The supplier evaluation is considered a key element in the procurement of resources. In this stage, a characterization of suppliers is carried out, based on a documentary review, interviews, and experiences acquired in similar projects, which allows managers to make decisions in the project. Some of the main difficulties that methods present in developing supplier evaluation are associated with inadequate uncertainty modeling and the lack of any mechanism for the treatment of multiple expert preferences on various criteria, which leads to loss of time and information. The objective of this paperis the application of fuzzy techniques for the evaluation of Video Surveillance technology providers, based on the fuzzy analytic hierarchy process and the 2-tuple linguistic representation model, to treat uncertainty in decision-making. This is based on the management of information provided by multiple experts. Results obtained are easily interpreted by evaluators, without loss of information.

Palabras clave
