Selection of leading products of petrochemical industry in the Guangxi Beibu Gulf Economic Zone

This paper constructed indicators (criteria) system for the leading product selection of petrochemical industry in Northern Gulf of Guangxi, and retrieved criteria information for each product through the well-designed questionnaire. We formalized the leading products selection as a multi-criteria decision problem of which the criteria value is linguistic fuzzy information. In this paper, we proposed a method to transform linguistic information to two-tuple linguistic numbers, calculate the overall assessment value of the product from products criteria information using weighted aggregation operators, and finally support the selection via a ranked alternative set after comparing assessment values.
