Abstract
Although the Delphi and AHP techniques have been extensively utilised in maritime transport research, the application of a combination of both techniques together in this sector is still limited. Hence, this paper aims to review the application of a combined Delphi and AHP method in maritime transport research through a literature review process. Among others, this study looks into the area of research, the number of expert respondents employed, the minimum prerequisite set for the selection of respondents and whether there is a similarity of respondents in both the Delphi and AHP techniques. In a period that spans around 11 years between 2004 and 2014, it has been discovered that only a total of 8 studies involving the shipping and port sub-sectors have applied the combined method. It is hoped that this review could provide some guidance to researchers in the maritime transport or other relevant areas on how the combined technique could be implemented in future research.

This paper aims to review the application of a combined Delphi and AHP technique in maritime transport research through a literature review process from accessible literature until early 2015 that could be traced through the Google Scholar as well as through the Mara University of Technology E-journal integrated search engine
Summary
Maritime transport has grown into a specialised field of research This is evidenced from the increasing number of journals and conferences dedicated to maritime transport. This is not surprising because of the prominent role played by maritime transport in facilitating global trade. Owing to the complexity of the problems, different aspects of the unit of analysis have to be taken into account as the consequences of the problems are normally far reaching. In addressing this difficulty, complex decision making processes have been undertaken to enable the achievement of a desirable outcome. Ever since they were introduced in 1963 and 1980 respectively, both methods have been extensively used either individually or in combination with other methods in the research process
