optimise multimodal transportation routing within Greater Mekong sub-region countries (GMS). This model is the combination of a number of models, the Analytic Hierarchy Process (AHP) which can help to bring consistency weight whose decision criteria - both quantitative and qualitative - are expressed in subjective measures according to the point of view of users. The quantitative factors are found by multimodal transport cost model and qualitative factors by using factor analysis. Then, it is followed by the Zero-One Goal Programming (ZOGP) which can integrate weights from the AHP to achieve an optimal multimodal transportation routing based upon user constraints. The analysis results, software developed, recommendations and limitations are also presented.
