The outsourcing of logistics activities to third-party logistics service providers (3PL) has become a common practice by many companies. The majority of research in this field is of exploratory type and is mainly focused on reasons, benefits, and risks to work with the 3PL as well as the role of those in supply chain management. This paper presents a literature analysis on 3PL selection and evaluation. This selection is a very complex process that depends on several factors. The selection criteria evolved a lot these past years and the 3PL have currently diversified by offering various services and by ensuring various activities. As for the methods of 3PL evaluation, they range from simple analytical techniques to multi-criteria methods. A comparison of these methods in terms of advantages and disadvantages is also presented in this paper.
