When applied in a group environment, computation of AHP becomes more difficult and complicated. Although the geometric mean method (GMM) is known to be most common used with AHP for aggregation of judgments of the experts in the group, it may ignore variations among the experts' opinions. This paper proposed a group decision technique based on the preferential difference and rank concept. The proposed method used the preferential difference to accommodate strong opinions of the experts in the group while using the DEA/AR exclusion model to give more priority to the alternatives that were put in high ranks more often. The data set used by previous literature, simulated data sets and the case study of Thailand sugar industry for identification of the SWOT sub-factors with their priorities were used to test the effectiveness of the proposed method. In this paper, the group decision techniques by Huang et al. (2009), Angiz et al. (2012) and GMM were used as baseline methods to compare against the proposed method.

The results found that performance measurement for SMEs in the manufacturing sector in Thailand agreed with most variables at a high level, except for product usage and service at a medium level. When considering each entrepreneur individually, they had medium net profit at 11–15 %. When comparing performance measurements related to lean manufacturing, it was found that factors affected a high net profit of 15 % and they should continually work on it in order to ensure product quality, process quality, waste, defects, suppliers, work-in-process, output, lead time, delivery lead time, and inventory.
