Strategic airline alliances are an increasingly common strategy for enhancing airline competitiveness and satisfying customer needs, especially in an era characterized by blurring industry boundaries, fast-changing technologies, and global integration. Airlines have been very active in utilizing this form of strategic development. However, the selection of a suitable partner for a strategic alliance is not an easy decision, involving a host of complex considerations by different departments. Furthermore the decision-makers may hold diverse opinions and preferences arising due to incomplete information and knowledge or inherent conflict between various departments. In this study fuzzy preference programming and the analytic network process (ANP) are combined to form a model for the selection of partners for strategic alliances. The effects of uncertainty and disagreement between decision-makers as well as the interdependency and feedback that arise from the use of different criteria and alternatives are also addressed. This generic model can be easily extended to fulfill the specific needs of a variety of companies. (C) 2011 Published by Elsevier B.V.

This is a reply to the comments on the previously published paper entitled "Using a modified grey relation method for improving airline service quality". The commentators question that the paper does not offer any improvement over Chen and Tzeng's (2004) work and uses the same data as in Liou, Tsai, Lin, and Tzeng's (2011b) paper. However, the modified grey relation described therein actually does improve on Chen and Tzeng's (2004) work in two ways. First, the ideal and negative ideal referential sequences are replaced by the aspired to and tolerable levels. Second, the similarity used in the grey relation model is transformed into a weighted gap, "the smaller the better". The same survey data is used in both papers, but the targets and purposes differ. One is focused on economy class passengers, while the other targets all passengers. Therefore, we argue that the comments indicate misunderstanding of the modifications. (C) 2011 Elsevier Ltd.
