Conclusions
This paper, as a follow-up study to Ho (2008), reviewed the literature on the integrated AHP approaches and applications published between 2007 and 2016 and compared the findings to studies published in the previous decade, i.e., 1997-2006. In addition to the searching and filtering criteria used in Ho (2008), this paper focused on those articles published in international journals with high ranking, including A/A* journals on the Australian Business Deans Council (ABDC) journal list, and/or 3/4/4* journals on the Association of Business Schools (ABS) journal list in the United Kingdom. This criterion would not only let researchers and practitioners learn about the prominent and state-of-the-art integrated AHP approaches and applications, but also provide researchers valuable insights of developing, applying, and publishing novel integrated AHP approaches in high-ranking journals. The findings of this paper are summarized as follows. First, the integrated AHP-fuzzy approach replaced the integrated AHP-GP approach and the integrated AHP-QFD approach as the most popular integrated AHP approach in the period from 2007 to 2016. Second, this study observed that the manufacturing sector replaced logistics as the most popular application area. Consistent with Ho (2008), this study concluded that both manufacturing and logistics sectors remained the top two application areas to which the integrated AHP approaches were most frequently applied. Third, supplier evaluation and selection replaced distribution network optimization as the most commonly studied problem. Fourth, there were more publications on the integrated AHP approaches during the period from 2007 to 2016. It is also estimated that AHP integration with more than one method will attract more attention. Fifth, the International Journal of Production Research replaced the European Journal of Operational Research as the most commonly published journal. Finally, several new applications of new AHP integrations are recommended. These topics would assist scholars in filling the literature research gaps.
