摘要

The procedure of selecting elements (objects) from a database under pre-established conditions is frequently encountered in decision-making problems. Even though many methods exist to facilitate the manipulation of data in a database, one of the most popular ones is a declarative language known as Structured English Query Language (SQL). Although SQL can easily capture the mechanical intent of a query, it lacks the ability to capture the semantics of a query. We can group and slice up collections of data in a variety of ways, but each division of the record collection proceeds along crispy lines. The use of fuzzy logic helps in the solution of the problem that arises when using crispy functions for extracting data from a database. Several problems are encountered when trying to apply fuzzy logic to practical problems. Among them, the fuzzy sets definition. Difficulties encountered in the development of this task negatively affect the employ of fuzzy logic, especially in developing relatively small non-repetitive engineering projects. This paper presents an easy-to-use methodology for the application of fuzzy logic for extracting rows from a database in the decision-making process. At the end, a simple case study is presented: The selection of a construction company in a bidding process.
