Purpose: The Analytic Hierarchy Process (AHP) is a multiple criteria decision-making method extensively used in various fields. Prioritization of decision criteria or alternatives from pairwise comparison matrices in AHP has been studied extensively. This article proposed the “Double-Frontier DEA” approach for prioritization in AHP. This new approach uses two optimistic and pessimistic DEA models to obtain the best local priorities from a pairwise comparison matrix, regardless of whether it is fully consistent or not.Methodology: One of these methods is Data Envelopment Analysis (DEA). The combination of DEA and AHP (DEAHP) is used to obtain and aggregate weights in AHP. Studies show that DEAHP fails in obtaining and aggregating weights in AHP and sometimes produces priority vectors contrary to evidence for inconsistent pairwise comparison matrices that limits its application.Findings: This new approach uses two optimistic and pessimistic DEA models to obtain the best local priorities from a pairwise comparison matrix, regardless of whether it is fully consistent or not. Some numerical examples, including a real application of AHP for selecting an innovation team for a university, are provided to specify the advantages of the proposed approach and its potential applications.Originality/Value: The double-frontier DEA approach generates true weights for fully consistent pairwise comparison matrices and best local priorities for inconsistent pairwise comparison matrices, that are logical and fit subjective judgments of decision-makers.

Purpose: The purpose of this research is to identify and prioritize international markets entry strategies in plastics industry.Methodology: The research method of the study is explorative-descriptive and its statistical population includes managers and officers working in small and medium-sized enterprises in the plastic industry, which are the members of the Bojnord Chamber of Commerce, Industries, and Mines. The sampling method of the study consists of snowballing sampling and purposive sampling, and the sample size is equal to 19 experts. Data collection instrument was questionnaire, which its validity and reliability were confirmed using content validity ratio and inconsistency ratio mechanism, respectively. To analyze data, Analytic Hierarchy Process (AHP) technique was used.Findings: The findings indicate that international markets entry strategies in plastics industry consists of seven strategies, including export, license, management contract, contract manufacturing, turnkey operation, foreign direct investment and strategic alliances, and criteria to select these strategies include four categories of factors related to host country, factors related to product, factors related to company, and factors related to home country. Furthermore, the research findings indicate that the most important criterion to select international markets entry strategies is factors related to company and the best international markets entry strategy is export.Originality/Value: The findings of this research help managers to evaluate, prioritize, and select international markets entry strategies using AHP technique in an effective and efficient manner.
